Scientific Data Images for Human alpha2-Macroglobulin Antibody
Human alpha2-Macroglobulin ELISA Standard Curve.
Recombinant Human alpha2-Macroglobulin protein was serially diluted 2-fold and captured by Mouse Anti-Human alpha2-Macroglobulin Monoclonal Antibody (Catalog # MAB19381) coated on a Clear Polystyrene Microplate (Catalog # DY990). Goat Anti-Human alpha2-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).Applications for Human alpha2-Macroglobulin Antibody
Application
Recommended Usage
ELISA
This antibody functions as an ELISA capture antibody when paired with Goat Anti-Human alpha2‑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.

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.
