Streptavidin ST Beads 4FF is a chromatography medium for one-step purifying Strep-tag II fusion proteins from various of expression system. The Strep-Tag II peptide is an eight amino acid fusion tag(Trp-Ser-His-Pro-Gln- Phe-Glu-Lys), which has negligible effects on recombinant proteins. The ligand immobilized on high-crossed linked 4% agarose is a specially recombinant protein. Purification under physiological conditions and mild elution preserves the activity of the target protein.
PreCap Streptavidin ST is a prepacked ready to use column. PreCap Streptavidin ST 1ml and 5ml columns are packed with 1ml and 5ml of Streptavidin ST Beads 4FF. PreCap Streptavidin ST can be adapted to all kinds of chromatography system, such as ÄKTA. It is easy to operate.
