purity :
Greater than 95% as determined by reducing SDS-PAGE.
form :
Lyophilized from a 0.2 uM filtered solution of PBS, 1mM DTT, pH 7.4.
storage stability :
Lyophilized protein should be stored at -20 degree C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 2-8 degree C for 2-7 days. Aliquots of reconstituted samples are stable at -20 degree C for 3 months.
tested application :
ELISA (EIA),Western Blot (WB), SDS-PAGE, Mass Spectrometry (MS)
other info1 :
Directions for Use: Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 mug/ml. Dissolve the lyophilized protein in 1X PBS. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
other info2 :
Endotoxin: Less than 0.1 ng/ug (1 IEU/ug) as determined by LAL test.
products description :
Recombinant Human HP Protein is produced by our E Coli expression system and the target gene encoding Cys145-Asn406 is expressed with a 6His tag at the N-terminus.

ncbi summary :
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. The protein encoded also exhibits antimicrobial activity against bacteria. 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, Oct 2014]
uniprot summary :
HP: Haptoglobin combines with free plasma hemoglobin, preventing loss of iron through the kidneys and protecting the kidneys from damage by hemoglobin, while making the hemoglobin accessible to degradative enzymes. Defects in HP are the cause of anhaptoglobinemia (AHP). AHP is 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. Belongs to the peptidase S1 family. Protein type: Endoplasmic reticulum; Secreted; Secreted, signal peptide. Chromosomal Location of Human Ortholog: 16q22.2. Cellular Component: extracellular region; extracellular space. Molecular Function: hemoglobin binding; protein binding. Biological Process: defense response; negative regulation of oxidoreductase activity; receptor-mediated endocytosis; response to hydrogen peroxide. Disease: Anhaptoglobinemia
