Streptavidins

Streptavidins — includes native streptavidin protein as well as its conjugates with enzymes, fluorophores, or reporter metals, leveraging the very strong streptavidin-biotin binding affinity for detection and purification in biochemistry research and immunoassay-based diagnostics.

Streptavidin conjugates such as HRP, FITC, R-PE, or maleimide are used by immunology and molecular biology researchers in ELISA, flow cytometry, western blot, and biotin-based nucleic acid hybridization assays. The streptavidin-Eu3+ complex is also used in time-resolved fluorescence detection for assays requiring high sensitivity.

Example products in this collection: TCI T3885 Streptavidin R-PE Conjugate, TCI S0951 9013-20-1 Streptavidin from Streptomyces avidinii, TCI T3531 Streptavidin Maleimide Conjugate, TCI S0966 Streptavidin FITC Conjugate, TCI S0993 Streptavidin DTBTA-Eu3+ Conjugate, TCI S0972 Streptavidin HRP Conjugate.

Choose the conjugate type (enzyme, fluorophore, or metal) according to the detection platform used, and pay attention to the label-to-protein ratio and the packaging form of solution or dried lyophilisate so that stability is maintained. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
