Streptavidin, Fluorescent Dye Label, AFDye 555 dye label, 5mg

Recombinant Streptavidin protein that has been covalently labeled with a fluorescent dye. The following fluorescence dye labels are available: AFDye 488 AFDye 555 AFDye 647 IR750 NOTE 1: AFDye 488 (similar to FITC), AFDye 555 (similar to Cy3), AFDye 647 (similar to Cy5) are analogs of AlexaFluor® 488, AlexaFluor® 555, and AlexaFluor® 647 dyes, respectively. NOTE 2: IR750 dye is ithe analog of the IRDye® 750 dye. Streptavidin is a homo-tetrameric protein found in the culture broth of Streptomyces avidinii. Similar to avidin, one mole of streptavidin can bind 4 moles of biotin with a high affinity. Streptavidin lacks carbohydrate side chains present on avidin and has a neutral isoelectric point, which reduces nonspecific binding compared to avidin. Streptavidin is extensively used for various biological applications, including ELISA, IHC, TRFIA, quantification of PCR product, isolation of single-stranded nucleotide, purification of biomolecule, and monoclonal antibody production as well. Compared to native streptavidin, our recombinant streptavidin has improved stability and solubility through the removal of activity-unrelated amino acid sequences.
