UltraAvidin™- DyLight® 405

UltraAvidin is Leinco Technologies' trademark for a uniquely modified form of avidin which is isolated from chicken egg whites.

With a molecular weight of 60,000 there are four identical subunits each capable of binding one molecule of biotin.

UltraAvidin from Leinco Technologies has been de-glycosylated to prevent carbohydrate moieties from adhering to lectin-like receptors on the surface of cells, thus eliminating the possibility of false positives.

Unlike native avidin, UltraAvidin has a near neutral pI which prevents electrostatic interactions with negatively charged serum or membrane proteins.
