概述 >
Description:
Streptavidin(iFluor488) is coupled steptavidin with iFluor488. Streptavidin(iFluor488) is highly sensitive to binds biotinylated proteins in enzyme immunoassay, immunoblotting, immunohistochemistry, flow cytometry systems.

Conjugate: iFluor488(Ex: 495nm, Em: 519nm), 2 moles iFluor488 per mole streptavidin
Concentration: 1mg/ml
Formation: Liquid, 10mM PBS(pH 7.5), 0.05% sucrose, 0.1% trehalose, 0.01% proclin300, 50% Glycerol
Storage: Store at –20 °C, protect from light

Background:
Streptavidin is a 53 kDa protein isolated from Streptomyces avidinii. Streptavidin has a molecular weight of 60 KD and contains 4 subunits. Each subunit can bind one molecule of biotin. Streptavidin has strong binding properties to avidin (Kd=10-15). Because of its strong non-covalent interaction with biotin, streptavidin can be used to detect and isolate biotinylated proteins.

Dilution factors are presented in the form of a range because the optimal dilution is a function of many factors, such as antigen density, permeability, etc. The actual dilution used must be determined empirically.
