Our Abpromise guarantee covers the use of ab239759 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Streptavidin-PE will bind to biotin allowing detection of biotinylated antibodies in Flow, microplate assays and microarrays. Streptavidin high affinity for biotin allows low background in cell sorting, immunofluorescence, in situ hybridization, or flow cytometry. Suitable for use with Mouse, Human and Rat samples.
Excitation: Blue Laser (488 nm), Green Laser (532 nm), Yellow-Green Laser (561 nm)

RelevanceStreptavidin is a tetrameric protein purified from Streptomyces sp. that binds very tightly to the vitamin biotin with a Kd of ~ 10-14 mol/l. The high affinity recognition of biotin and biotinylated molecules has made streptavidin one of the most important components in diagnostics and laboratory kits.
