| HAPO-H - Apolipoprotein-H Apolipoprotein-H (B2GP-1) |
£
price not available in open catalogue/0.1 mg |
B2Glycoprotein-1 (B2GP-1), also known as Apolipoprotein-H is a plasma glycoprotein that circulates at a concentration of 200 ug/ml (4 uM). B2GP-1 has been identified as a constituent of chylomicrons, very low density lipoproteins and high density lipoproteins in human plasma. It has also been demonstrated to bind phospholipids, heparin and platelets where it can modulate the activity of adenylate (19%).
Although the precise function(s) are as yet unknown, B2GP-1 has been shown to interfere with blood coagulation by competitively binding to phospholipids exposed during cell activation or damage. Recent evidence also implicates B2GP-1 as a cofactor recognized by some anti-phospholipid antibodies present in autoimmune disorders such as systemic lupus erythematosus (SLE).

| P1FIB Peak'1' Purified Fibrinogen |
£
price not available in open catalogue/50.0 mg |
| Contains mostly intact Aα subunit chains, is free of plasminogen, factor XIII, fibronectin, and other non-fibrinogen protein contaminants. Peak'1'fibrinogen molecules each contain two copies of the platelet-binding γA chain C-terminal sequence and are ideal substrates for factor XIII assay. |

| P2FIB Peak'2' Purified Fibrinogen |
£
price not available in open catalogue/50.0 mg |
| Contains measurable amonts of factor XIII activity because the factor XIII B subunits bind to the γ chains and bring catalytic A subunits along with them. Thus Peak'2' fibrinogen serves as a 'carrier'for factor XIII in blood. The γ chain lacks the platelet recognition sequence but, becomes crosslinked to dimers by factor XIIa. |

α2-Antiplasmin (α2AP), also known as α2Plasmin Inhibitor, is a plasma glycoprotein that is a member of the SERPIN family of proteinase inhibitors. α2AP is the primary fast-acting inhibitor of plasmin in vivo, but has also been reported to inhibit other enzymes such as trypsin, elastase, and Activated Protein C. α2AP is purified from normal human plasma using immunoaffinity and ion-exchange chromatography. Purified α2AP activity is determined by titration with purified plasmin.
Buffer Composition = 20 mM Tris-HCl/0.15 M NaCl/pH 7.3
