Product Details

Product Form
Streptavidin conjugated to R-Phycoerythrin - lyophilised
Reconstitution
Reconstitute with 1ml distilled water
Preparation
Pure Streptavidin is reacted with Succinimidyl 4- (N-maleimido-methyl) cyclohexane - 1- carboxylate (SMCC). R. Phycoerythrin is reacted with N-succinimidyl 3-(2 - pyridyldithio) propionate (SPDP) and activated by reduction with dithiothreitol. The two substituted proteins are reacted together to give covalent conjugates, which are selected by medium pressure liquid chromatography on gel filtration columns of AcA34 ultrogel.

STAR4A conjugates show negligible non-specific binding to non-biotinylated macromolecules, and therefore gives very low backgrounds.
