MBS564072 is a ready-to-use microwell, strip-or-full plate ELISA (enzyme-linked immunosorbent assay) Kit for analyzing the presence of the Mouse Hemopexin (HPX) ELISA Kit target analytes in biological samples. The concentration gradients of the kit standards or positive controls render a theoretical kit detection range in biological research samples containing HPX. The ELISA analytical biochemical technique of the MBS564072 kit is based on HPX antibody-HPX antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect HPX antigen targets in samples. The ELISA Kit is designed to detect native, not recombinant, HPX. Appropriate sample types may include undiluted body fluids and/or tissue homogenates, secretions. Quality control assays assessing reproducibility identified the intra-assay CV (%) and inter-assay CV(%).

Principle of the Assay: The principle of the double antibody sandwich ELISA is represented in Figure 1. In this assay the Hemopexin present in samples reacts with the anti-Hemopexin antibodies which have been adsorbed to the surface of polystyrene microtitre wells. After the removal of unbound proteins by washing, anti-HX antibodies conjugated with horseradish peroxidase (HRP), are added. These enzyme-labeled antibodies form complexes with the previously bound HX. Following another washing step, the enzyme bound to the immunosorbent is assayed by the addition of a chromogenic substrate, 3,3',5,5'-tetramethylbenzidine (TMB). The quantity of bound enzyme varies directly with the concentration of HX in the sample tested; thus, the absorbance, at 450 nm, is a measure of the concentration of HX in the test sample. The quantity of HX in the test sample can be interpolated from the standard curve constructed from the standards, and corrected for sample dilution.

Background: Hemopexin (HX) is the plasma protein with the highest binding affinity to heme among known proteins. It is mainly expressed in liver and belongs to acute phase reactants, the synthesis of which is induced after inflammation. This ELISA kit can be used to measure Hemopexin in serum, tissue extracts and other biological fluids.

NCBI Summary for HPX
This gene encodes a plasma glycoprotein that binds heme with high affinity. The encoded protein is an acute phase protein that transports heme from the plasma to the liver and may be involved in protecting cells from oxidative stress. [provided by RefSeq]

Research Articles on HPX
1. Results indicate that for the discrimination of AD from ND control subjects, measurement of a set of markers including Abeta1-42, ApoA1 and HPX improved diagnostic performance over that obtained by measurement of Abeta1-42 alone.
2. In a family with a hypomaturation-type enamel defect, mutational and haplotype analyses revealed an amelogenesis imperfecta-causing point mutation in exon 6 of MMP20 that results in a single amino acid substitution in the hemopexin domain.
3. these observations result from the binding of heme in form beta with an orientation that differs from the crystallographically observed binding orientation for rabbit hemopexin
4. The structural consequences of metal ion binding to the form of hemopexin that dominates in plasma have been evaluated.
5. Hemopexin in minimal change nephropathy relapse subjects may exist in an altered isoform, showing enhanced protease activity as compared with subjects in remission, subjects with other forms of primary glomerulopathy, or healthy controls.
6. HPX-heme(II)-NO appears to act as an efficient scavenger of peroxynitrite and of strong oxidants and nitrating species following the reaction of peroxynitrite with CO2
7. The conserved binding ability of the Hemopexin domains suggests that CD44 may act as a core molecule assembling multiple Membrane-type 1 matrix metalloproteinases on the cell surface.
8. Thermal denaturation of the human hemopexin-heme complex is investigated under a variety of solution conditions to identify factors that influence heme release, including the potential presence of transition metal ions or heme iron reduction.
9. The ability of hemopexin to bind metal ions raises the possibility that this protein may participate in the transport of metal ions in blood or in the exchange of metal ions between proteins.
10. Hemopexin and hemopexin domains of human proteins fulfill functions in activation of MMPs, inhibition of MMPs, dimerization, binding of substrates or ligands, cleavage of substrates, and endocytosis by LRP-1 and LRP-2.
11. hemopexin molecule as such can potentially act as a toxic protease, leading to proteinuria and glomerular alterations
