- Product name
PurKine™ Strep II-Tag Strep-Tactin Resin 4FF
- Application notes
PurKine™ Strep II-Tag Streptactin Resin 4FF effectively purifies high levels of Strep II-tagged proteins expressed in any express system such as, E. coli, insect, and mammalian cells in gravity column procedures at a variety of scales. The Resin consists of 90μm beads of cross-linked 4% agarose, to which Strep-Tactin has been coupled. Tests confirm that performance equals or exceeds popular Strep-Tactin resins from other suppliers, and no decrease in performance occurs after at least five repeated uses. In addition, its high flow properties make it excellent for scaling-up.
Fig.1. Abbkine PurKine™ is series of unique purification portfolio from settled resin, prepacked spin columns and full kits for your most types of sample purification and preparation.
Fig.2. Rather than traditional method of resin production, Abbkine is taking advantage of the latest synthetics process with cutting-edge techniques for the resin development and accessories optimization. PurKine™ tools are available for your samples from fusion proteins, nucleic acids, antibodies and biomolecule markers with improved productivity, simplified workflow and cost saving.
Liquid solution with 50% slurry in 20% ethanol.
- Features & Benefits
• High capacity—Up to 6 mg Strep II-tagged protein per mL of resin.
• High performance—Strep-Tactin is one of the most stable proein.Physiological conditions and mild elution is performed using Strep-Tactin which preserve target protein activity.
• 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.
• Robust—highly crosslinked beads tolerate linear flow rates up to 300cm/hour.
- Storage buffer
Liquid in PBS buffer containing 20% ethanol.
- Storage instructions
Stable for one year at 2-8°C from date of shipment. Do not freeze.

PurKine™ Strep II-Tag Strep-Tactin Resin 4FF system is based on innovative high-capacity matrix for convenient single-step purification of Strep II-Tag proteins. The Strep-tag II is a short peptide (8 amino acids, WSHPQFEK), and binding affinity of the Strep-tag II to Strep-Tactin is nearly 100 times higher than to streptavidin. 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™ Strep II-Tag Strep-Tactin Resin 4FF is also available as prepacked spin column and kit formats.
