Scientific Background
Human TIMP2/TIMP-2 Protein — also known as CSC-21K; DDC8; Metalloproteinase Inhibitor 2; Tissue Inhibitor of Metalloproteinases 2 — Tissue inhibitors of metalloproteinases (TIMP) family are natural inhibitors of the matrix metalloproteinases (MMPs), the zinc enzymes involved in extracellular matrix maintenance and remodeling. The TIMP family encompasses four members (TIMP1-4), and they inhibit most MMPs by forming non-covalent binary complex. TIMP2 is a 22 kDa non N-glycosylated protein expressed by a variety of cell types, and plays a unique role among TIMP family members owing to its functions to regulate cellular responses to growth factors. Findings establish an unexpected, MMP-independent mechanism for TIMP2 inhibitio
Research into Human TIMP2/TIMP-2 Protein supports investigations in tumor biology and oncology signaling, with implications for oncology signaling.

This protein is produced in HEK293 mammalian cells. Mammalian expression preserves glycosylation and folding closest to the native protein, supporting biological activity in cell assays.
Purity: > 96% as determined by reducing SDS-PAGE., confirmed by reducing SDS-PAGE. Endotoxin level: < 1.0 EU per μg of the protein as determined by the LAL method., measured by LAL assay — critical for cell-based studies. Identity is verified by peptide mapping or N-terminal sequencing on request.
Yes — biological activity is confirmed per lot. Activity data: Measured by its ability to inhibit human MMP-2 cleavage of a fluorogenic peptide substrate MCA-PLGL-DPA-AR-NH2(R&D Systems, Catalog # ES001). The IC50 value is < 4 nM.. Run a titration in your own system to establish optimal working concentration before committing all samples.
Reconstitution: Please refer to the printed manual for detailed information.. Storage: Generally, lyophilized proteins are stable for up to 12 months when stored at -20 to -80℃. Reconstituted protein solution can be stored at 4-8℃ for 2-. Avoid repeated freeze-thaw — each cycle risks partial denaturation.
This protein is validated for ELISA, Functional Assay (In Vitro). It is commonly used as an ELISA standard, binding partner in SPR/BLI, or stimulant in cell-based functional assays. Validate performance in your specific format before use in critical experiments.
