ARA Antibodies for Research Applications

Monoclonal antibodies directed against tissue inhibitor of matrix metalloproteinase-2 (TIMP-2)

Hybridoma Clone    Antibody Isotype    Cat. No
3A4                      Mouse IgG2a           ARA34

The 3A4 monoclonal antibody was generated from mice immunized with an 11 mer-peptide derived from the sequence of human TIMP-2. The amino acid sequence of this peptide was: DSGNDIYGNPI (Murray et al., 1998).

This monoclonal antibody binds to human TIMP-2. Reactivity in other species has not been determined, but the 11-mer peptide used for the immunization shows a 100% match with rat, mouse, and rabbit TIMP-2. The antibody was tested for cross-reactivity with TIMP-1 and did not cross-react.

Technical information
The 3A4 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.
