Protein antigens

Whether natural or recombinant – purified proteins are pivotal in a range of applications, serving as essential components in assays and experimental protocols. In ELISA (Enzyme-Linked Immunosorbent Assay), they are frequently utilized as standards, providing a reference for quantifying antigen or antibody concentrations with high precision. In Western blotting, these proteins act as positive controls, ensuring the accuracy and reliability of the assay by confirming the specificity and efficacy of the antibodies used. Moreover, in the generation of antibodies, proteins serve as antigens, facilitating the production of antibodies with high specificity.
