Streptavidin

Overview

Streptavidin is a highly regarded protein used in various biotechnical applications, including immunoassays, histochemistry, FISH (Fluorescence In Situ Hybridization), flow cytometry, microarrays, and blot analysis. Its unique ability to bind biotin with remarkable strength (Kd ~10^-15 M) makes it an invaluable tool in research and diagnostic settings.

Key Features

• High-affinity binding to biotin
• Non-glycosylated, tetrameric structure
• Low nonspecific binding compared to avidin
• Ideal for various assay techniques
• Compatible with multiple labeling applications
