![]() In that case, what the others post is correct. In that case, the bias resistors you see in your diagram are what will determine the DC set point of Vb is. This means that DC will be blocked and AC will pass through. In that case, all of the bias resistors really don't matter because the input voltage will drown out their effect.Īlternately, something like this is commonly driven by a capacitively coupled source. If it's low, then it's as if you're applying a true voltage source to Vb. If an op-amp or a similar amplifier stage drives Vb, then the output impedance should be quite low. Without it you can't really know for sure. The best way to learn how a transistor works is to examine it in real-life circuits.You would really need to know the output resistance of the input voltage source to Vb. If you're burnt out on conceptual stuff, take a trip to the next section. This means the emitter must generally be at a higher voltage than the collector. In active and saturation modes, current in a PNP flows from emitter to collector. And, to put a PNP into active mode, V E must be at a higher voltage than V B, which must be higher than V C.Īnother opposing characteristic of the NPNs and PNPs is the direction of current flow. You pull the base low to turn the PNP on, and make it higher than the collector and emitter to turn it off. ![]() To find out which mode a PNP transistor is in, reverse all of the signs.įor example, to put a PNP into saturation V C and V E must be higher than V B. What about PNP transistors? PNP's work a lot like the NPN's - they have the same four modes - but everything is turned around. Relating to the PNPĪfter everything we've talked about on this page, we've still only covered half of the BJT spectrum. It's good to know it's there, but it's rarely designed into an application. Reverse active mode isn't usually a state in which you want to drive a transistor. A transistor in cutoff mode is off - there is no collector current, and therefore no emitter current. Cutoff ModeĬutoff mode is the opposite of saturation. This value means that V C must be slightly greater than V E (but both still less than V B) to get the transistor in saturation mode. ![]() Transistor datasheets will define this voltage as CE saturation voltage V CE(sat) - a voltage from collector to emitter required for saturation. A small voltage drop will form between those nodes. For a lot of transistors (at room temperature) we can estimate this drop to be about 0.6V.Īnother reality bummer: there won't be perfect conduction between emitter and collector. There are many abbreviations for this voltage drop - V th, V γ, and V d are a few - and the actual value varies between transistors (and even further by temperature). The voltages from base to emitter (V BE), and the from base to collector (V BC) set the transistor's mode:īecause the junction from base to emitter looks just like a diode, in reality, V BE must be greater than a threshold voltage to enter saturation. To determine which mode a transistor is in, we need to look at the voltages on each of the three pins, and how they relate to each other. Current flows from emitter to collector (not, exactly, the purpose transistors were designed for). Reverse-Active - Like active mode, the current is proportional to the base current, but it flows in reverse.Active - The current from collector to emitter is proportional to the current flowing into the base.No current flows from collector to emitter. Cut-off - The transistor acts like an open circuit.Current freely flows from collector to emitter. Saturation - The transistor acts like a short circuit.(When we talk about current flow through a transistor, we usually mean current flowing from collector to emitter of an NPN.) They have four distinct modes of operation, which describe the current flowing through them. ![]() Unlike resistors, which enforce a linear relationship between voltage and current, transistors are non-linear devices.

![]() Safety Ģ-Mercaptoethanol is considered toxic, causing irritation to the nasal passageways and respiratory tract upon inhalation, irritation to the skin, vomiting and stomach pain through ingestion, and potentially death if severe exposure occurs. Some carbamate protecting groups such as carboxybenzyl (Cbz) or allyloxycarbonyl (alloc) can be deprotected using 2-mercaptoethanol in the presence of potassium phosphate in dimethylacetamide. This prevents them from digesting the RNA during its extraction procedure. Numerous disulfide bonds make ribonucleases very stable enzymes, so 2-mercaptoethanol is used to reduce these disulfide bonds and irreversibly denature the proteins. Denaturing ribonucleases Ģ-Mercaptoethanol is used in some RNA isolation procedures to eliminate ribonuclease released during cell lysis. It is often used in enzyme assays as a standard buffer component. Preventing protein oxidation Ģ-Mercaptoethanol and related reducing agents (e.g., DTT) are often included in enzymatic reactions to inhibit the oxidation of free sulfhydryl residues, and hence maintain protein activity. Ģ-Mercaptoethanol is often used interchangeably with dithiothreitol (DTT) or the odorless tris(2-carboxyethyl)phosphine (TCEP) in biological applications.Īlthough 2-mercaptoethanol has a higher volatility than DTT, it is more stable: 2-mercaptoethanol's half-life is more than 100 hours at pH 6.5 and 4 hours at pH 8.5 DTT's half-life is 40 hours at pH 6.5 and 1.5 hours at pH 8.5. DTT is also a more powerful reducing agent with a redox potential (at pH 7) of −0.33 V, compared to −0.26 V for 2-mercaptoethanol. However, since 2-mercaptoethanol forms adducts with free cysteines and is somewhat more toxic, dithiothreitol (DTT) is generally more used especially in SDS-PAGE. Because of its ability to disrupt the structure of proteins, it was used in the analysis of proteins, for instance, to ensure that a protein solution contains monomeric protein molecules, instead of disulfide linked dimers or higher order oligomers. RS–SR + 2 HOCH 2CH 2SH ⇌ 2 RSH + HOCH 2CH 2S–SCH 2CH 2OHīy breaking the S-S bonds, both the tertiary structure and the quaternary structure of some proteins can be disrupted. In the case of excess 2-mercaptoethanol, the following equilibrium is shifted to the right: Some proteins can be denatured by 2-mercaptoethanol, which cleaves the disulfide bonds that may form between thiol groups of cysteine residues. This makes 2-mercaptoethanol useful as a protecting group, giving a derivative whose stability is between that of a dioxolane and a dithiolane. Reactions Ģ-Mercaptoethanol reacts with aldehydes and ketones to give the corresponding oxathiolanes. Thiodiglycol and various zeolites catalyze the reaction. ![]() Due to its diminished vapor pressure, its odor, while unpleasant, is less objectionable than related thiols.Ģ-Mercaptoethanol is manufactured industrially by the reaction of ethylene oxide with hydrogen sulfide. It is widely used because the hydroxyl group confers solubility in water and lowers the volatility. ME or βME, as it is commonly abbreviated, is used to reduce disulfide bonds and can act as a biological antioxidant by scavenging hydroxyl radicals (amongst others). This method enabled > 90 % overall recovery of unformulated DS at ≥ 150 g/L.2-Mercaptoethanol (also β-mercaptoethanol, BME, 2BME, 2-ME or β-met) is the chemical compound with the formula HOCH 2CH 2SH. Most of the rinse was combined with the retentate to hit the target protein concentration. After the retentate was collected, a minimal volume of buffer was added for the UF rinse. During the UF/DF process, the antibody was initially concentrated to 90 g/L, diafiltered, and concentrated to ≥ 180 g/L, then the retentate was collected. Analysis showed that the Capto S run removed the excipients with yields of ≥ 96%. In addition, Capto S has lower resin costs, takes less time to process, and uses milder elution conditions. A Capto S column was chosen over Protein A chromatography to remove excipients from formulated drug substance because of its higher binding capacity. Fortunately, a sufficient supply of formulated DS was available for reprocessing. Since the pilot plants were not available for large-scale campaigns, a creative alternative was needed to produce 2 kg of antibody from formulated DS for these studies. During process scale-up, the project team decided to make a high-concentration mAb drug substance for subcutaneous injection and change the formulation. The scope of this work is two-fold: 1) excipients removal from formulated mAb drug substance by Capto S chromatography and 2) UF/DF process development to make high-concentration drug substance (DS) for subcutaneous injection. ![]() Funds are specifically used to catalyze matching funds/resources from various sources, including public funds (municipal and national funds), donors, financial institutions, private funds (e.g. The program leverages and channels investments for farms, mills, and water resource management.

Watersheds that provide drinking water for communities downstream are better managed, primarily by promoting sustainable agricultural practices, improved water governance, increased investments in improving agricultural practices and improving water systems, and increased policy influence around integrated water resource management. The program delivers results and generates impacts in three areas. Since, the program has been expanding to other regions in Latin America. Blue Harvest forms part of CRS’ larger initiatives on Water-Smart Agriculture in Latin America and CRS Coffeelands program. The program started in Central America focusing on protecting watersheds that provide drinking water to downstream communities by promoting water-smart coffee production and milling practices. In early 2014, CRS launched Blue Harvest, a program explicitly designed to restore and protect water resources for people in coffeelands. Beyond field-based projects, we have also been proactive in putting water resources on the agenda of the coffee industry: we have written extensively in the Coffeelands blog and in coffee journals we have spoken in conferences and events we have produced several short videos and we have contributed to the SCA Sustainability Council issue brief titled A Blueprint for Water Security in the Coffeelands. Through agriculture and water projects, we have been promoting sustainable coffee production to protect and improve water resources. Since 2012, CRS has been working to highlight the impacts that coffee has on water resources in places where coffee is produced. |
