Acetylthio PEG amine, also called thiolacetate PEG amine, is an amino PEG with protected thiol groups. Acetyl protected thiol group is stable in neutral condition and acetyl group can be deprotected from thiol group under acidic or alkaline conditions. Free thiol group is released upon deprotection of acetylthio. With thiol group protected, remaining functional groups, such as amines, azides, hydrazides, NHS, maleimides, DBCO, etc. can be used to react with other groups. PEGylated thioacetate derivatives are water soluble and can be used directly in aqueous buffer.

D-Biotin is a growth factor present in small amounts in every living cell. It is involved in naturally occurring carboxylation reactions. It occurs mainly bound to proteins or polypeptides. It is more abundant in the liver, kidney, pancreas, yeast and milk. Biotin levels are higher in cancerous tumors than in normal tissues. It is inactivated by binding to avidin.
D-Biotin may be used to elute proteins from avidin/streptavidin resins. It is widely used for dietary supplements and fortified foods. It is also used for tablets and hard-shell capsule preparation due to its pharmaceutical properties.
Essential vitamin that is important for amino acid and energy metabolism, and fatty acid synthesis. It is a prosthetic group in four mammalian carboxylase families and facilitates the binding and transfer of carbon dioxide.
Soluble in water (22 mg/100 mL), ethanol (80 mg/100 mL), more soluble in hot water and in dilute alkalies; insoluble in other common organic solvents. Soluble in 2 M Ammonium hydroxide (50 mg/mL - clear, colorless solution), dimethylformamide (1.7 mg/mL).
