IBA Lifesciences Twin-Strep-tag™ Capture Kit

Descrizione

Twin-Strep-tag™ Capture Kit is intended for site-directed, reversible capture of Twin-Strep-tag™ fusion proteins for biomolecular interaction analysis using surface plasmon resonance (SPR) devices. The kit provides Strep-Tactin™XT, SPR Immobilization Buffer, Regeneration Buffer, and GFP-Twin-Strep-tag™ as control protein. It enables the highly stable immobilization of the ligand based on the unique Strep-Tactin™XT:Twin-Strep-tag™ interaction, which operates with pM affinity. The key benefits are:
• Indirect immobilization protecting the ligand from chemical modification as well as inactivation or manipulation by the immobilization procedure
• High affinity enabling measurements over a long period (high affinity in low pM range; T1/2 = 13 h)
• Chip can be regenerated easily by an established procedure – cost effective
• Ligands can be captured directly from complex samples due to the high affinity and specificity of the Twin-Strep-tag™:Strep-Tactin™XT interaction The use of unconjugated Strep-Tactin™XT requires a license that is provided with the purchase of the kit as limited use license.
