Streptavidin Affinity Chromatography Resin NRPB61, 8~20 mg Strep-tag II-tagged protein/mL (CAT#: STEM-AL2-0895-ZJF)

This product is a chromatography medium intended for biotinylated biomolecule purification. It uses 4% cross-linked agarose as the support phase. The functional chemistry is based on ST2 (streptavidin mutant). The medium is intended for packed-bed chromatography under the conditions stated in the source data. The source data define the applicable flow, pH, and pressure conditions for the supplied configuration. Chemical compatibility information supports equilibration, washing, regeneration, and cleaning workflows where applicable. Storage conditions are specified to maintain the medium before use and between operations. The product can be integrated into laboratory or process purification workflows consistent with its stated separation mechanism. Strep-tag is a trademark of IBA Lifesciences GmbH and is referenced here only to identify the tagged target protein.
