Streptavidin is a 52.8 kD tetrameric protein obtained from Streptomyces avidinii. It binds to biotin with a very high affinity and is one of the strongest interactions in nature with a dissociation constant of 10-14 mol/L. It is used in a wide range of applications including ELISA, flow cytometry, molecular biology, and bionanotechnology.Product Details

- Recommended Usage
To coat one 96-well plate dilute 24 µL of Purified Streptavidin into 11.976ml of 1X Coating Buffer (Cat. No. 421701, Coating Buffer 5X concentrate). Final concentration in the coated plate is 2 µg/mL. This recommendation is to perform the protocol for HLA class I ELISA to evaluate Flex-T™ peptide exchange. For other applications the reagent needs to be optimized.
