Beta 2 Microglobulin (B2MG) ELISA Kit

  • Created on the 22 March, 2017.


Beta 2 microglobulin (B2MG) is a 11 kDA protein that was originally identified as a small serum protein, this small size helps B2MG to pass through the glomerular membrane and it is also often completely reabsorbed in the proximal tubules. It is able to form the subunit of the MHC class I molecule and also be associated with many outer membrane of a number of cells which includes lymphocytes. It is usually is present in the subunit of class I major histocompatibility complex (MHC I) which can be found expressed on all nucleated cell except red blood cells. B2MG is also linked with MHC I-like molecules for example CD1 and Qa.

Generally it is present in minute amounts but tends to increase its expression or even adapt to the fibrillary configuration depending on certain pathological states. Often B2MG is present at low levels in the serum or urine of normal people, however these concentrations are much higher in patients having kidney transplants, renal diseases and various other infectious or inflammatory conditions. This immunoassay is an ideal tool for analysing the function and regulation of this protein.


Human beta 2 microglobulin ELISA kit can be used for determining in vitro quantitative amounts of beta(2)-microglobulin (B2MG) in human serum, cell culture supernatant and various other biological samples. This assay has a minimum detection limit of < 0.2 μg/mL.


The minimum detection sensitivity level human beta 2 microglobulin using this human human beta 2 microglobulin ELISA kit was 3.0 μg/mL. The dynamic assay range for this kit is 0.75 – 12.0 μg/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.
