WebJan 10, 1997 · Thiolate monolayers are ideal because they are easily modified before or after deposition. The works contained within this dissertation include interfacial characterization (infrared reflection absorption spectroscopy, ellipsometry, contact angle, scanning probe microscopy, and heterogeneous electron-transfer kinetics) and various … WebDissolve the antibody at 50-100 uM (7.5-15 mg/mL for IgG) in 1X PBS or 10-100 mM phosphate, Tris, or HEPES buffer, pH 7-7.5. As an optional step, if you wish to free up more thiol groups from the disulfide bonds in the protein, you may add ~10-fold molar excess of TCEP at this stage. Incubate the reaction solution for ~30 minutes. fmv pliche

WebSo thiols are good nucleophiles. Thiolate anions are even better nucleophiles. And so the thiolate anion is going to function as the nucleophile. The partially positive carbon is … WebUnder either base or nucleophile catalysis the ease with which the thiol is deprotonated to the thiolate, i.e. the p K a of the thiol, is also a factor to be considered. Thiols are, generally, significantly more acidic than the corresponding alcohols , however, p K a values can span an impressive range from, for example, 4.13 for 2,4,6 ...
