Avidin Protein, Hrp, Pack Of 1

Details:

Avidin from chicken egg whites is a glycoprotein that effectively binds biotin, a tag that is frequently used to tag antibodies and other probes for immunodetection methods. Pure avidin is a key component in certain immunohistochemistry (ihc) methods. Alkaline phosphatase (ap) and horseradish peroxidase (hrp) conjugates of avidin are useful for western blotting or elisa detection with appropriate enzyme substrates. Highlights:native avidin – glycoprotein from chicken egg whites, 67kda, pi equals 10soluble – glycosylation and isoelectric point renders avidin more soluble than streptavidinaffordable – significantly less expensive than recombinant streptavidinabc staining – avidin is usually preferred over streptavidin for avidin-biotin complex (abc) staining methods in immunohistochemistry (ihc)pure protein and conjugates – choose pure, unconjugated avidin for use in abc staining or peroxidase or alkaline phosphatase forms for membrane and plate-based assay
