| Tissue Specificity |
This antibody reacts with the three types of human haptoglobin (types 1-1, 2-1, and 2-2). In an ELISA, the antibody recognizes human haptoglobin as the purified antigen, in human serum, when complexed with human hemoglobin or captured by antibodies. In a competitive ELISA it does not cross react with human IgG, transferrin, C-reactive protein, alpha 1 acid glycoprotein, albumin or hemoglobin, nor with bovine, goat or sheep serum. The antibody reacts against native and denatured (non-reduced) human haptoglobin in an immunoblot or dot blot but fails to recognize the different haptoglobin types under reducing conditions. |
