General description

Matrix metalloproteinase 9 (MMP-9), a member of the peptidase M10A family, is a multidomain zinc metalloproteinase enzyme, which is highly expressed in neurons and glia of the hippocampus, cerebral cortex, and cerebellum. The active MMP-9 is formed upon cell stimulation by enzymatic cleavage of the precursor, proMMP-9. Because of its function in tissue degradation, MMP-9 is tightly regulated by multiple mechanisms, including glycosylation, inhibition by TIMP1, internalization, and sequestration. MMP-9 plays an important role in long-term potentiation, synaptic plasticity, and memory. Several studies have reported an increase in levels of MMP-9 after CNS injury, as well during the development of various cancers.

Specificity

This antibody recognizes the N-terminus of MMP-9 (Active).

Immunogen

Epitope: N-terminus
Ovalbumin-conjugated linear peptide corresponding to the N-terminus of human MMP-9 (Active).

Application

MMPs & TIMPs
This Anti-MMP-9 (Active) Antibody, clone 4A3 is validated for use in Western Blotting, IHC for the detection of MMP-9 (Active).
Western Blot Analysis: A representative lot from an independent laboratory detected the active form of MMP-9 in WB (Duncan, M. E., et al. 1998. Eur J Biochem. 258(1):37-43).

Immunohistochemistry Analysis: A representative lot from an independent laboratory detected the active form of MMP-9 in oesophageal cancer tissues (Duncan, M. E., et al. 1998. Eur J Biochem. 258(1):37-43).

Quality

Evaluated by Western Blot with the active form of MMP-9.

Western Blot Analysis: A 1:250 dilution from a reprsentative lot detected the active form of MMP-9 in WB.

Target description

~67 kDa observed. Under reducing conditions in SDS-PAGE, MMP-9 monomer (proenzyme) is observed as a major band at ~ 92 kDa Activation of MMP-9 proenzyme with trypsin yields different active forms at ~64, ~67, and ~82 kDa in a time dependent manner (Duncan, M. E., et al. 1998. Eur J Biochem. 258(1):37-43).
