APOBR ELISA kits are immunoassay tools for the measurement of the protein apolipoprotein B receptor, which is encoded by the APOBR gene in humans. Functionally, this protein is reported to be a macrophage receptor that binds to the apolipoprotein B48 (APOB) of dietary triglyceride (TG)-rich lipoproteins (TRL) or to a like domain of APOB in hypertriglyceridemic very low density lipoprotein (HTG-VLDL). The canonical protein structure is reported to have an amino acid sequence of 1097 residues and a mass of 115.6 kDa. It is known to be localized in the cell membrane and is reported to be expressed in peripheral blood leukocytes > bone marrow = spleen > lymph node, and only faintly visible in appendix and thymus. As many as 3 protein isoforms have been reported. Other alias names for this target include apolipoprotein B-100 receptor, apolipoprotein B-48 receptor, apolipoprotein B100 receptor, apolipoprotein B48 receptor, and apoB-48R.
The detection range for different APOBR ELISA kits can vary, with some assays measuring target concentrations as low as 0.156 ng/mL and as high as 100 ng/mL. Click on the products below for more detailed ELISA kit information, such as target reactivity and assay sensitivity.
