High mobility group protein B1 (HMGB1) is described as a non-histone chromatin-linked protein that functions in stabilising nucleosomes and thereby regulating transcription. It is a highly conserved protein that is displays approx. 99% homology between humans and rodents, it is abundant within the nucleus and expressed ubiquitously. It is a member of the hsp70/hsp90 family and it is an integral part of the heat-shock protein (HSP) response. HMGB1 can be released from cells by necrosis, stress (heat, ultraviolet light and ionizing radiation), apoptosis and cell death.

When released in response to tissue injury or other factors, HMGB1 accumulates under the surface of the plasma membrane to create a soluble pro-inflammatory state. The gene encoding human HMGB1 has been identified as SCR2 and is located on chromosome 6. It is essentially a nuclear protein that predominately binds to nucleosomes in promoting bending of DNA. It has the ability to bind damaged and distorted DNA, this allows it to undertake a wide array of functions such as DNA repair, cytosolic DNA recognition and chromatin structure regulation.

There are many cancer cells that display up-regulation of HMGB1 expression, the metastatic potential of many tumor cells was shown to show a direct relationship with the expression. This could be due its ability in modulating the adhesion cells, angiogenesis and extracellular matrix. The protein is able to catalyze this reaction, which uses oxygen radicals as an electron source during catalysis. The other important role that it performs is the activation of neutrophils, which moves oxygen and hydrogen peroxide to any site of infection.


Human HMGB1 ELISA kit can determine concentrations of high mobility group protein B1 (HMGB1, HMG-1, amphoterin, high mobility group box 1, non-histone chromosomal protein-1) using human samples of plasma, other biological samples, serum and tissue homogenates.


All reagents supplied need to be stored at 2 °C – 8 °C, unopened reagents will retain reactivity until expiration date. Do not use reagents beyond this date.

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.

J. Thomas
Senior Technician / Addenbrooke’s Hospital

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.
