Streptavidin Magnetic Beads

Description

Streptavidin Magnetic Beads are 1 µm superparamagnetic particles covalently coupled to a highly pure form of streptavidin. Captured substrates can be useful as ligands in subsequent experiments including mRNA isolation and the capture of primary or secondary antibodies.

Beads are supplied as a 4 mg/ml suspension in phosphate buffer (PBS) (ph 7.4) containing 0.1% BSA, 0.05% NaNand 0.05% Tween® 20.
