Applications

Recommended Concentration

Sample

ELISA

This antibody functions as an ELISA capture antibody when paired with Goat Anti-Human alpha ₂‑Macroglobulin Biotinylated Antigen Affinity-purified Polyclonal Antibody (Catalog # BAF1938).

This product is intended for assay development on various assay platforms requiring antibody pairs. We recommend the Human alpha 2-Macroglobulin DuoSet ELISA Kit (Catalog # DY1938) for convenient development of a sandwich ELISA.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Human alpha ₂‑Macroglobulin ELISA Standard Curve. Recombinant Human alpha ₂‑Macroglobulin protein was serially diluted 2-fold and captured by Mouse Anti-Human alpha ₂‑Macroglobulin Monoclonal Antibody (Catalog # MAB19381) coated on a Clear Polystyrene Microplate (Catalog # DY990). Goat Anti-Human alpha ₂‑Macroglobulin Biotinylated Antigen Affinity-purified Polyclonal Antibody (Catalog # BAF1938) was incubated with the protein captured on the plate. Detection of the standard curve was achieved by incubating Streptavidin-HRP (Catalog # DY998) followed by Substrate Solution (Catalog # DY999) and stopping the enzymatic reaction with Stop Solution (Catalog # DY994).

Background: alpha 2-Macroglobulin

Alpha 2-macroglobulin (A2M) is a general and irreversible protease inhibitor implicated in many processes. It is able to inhibit all four classes of proteases by a unique trapping mechanism.
