Streptavidin is a non-glycosylated polypeptide chain having a molecular mass of 240kD and containg 4 subunits each with a binding site for biotin. The Streptavidin is isolated by purification from fermentation broth. The neutral isoelectric point of Streptavidin and the high affinity of the biotin-streptavidin interaction result in a very quick reaction with a high signal to noise ratio. Streptavidin does not react unspecifically with endogenous lectins when used in immunological assays on cells and tissues. Streptavidin is non- or very low charged around pH 7, reducing NSB to charged molecules to a very limited level.
