b2-Glycoprotein-1 (APO-H) Polyclonal Antibody – HRP Conjugated
Affinity’s b2-Glycoprotein-1 (APO-H) Polyclonal Antibody – HRP Conjugated is the base level of our horseradish peroxidase conjugated b2-Glycoprotein-1 (APO-H) antibodies. The purity of IgG is typically 90% and is provided in a solution of HEPES buffered saline containing 50% glycerol (v/v). The titre is essentially the same as the starting antiserum and each vial typically contains the amount of IgG recovered from one milliliter of antiserum however this IgG has been conjugated with Horseradish Peroxidase as an enzyme reporter. This b2-Glycoprotein-1 (APO-H) Polyclonal Antibody – HRP Conjugated is generally intended for use as labeled primary antibodies in applications such as immunoassay and immunoblotting.

Description of Beta-2-Glycoprotein-1 (Apolipoprotein-H, APOH)
Beta-2-Glycoprotein 1 (B2GP1), also known as Apolipoprotein-H (APOH), is a plasma glycoprotein that circulates at a concentration of 200 ug/ml (4 μM). Synthesized in the liver, β2GP1 is a single chain molecule of 48 kDa, consisting of five repeating internally disulphide-bonded structures referred to as sushi domains. Relative to other glycoproteins, β2GP1 has an unusually high content of cysteine (6.2%), proline (8.3%) and carbohydrate (19%). Almost half the circulating β2GP1 in plasma is associated with lipoproteins of all major fractions. β2GP1 has been demonstrated to bind negatively charged phospholipids, heparin and platelets. Although the precise function(s) are as yet unknown, β2GP1 has been demonstrated to interfere with blood coagulation by competitively binding to negatively charged phospholipid surfaces exposed during cell activation or damage. Recent evidence also implicates β2GP1 as a cofactor recognized by anti-phospholipid antibodies present in some autoimmune disorders such as systemic lupus erythematosus (SLE)1-3.
