What is a nonelectrolyte? Nonelectrolytes: Chemicals that dissociate in water break into ions that form electrolytes. Electrolytes are classified as strong, weak, or non-electrolytes based on the amount of chemical that dissociates in water. Answer and Explanation: A nonelectrolyte is a chemical...
In chemistry, cationic polymerization is a type of chain growth polymerization in which a cationic initiator transfers charge to a monomer which then becomes reactive. This reactive monomer goes on to react similarly with other monomers to form a polymer. What is cationic and anionic polymerization?
Which of the following sugar is an L-sugar? Peptide is PISKTVAHM (The M would be converted to Hse during CNBr cleavage) Question: How much of the peptide would you need to dissolve in 10 ml of the buffer to prepare a 10X (500 M) stock solution? Assume that the MW of the peptide...
该反应是快速、特异性的,并且由于生物素体积小 (MW = 244.31) 而不太可能干扰生物分子的自然功能。 生物素与链霉亲和素和亲和素特异性结合,形成具有强亲和力 (Kd, ~ 10-14 mol/L) 和快速接通速率的复合物。即使在高/低 pH 值、高温、高盐浓度等恶劣条件下,复合物也非常稳定。 生物素-亲和素和链霉...
Water Solubility Soluble in water and ethanol General Description Guanidine thiocyanate is one of the cheapest and easiest to prepare of the guanidine salts. Guanidine Thiocyanate is an ultrapure, molecular biology grade reagent. It is free of detectable nuclease and protease activity and is a stron...
What is latent heat in chemistry? 50.0 mL of 2.09 M NaOH(aq) is mixed with 50.0 mL of 2.20 M HCl in a Styrofoam calorimeter. Calculate the moles of NaOH(s) added to the calorimeter. What is the heat capacity of a substance if it takes 5.2 kJ of heat to warm 597.8 g by 46.6 de...
If chemical reaction networks are to be used as computing devices, a necessary intermediate step is to design reaction systems that implement a given stoichiometric matrix. Constraints on the chemistry imposed by the desired network stoichiometry itself thus become an issue in the design process, ...

How is UNG/UDG used in qPCR? As PCR can amplify such tiny amounts of DNA, preventing contamination is essential: even small amounts of contamination can produce false positives in your experiments. Contamination can include cross-contamination from other samples, DNA contamina...
