Prothrombin Ab IgA ELISA Kit

  • Created on the 16 June, 2017.


Human prothrombin IgA ELISA kit is an in-vitro quantitative method for detecting levels of IgA auto-antibodies to prothrombin Ab (anti-prothrombin-IgA) in human plasma and serum. This assay has a minimum analytical sensitivity limit of 1.0 U/ml.


Prothrombin is a carbohydrate-protein compound which is an important component of the process of blood clotting, it is essentially a glycoprotein that is present in the blood plasma. Prothrombin is converted to thrombin with the help of prothrombinase (factor X), thrombin then acts in order to transformed fibrinogen into fibrin. Platelets and fibrin are responsible for forming clots (this process is known as coagulation). Under normal circumstances, fibrin and blood clots are only formed in response to bleeding. A deficiency in prothrombin (called hypoprothrombinemia) is defined by its prolonged bleeding tendency. The following prothrombin IgA ELISA kit can be used for a variety of diagnostic applications.


The minimum detection sensitivity level of IgA antibodies to human prothrombin (anti-prothrombin-IgA) using current human prothrombin IgA ELISA kit was 1.0 U/ml. The dynamic range for this assay is 6.3 – 100.0 U/ml.

Your secretory IgA ELISA 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 assay performed well and I was happy with the results that were generated.

I carried out a pilot study comparing the performance of many ELISA assay's 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. You have such an easy and simple system, yet it is very effective.
