Specificity 

This antibody recognizes reduced TIMP1, but does not bind as well to the non reduced protein. It also does not cross react with other TIMP family members (TIMP2, TIMP3, TIMP4).

We have a range of domain specific antibodies for this target. For a full list please see all TIMP1 antibodies

Recommended dilutions
WB: Recommended starting dilution of 1/1000 when using colorimetric substrates such as BCIP/NBT and 1/5000 for chemiluminescent substrates. Detects a band of approximately 29 kDa when used against the reduced protein (predicted molecular weight: 23 kDa). Higher concentration of antibody may be needed for non human samples. Dilution optimised using Chromogenic detection. Not yet tested in other applications. Optimal dilutions/concentrations should be determined by the end user.

Positive control 
(see definition)

Cell media from human chondrosarcoma.

Relevance 

Tissue inhibitor of metalloproteinases 1 (TIMP1) and Tissue inhibitor of metalloproteinases 2 (TIMP 2) have similar properties, specifically in inhibiting enzymes of the matrix metalloproteinase family, and are thought to be of great importance in the maintenance of connective tissue integrity. TIMP1 forms a complex of 1:1 stoichiometry with activated interstitial collagenases, activated stromelysin, active form of 72kDa Type IV collagenase (also known as MMP2 or gelatinase A), and latent and active forms of 92kDa Type IV collagenase (also known as MMP0 or gelatinase B).

TIMPs inhibit the proteolytic invasiveness of tumour cells and normal placental trophoblast cells.

TIMP1 is produced in low (pg/ml) levels by most cell types. Treatment of cells with the phorbol ester TPA stimulates production of TIMP1 in some cell types, but the low protein levels produced often require concentration of cell culture media to visualize the bands by Western Blotting.
