Spacer arm 2.8 angstroms.Protein modification reagent. Used to introduce protected thiol groups onto primary amines. The protected sulfhydryl prevents dipeptide formation. When treated with hydroxylamine a free sulfhydyl group can then be conjugated to maleimide modified protein. Purity >96% by HPLC. Soluble in DMSO and methylene chloride.

- SATA adds a protected sulfhydryl that can be deprotected by hydroxylamine
- Allows long-term storage of the sulfhydryl-modified molecule
- Forms cleavable disulfide bonds with other sulfhydryl-containing molecules
- SATA reacts with primary amines (lysine residues and the amino terminus of a protein) to form stable amide bonds
- Preserves protein activity with its mild, non-denaturing reaction conditions
