Protein solutions are used for blocking excess binding sites in ELISA, blotting, immunohistochemistry and other immunochemical applications. Each blocking solution will impart certain characteristics ..
Enzyme-Linked Immunosorbent Assay (ELISA) is a useful, highly sensitive and powerful technique for the detection of proteins, chemicals, and drugs (antigens) in biological samples, including serum, bl..
A major drawback of current blocking solutions, such as BSA, casein and milk powder, is that they are derived from animal sources. The presence of animal proteins can often lead to high non-specific b..
Recombinant streptavidin from streptomyces avidinii, produced in E.coli. Biotin, a 244Da vitamin (Vitamin H) molecule, exhibits an extraordinary binding affinity for streptavidin (Ka=1015M-1). Biotin..
