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.

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 90?m 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.
