Beta-2 Glycoprotein I Screen ELISA Kit

  • Created on the 26 May, 2017.


Human beta-2 glycoprotein 1 screen ELISA kit is designed to screen in vitro quantitative levels of IgM, IgA and IgG auto-antibodies to beta2-glycoprotein I (apolipoprotein H, beta-2 GP1, ApoH) in human serum and plasma samples. This assay has a minimum analytical sensitivity limit of 0.5 U/ml.


Beta-2 glycoprotein 1 (also called beta-2 GP1, apolipoprotein H, ApoH) can be synthesised by endothelial cells, trophoblast cells and hepatocytes. It is a 326 amino acid polypeptide which consists of 5 homologous domains that are each approx. 60 amino acids. Beta-2 GP1 antibodies are found in patients which have antiphospholipid syndrome (APS), this condition has been linked to many clinical symptoms such as pregnancy complications, thrombocytopenia, thrombosis, systemic rheumatic diseases, hemolytic anemia, nonbacterial thrombotic endocarditis and unexplained cutaneous circulatory disturbances. In clinical research auto-antibodies to beta-2 GP1 antibodies can be identified using many different types of assays for example functional coagulation assays and immunoassays. The following beta-2-glycoprotein 1 screen ELISA kit can be used to determine different classes of these auto-antibodies (IgM, IgG and IgA).


The minimum detection sensitivity level of human beta-2 GP1 screen (IgA, IgM or IgG) using current human beta-2 glycoprotein 1 screen ELISA kit was 0.5 U/ml. The dynamic range for this assay is 3.3 – 90.0 U/ml.

Your secretory IgA ELISA kit gave good results and I was also really impressed with how quickly we received it.

It is refreshing to know that you have a technical team that is very knowledgeable. I have already recommended your company to other researchers in our department.

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA kit performed well and I was happy with the results that were generated.

I carried out a pilot study comparing the performance of many ELISA kits from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.

You are my first point of contact when I am looking to purchase ELISA kits. You have such an easy and simple system, yet it is very effective.
