Lyophilized Standard Mix-Human Group 8, Panel A, 7-Plex. PN: HG81007. One vial containing lyophilized recombinant BMP-2, BMP-4, IGFBP-3, IGFBP-5, IGFBP-6, TIMP-1, and TIMP-2.  Note: If multiple analyte kits on the above target list are ordered as a panel, only one vial of standard mix is supplied for those analyte kits.

Application: Optimal antibody pair and antigen standard for assaying human Human TIMP-2. Can be multiplexed with other analytes in Human Group 8.  To be used in conjunction with the AimPlex NR Basic Kit (PN: P100001) and a diluent kit. Refer to the AimPlex Multiplex Immunoassay User Manual and kit inserts for the assay procedure.

Storage:  2-8 C in the dark.

Important: Sodium azide forms explosive compounds with heavy metals. These products contain <0.05% (w/w) azide which with repeated contact with lead and copper commonly found in plumbing drains may result in the buildup of shock sensitive compounds. Dispose in accordance with regulations from your institute.

Description:

TIMP metallopeptidase inhibitor 2 (TIMP-2), also known as TIMP2, is a human gene, thought to be a metastasis suppressor. TIMP-2 is a member of the TIMP gene family, which are natural inhibitors of the matrix metalloproteinases, a group of peptidases involved in degradation of the extracellular matrix. In addition to an inhibitory role against metalloproteinases, the encoded protein has a unique role among TIMP family members in its ability to directly suppress the proliferation of endothelial cells. TIMP-2 functions as both an MMP inhibitor and an activator. TIMPs inhibit all active MMPs, but different TIMPs inhibit different MMPs better than other TIMPs. For example, TIMP-1 inhibits MMP-7, MMP-9, MMP-1 and MMP-3 better than TIMP-2, and TIMP-2 inhibits MMP-2 more effectively than other TIMPs. In melanocytic cells TIMP2 gene expression may be regulated by MITF. Diseases associated with TIMP1 include oral submucous fibrosis and Sorsby Fundus Dystrophy.
