Long-chain Streptavidin (r-cSA-SH) : 100 mg

Long-chain Streptavidin (r-cSA-SH) is a high-purity recombinant streptavidin with accessible sulfhydryl groups, ideal for bioconjugation, immobilization, and molecular biology applications. This protein is widely used in biosensor development, immunoassays, and affinity chromatography due to its high biotin-binding capacity and stability.

The sulfhydryl modification allows for covalent coupling to surfaces, nanoparticles, or fluorophores, enabling versatile applications in diagnostics, research, and biotechnology workflows.
