Recombinant Rat TIMP-1

Tissue Inhibitor of Metalloproteinases 1, also known as TIMP1 is a widely expressed, secreted protein that functions primarily to inhibit members of a large family of metalloproteinases (MPs). Because of the ability of TIMP-1 to inhibit MPs, it functions in many of the same pathophysiological processes as these enzymes, e.g. wound healing, ovulation, angiogenesis, and cancer cell metastasis. TIMP-1 can also stimulate proliferation and cellular anabolic processes.¹ TIMP-1 is a novel negative regulator of HGF activity during liver regeneration.² Overexpression of TIMP-1 could promote renal interstitial fibrosis through the inflammatory pathway, which might be partly induced by upregulating ICAM-1.³

Lyophilized

The predicted molecular weight of Recombinant Rat TIMP-1 is Mr 21.5 kDa. However, the actual molecular weight as observed by migration on SDS-PAGE is Mr 32-34 kDa.

21.5

This recombinant protein was 0.2 µm filtered and lyophilized from a sterile solution containing 10mM Tris, 75 mM NaCl pH 7.5.

This lyophilized protein is stable for six to twelve months when stored desiccated at -20°C to -70°C. After aseptic reconstitution, this protein may be stored at 2°C to 8°C for one month or at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. See Product Insert for exact lot specific storage instructions.
