PurKine Biotin-Tag Protein Purification Kit (Streptavidin)

PurKine Biotin-Tag Streptavidin Packed Column effectively purifies high levels of biotin and biotinylated substances in gravity column procedures at a variety of scales. The Resin consists of 90um beads of cross-linked 6% agarose, to which Streptavidin has been coupled. Tests confirm that performance equals or exceeds popular Streptavidin resins from other suppliers, and no decrease in performance occurs after at least five repeated uses.

High capacity—1 to 3 mg of biotinylated BSA per mL of resin.More than 120 nmol Biotin per mL of resin

High performance—Streptvidin has a low isoelectric point (pI=5) and no carbohydrate groups, resulting in low nonspecific binding.

Cost-effective—No performance decrease after at least five repeated uses of the same batch of resin.

Flexible—available in multiple formats including bulk resin, spin columns and complete kits.
Easy to use— Pre-formulated buffers available for kit formats.
Robust—highly crosslinked beads tolerate linear flow rates up to 500 cm/hour.

PurKine Biotin-Tag Purification system is based on innovative high-capacity matrix for convenient single-step purification of biotin and biotinylated substances. Biotinylated antibodies, proteins, peptides, nucleic acids and other molecules or interaction complexes can be captured, immunoprecipitated, removed or purified from samples using this streptavidin resin. The portfolio allow optimization of process for maximum protein yield, stability and solubility. Tests also confirm that no decrease in performance occurs after at least five repeated uses. The PurKine Biotin-Tag Purification resin is also available as prepacked spin column and kit formats.
