产品概述

Product Description

GenScript’s StrepCaptureXP Magnetic Beads (Cat. No. L01075) are next-generation affinity magnetic particles engineered for the efficient and high-throughput purification of Strep-tag® II and Twin-Strep-tag® fusion proteins. Functionalized with an innovatively engineered StrepCaptureXP ligand—a genetically optimized streptavidin variant—this product enables high-affinity, high-specificity capture proteins from complex biological lysates, including those derived from mammalian, bacterial, and insect expression systems.

Key Features

● High specificity and low background binding
● Alkali-tolerance is 0.1 M NaOH to 0.5 M NaOH
● Efficient, high-throughput purification, compatible with automated workflows
● Mild, reversible elution (50 mM Biotin)
● Broad buffer compatibility
● Robust performance across various expression systems
● Simple, streamlined operation
