Matched Antibody Pair Kits include a capture and a biotinylated detector antibody pair, along with a calibrated protein standard, suitable for sandwich ELISA. The Matched Antibody Pair Kit can be used to quantify native and recombinant Human Haptoglobin.
Matched antibody pair kits and reagents deliver consistent, specific, and sensitive results.
- Batch-to-batch consistency: only recombinant monoclonal antibodies are used in our matched antibody pairs.
- Specificity: antibody pairs are screened in plasma and serum to ensure specificity in complex samples.
- Sensitivity: benchmarked against commercially available antibody pairs to ensure equivalent or superior performance compared with the competition.
Additional buffers and plates are required for the assay. An accessory pack can be purchased which includes buffer reagents required to perform 10 x 96-well plate sandwich ELISAs (ab210905).
For additional information on the performance of the antibody pair used in this kit, please see our equivalent SimpleStep ELISA® (ab219048) which uses the same antibody pair.

FunctionAs 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.
Uncleaved 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.
Tissue specificityExpressed by the liver and secreted in plasma.
