No significant cross-reactivity or interference between Bovine HP and analogues was observed.

Store all reagents at 2-8 degree C

Samples: Serum, Plasma, Tissue Homogenate, Feces, Urine and Body Fluids. Intended Uses: This Quantitative Sandwich ELISA kit is only for in vitro research use only, not for drug, household, therapeutic or diagnostic applications! It is intended to be determinated HP concentrations in Bovine serum, plasma and other body fluids. Using Purified Bovine HP antibody to coat Microelisa Stripplate wells to make solid-phase antibody, then add HP and HP antibody which has been labeled with HRP to wells, then the reactants become antibody-antigen-antibody-enzyme complex, after washing completely, add TMB substrate solution, TMB substrate becomes blue color under HRP enzyme-catalyzed, reaction is terminated by the addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm. The concentration of HP in the samples is then determined by comparing the O.D. of the samples to the standard curve. Detection Range: The detection range of this kit is 25mug/ml-800mug/ml.

Sensitivity: The sensitivity of this kit is 5.0mug/ml. Intra-assay Precision: Intra-assay CV (%) is less than 15%. Inter-assay Precision: Inter-assay CV (%) is less than 15%. [CV(%) = SD/mean ×100]

This gene encodes a preproprotein, which is processed to yield both alpha and beta chains, which subsequently combine as a tetramer to produce haptoglobin. Haptoglobin functions to bind free plasma hemoglobin, which allows degradative enzymes to gain access to the hemoglobin, while at the same time preventing loss of iron through the kidneys and protecting the kidneys from damage by hemoglobin. Mutations in this gene and/or its regulatory regions cause ahaptoglobinemia or hypohaptoglobinemia. This gene has also been linked to diabetic nephropathy, the incidence of coronary artery disease in type 1 diabetes, Crohn's disease, inflammatory disease behavior, primary sclerosing cholangitis, susceptibility to idiopathic Parkinson's disease, and a reduced incidence of Plasmodium falciparum malaria. A similar duplicated gene is located next to this gene on chromosome 16. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

Function: As a result of hemolysis, hemoglobin is found to accumulate in the kidney and is secreted in the urine. Haptoglobin captures, and combines with free plasma hemoglobin to allow hepatic recycling of heme iron and to prevent kidney damage. Haptoglobin also acts as an Antimicrobial; Antioxidant, has antibacterial activity and plays a role in modulating many aspects of the acute phase response. Hemoglobin/haptoglobin complexes are rapidely cleared by the macrophage CD163 scavenger receptor expressed on the surface of liver Kupfer cells through an endocytic lysosomal degradation pathway. Ref.27Uncleaved haptoglogin, also known as zonulin, plays a role in intestinal permeability, allowing intercellular tight junction disassembly, and controlling the equilibrium between tolerance and immunity to non-self antigens. Ref.27. Subunit structure: Tetramer of two alpha and two beta chains; disufide-linked. The Hemoglobin/haptoglobin complex is composed of a haptoglobin dimer bound to two hemoglobin alpha-beta dimers. Interacts with CD163. Subcellular location: Secreted. Tissue specificity: Expressed by the liver and secreted in plasma. Polymorphism: In the human populations there are two major allelic forms, alpha-1 (1-1) with 83 residues and alpha-2 (2-2) with 142 residues. These alleles determine 3 possible genotypes, homozygous (1-1 or 2-2) and heterozygous (2-1), and 3 major phenotypes HP*1F/HP*1S and HP*2FS. The two main alleles of HP*1 are called HP*1F (fast) and HP*1S (slow). The alleles exhibit different oligomerization properties. In healthy males, but not in females, the Hp 2-2 phenotype is associated with higher serum iron, decreased Antimicrobial; Antioxidant capability, and less efficient clearance from the circulation, than Hp 1-1 and 2-1. Involvement in disease: Anhaptoglobinemia (AHP) [MIM:614081]: A condition characterized by the absence of the serum glycoprotein haptoglobin. Serum levels of haptoglobin vary among normal persons: levels are low in the neonatal period and in the elderly, differ by population, and can be influenced by environmental factors, such as infection. Secondary hypohaptoglobinemia can occur as a consequence of hemolysis, during which haptoglobin binds to free hemoglobin. Congenital haptoglobin deficiency is a risk factor for anaphylactic non-hemolytic transfusion reactions.Note: The disease is caused by mutations affecting the gene represented in this entry. Ref.28. Sequence similarities: Belongs to the peptidase S1 family.Contains 1 peptidase S1 domain.Contains 2 Sushi (CCP/SCR) domains. Caution: Although homologous to serine proteases, it has lost all essential catalytic residues and has no enzymatic activity.
