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 antioxidant, has antibacterial activity and plays a role in modulating many aspects of the acute phase response. Hemoglobin/haptoglobin complexes are rapidly cleared by the macrophage CD163 scavenger receptor expressed on the surface of liver Kupfer cells through an endocytic lysosomal degradation pathway (By similarity).

Notes
Mouse Haptoglobin ELISA kit (ab272472) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of Mouse Haptoglobin protein in serum, urine, plasma and cell and tissue supernatant. It uses our proprietary SimpleStep ELISA® technology. Quantitate Mouse Haptoglobin with 3.91 pg/mL sensitivity.
SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:
-Single-wash protocol reduces assay time to 90 minutes or less
-High sensitivity, specificity and reproducibility from superior antibodies
-Fully validated in biological samples
-96-wells plate breakable into 12 x 8 wells strips
A 384-well SimpleStep ELISA® microplate (Pre-coated 384 well Microplate SimpleStep ELISA® ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.
Haptoglobin, encoded by the HP gene and produced mostly by hepatic cells, is a major acute phase protein. Haptoglobin is known to bind to free hemoglobin released from erythrocytes with high affinity and inhibits its oxidative activity to allow hepatic recycling of the heme iron. Biosynthesis of haptoglobin can also occur in adipose and lung tissues to provide antioxidant and antimicrobial activity. Studies have shown haptoglobin to play a role in stimulation of angiogenesis and changes in the measured concentrations in serum may associate with certain inflammations, infections, and hemolytic conditions. Human, rat, cow, monkey share 81%, 90%, 76%, and 80% sequence homology with mouse haptoglobin, respectively.

- Activity summary
Haptoglobin (Hp) also known as Hp protein is a glycoprotein with a molecular weight ranging from 85 to 100 kDa varying due to its ability to form different dimeric and multimeric structures. It is primarily synthesized in the liver and circulating in the plasma. Mechanically haptoglobin binds free hemoglobin released from erythrocytes preventing oxidative damage and hemoglobin-driven deleterious effects. Haptoglobin's binding to hemoglobin forms a haptoglobin-hemoglobin complex that gets cleared by the CD163 receptor on macrophages mainly in the liver and spleen.
- Biological function summary
Haptoglobin functions as an antioxidant and an acute phase protein playing roles in inflammation and immune response. It is an essential component of the antioxidant defense system reducing oxidative stress by binding free hemoglobin. Additionally haptoglobin can participate in complex formation with hemoglobin to facilitate the clearance of excess free hemoglobin from circulation. Its expression increases during inflammation under the regulation of cytokines like IL-6.
- Pathways
The haptoglobin protein is part of the hemoglobin clearance pathway integral for iron metabolism and homeostasis. This pathway ensures the safe removal of hemoglobin from the blood helping to prevent kidney damage. Haptoglobin is related to other proteins such as CD163 and the liver-derived hepatocellular proteins involved in the clearance process. Also haptoglobin is linked to antioxidant pathways collaborating with oxidative stress regulators to manage reactive oxygen species levels.
- Associated diseases and disorders
Changes in haptoglobin levels are associated with hemolytic anemia and inflammatory conditions. Low haptoglobin levels often suggest hemolytic anemia due to its rapid binding with free hemoglobin in the bloodstream. During inflammation and infections 'anti-Hp' tests (haptoglobin tests) may show increased haptoglobin levels as a response to cytokine signaling. Moreover haptoglobin polymorphisms have a connection with ischemic stroke susceptibility where its isoforms show differing efficiencies in binding free hemoglobin. These findings highlight haptoglobin's relevance as a biomarker for these conditions and illustrate its interaction with hematologic and immune proteins in disease contexts.

Sandwich ELISA - Mouse Haptoglobin ELISA Kit (ab272472)
Example of mouse Haptoglobin standard curve in Sample Diluent NS.
The Haptoglobin standard curve was prepared as described in Section 10. Raw data values are shown in the table. Background-subtracted data values (mean +/- SD) are graphed.
Sandwich ELISA - Mouse Haptoglobin ELISA Kit (ab272472)
Interpolated concentrations of native Haptoglobin in mouse serum and plasma samples.
The concentrations of Haptoglobin were measured in duplicates, interpolated from the Haptoglobin standard curves and corrected for sample dilution. Undiluted samples are as follows: serum 1:250,000, plasma (citrate) 1:1,000,000, plasma (EDTA) 1:250,000, and plasma (heparin) 1:250,000. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean Haptoglobin concentration was determined to be 271.1 μg/mL in serum, 836.8 μg/mL in plasma (citrate), 265.2 μg/mL in plasma (EDTA), and 282.0 μg/mL in plasma (heparin).
Sandwich ELISA - Mouse Haptoglobin ELISA Kit (ab272472)
Interpolated concentrations of native Haptoglobin in mouse tissue culture supernatant and urine samples.
The concentrations of Haptoglobin were measured in duplicates, interpolated from the Haptoglobin standard curves and corrected for sample dilution. Undiluted samples are as follows: liver supernatant 1:200 and urine 1:160. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean Haptoglobin concentration was determined to be 211.7 ng/mL in liver supernatant and 109.3 ng/mL in urine.
