Our Abpromise guarantee covers the use of ab38987 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||1/1000 - 1/5000. Detects a band of approximately 23 kDa (predicted molecular weight: 26 kDa).
Recommended starting dilution of 1/1000 when using colorimetric substrates such as BCIP/NBT and 1/5000 when using chemiluminescent substrates.
Predicted molecular weight: 26 kDa. When used against the reduced protein, ab38987 identifies bands at 23 and 29 kDa, representing the unglycosylated and glycosylated forms of TIMP4 respectively.
Treatment of cells with the phorbol ester TPA stimulates production of TIMP4 in some cell types but the low protein levels produced often require concentration of cell culture media to visualize the bands by Western Blotting. Dilution optimised using Chromogenic detection.
FunctionComplexes with metalloproteinases (such as collagenases) and irreversibly inactivates them by binding to their catalytic zinc cofactor. Known to act on MMP-1, MMP-2, MMP-3, MMP-7 and MMP-9.
Tissue specificityAbundant in heart and present at low levels in many other tissues.
Sequence similaritiesBelongs to the protease inhibitor I35 (TIMP) family.
Contains 1 NTR domain.

Predicted band size: 26 kDa
Observed band size: 25,45,66,97 kDa why is the actual band size different from the predicted?
Additional bands at: 20 kDa, 23 kDa (possible glycosylated form). We are unsure as to the identity of these extra bands.
