Spotlight on Streptavidin

At 2BScientific Limited, we are proud to distribute Streptavidin from Kementec, a trusted supplier that consistently provides high performance reagents relied upon by researchers for their outstanding specificity and reproducible performance.

Produced by Streptomyces avidinii and purified directly from fermentation broth, Kementec’s Streptavidin delivers consistent, high-purity quality. With biotin binding activity exceeding 13 U/mg and a non or very low charged, non-glycosylated structure. It ensures clean, reliable results while minimising background signal. Its strong and stable interaction with biotin has made Streptavidin a critical reagent for a plethora of research and diagnostic workflows.

Kementec’s Streptavidin can be utilised across a wide range of applications. In immunoassays it works in tandem with biotinylated antibodies for detection, fluorescent reagents, and conjugation to gold particles. In both Western and Southern blotting, it produces a reproducible signal with excellent signal-to-noise ratios. For nucleic acid assays, it enables efficient labelling and detection of DNA and RNA, while in purification workflows, immobilised Streptavidin supports the efficient capture of biotinylated molecules.

With its proven performance and broad applicability, Kementec’s Streptavidin remains an essential tool for researchers seeking dependable results across immunoassays, molecular biology, and purification workflows.
