General description
α2-Macroglobulin belongs to the macroglobulin superfamily. It is a high molecular weight tetrameric glycoprotein with receptor-binding domain (RBD), thioester-containing domain (TED) domain and C1r/C1s, Uegf, Bmp1 (CUB) domain.
Application
α2-Macroglobulin has been used as a component of homogenization buffer for processing hemibrains of young mice.
Biochem/physiol Actions
α2-Macroglobulin (α2M) binds several hormones and may regulate their activity. α2M also aids protection against various infections.
α2-Macroglobulin is a plasma endopeptidase and glycoprotein which functions on proteinases, especially serine proteases. It interacts with and inhibits endopeptidases. However, it does not act on other proteases, including inactive proteinases.
Preparation Note
Working solution: Recommended solvent is distilled water.
Storage conditions (working solution): -15 to -25 °C
Storage conditions (working solution): -15 to -25 °C
Soluble in water. Stable for at least one week at room temperature (15 to 25 °C), or 3 weeks at 2 to 8 °C. Can also be frozen in aliquots at -15 to -25 °C, where it remains stable for at least 6 months. Sensitive to acidic pH, denatured below pH 4.0. Ammonia methylamine and hydroxylamine (above pH 7.0) cause irreversible conversion to the inactive form.
Note: Do not use α2-macroglobulin in the presence of DTT since it causes a (reversible) dissociation into inactive subunits. α2-macroglobulin acts by physically entrapping endoproteinases, usually in a 1:1 ratio.

Store at 2 to 8 °C. (Store dry!)
Analysis Note
Specific activity: approximately 1 inhibitor U/mg protein (tested with trypsin at +25°C and Chromozym TRY as substrate).
Crossreactivity with pregnancy associated glycoproteins: deglycosylation of α2-macroglobulin is recommended.
Other Notes
α2-macroglobulin, a glycoprotein, is a tetramer of identical subunits, which are Iinked in pairs by disulfide bonds.

Alpha macroglobulins are large glycoproteins which are present in the body fluids of both invertebrates and vertebrates. Alpha-2-macroglobulin (α2 M), a key member of alpha macroglobulin superfamily, is a high-molecular weight homotetrameric glycoprotein. α2 M has many diversified and complex
