Agarose Streptavidin

Features:

Prepared by conjugating streptavidin to heat stable, cross-linked 4% agarose gel beads. To ensure minimal steric interference and low nonspecific binding, streptavidin is conjugated through a hydrophilic spacer arm. Biotin binding activity of the streptavidin optimally preserved through proprietary coupling procedure. Can be used to separate biotinylated macromolecules from unbiotinylated materials or for solid phase binding assays. Streptavidin cannot be leached from gel with solutes such as Tris buffer. Low non-specific binding activity of gel. Protein concentration is 1 mg streptavidin per ml of settled agarose beads. Supplied as a 1:1 suspension in buffer. Binding capacity is approximately 1 mole biotinylated HRP per mole streptavidin.
