Strep-Tactin(R)XT BLI Coupling Kit

Strep-Tactin(R)XT BLI Coupling Kit is intended for site-directed, reversible capture of Twin-Strep-tag(R) fusion proteins for biomolecular interaction analysis using Bio-Layer Interferometry (BLI). It provides Strep-Tactin(R)XT, Immobilization Buffer, Ethanolamine, EDC, and s-NHS sufficient for coating of 96 biosensors (1 tray). The pM affinity of Strep-Tactin(R)XT for Twin-Strep-tag(R) fusion proteins allows specific capture even from complex samples, e.g., culture supernatants. Coated biosensors can be easily regenerated by application of the provided Regeneration Buffer without loss of the Strep-Tactin(R)XT coating which enables multiple re-uses.
