ARA Antibodies for Research Applications

Monoclonal antibodies directed against tissue inhibitor of matrix metalloproteinase-1 (TIMP-1)

Hybridoma Clone    Antibody Isotype    Cat. No
2A5                        Mouse IgG1          ARA33

The 2A5 monoclonal antibody was generated from mice immunized with a 11 mer-peptide derived from the sequence of human TIMP-1. The amino acid sequence of this peptide was: FQALGDAADIR (Murray et al., 1998).

This monoclonal antibody binds to human TIMP-1. Reactivity in other species has not been determined. The 11-mer peptide used for the immunization differs on at least 3 amino acids with the sequence of TIMP-1 of rat, mouse, and rabbit. Therefore it is not expected to be effective in these species as well. The antibody was tested for cross-reactivity with TIMP-2 and did not cross-react.

Technical information
The 2A5 monoclonal antibody has been tested for use in Western blotting and immunohistochemical analysis of formalin-fixed/paraffin-embedded tissues. It is suggested to use colon carcinoma as positive control. Antigen retrieval by microwave treatment (5-20 min at full power, 950 W in 0.01 M sodium citrate buffer, pH 6.0) is recommended for immunohistochemical analysis.
