Product details:
Abcam's Hemopexin (HPX) Human
in vitro
ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of Hemopexin levels in Human CSF, milk, saliva and urine.
A Hemopexin specific antibody has been precoated onto 96-well plates and blocked. Standards or test samples are added to the wells and subsequently a Hemopexin specific biotinylated detection antibody is added and then followed by washing with wash buffer. Streptavidin-Peroxidase Conjugate is added and unbound conjugates are washed away with wash buffer. TMB is then used to visualize Streptavidin-Peroxidase enzymatic reaction. TMB is catalyzed by Streptavidin-Peroxidase to produce a blue color product that changes into yellow after adding acidic stop solution. The density of yellow coloration is directly proportional to the amount of Hemopexin captured in plate.
The entire kit may be stored at -20°C for long term storage before reconstitution - Avoid repeated freeze-thaw cycles.

Hemopexin also known as HPX is a glycoprotein that transports heme in the blood. It has a molecular weight of approximately 57 kDa and is primarily expressed in the liver. Hemopexin binds to free heme with high affinity which prevents oxidative damage and conserves iron. It transports the heme to hepatocytes for breakdown and recycling protecting cells from iron-mediated toxicity and oxidative stress.
Biological function summary
The hemopexin function relates to protecting tissues from the harmful effects of free heme. Hemopexin does not work as part of a complex in this process but mainly acts independently. Its high binding affinity plays an important role in maintaining heme homeostasis in the plasma and tissues. By controlling heme levels hemopexin supports overall cellular health and function.
Pathways
The hemopexin molecular weight allows it to fit effectively within the heme metabolism and iron recycling pathways. This protein plays a significant role by delivering heme to the liver and facilitating its degradation by heme oxygenase. Hemopexin interacts closely with heme oxygenase and albumin two proteins important for the management of heme and iron levels in the body.
Several hemopexin functions contribute to the understanding of conditions such as hemolytic anemia and acute liver injury. In hemolytic anemia hemopexin helps mitigate the effects of increased heme levels due to excessive red blood cell breakdown. In the context of liver injury the protein assists in the detoxification process and supports hepatic function. Hemopexin-related proteins such as heme oxygenase link these diseases to hemopexin by their roles in managing oxidative stress and heme catabolism.
