Immunofluorescence analysis of TIMP1 was done on 70% confluent log phase HepG2 cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, and blocked with 1% BSA for 1 hour at room temperature. The cells were labeled with TIMP1 (F31 P2 A5) Mouse Monoclonal Antibody (MA1773) at 2ug/ml in 0.1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Mouse IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A28175) at a dilution of 1:2000 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (S36938). F-actin (Panel c: red) was stained with Alexa Fluor® 555 Rhodamine Phalloidin (Product # R415, 1:300). Panel d is a merged image showing cytoplasmic localization. Panel e is a no primary antibody control. The images were captured at 60X magnification.

MA1-773 contains 100 ug of in vitro produced, protein A purified antibody (1 mg/ml) in PBS containing 1 mg/ml BSA and 0.05% sodium azide.
MA1-773 detects TIMP-1 from human samples.
MA1-773 has been successfully used in Western blot, immunofluorescence, and immunohistochemistry procedures. By Western blot, MA1-773 detects a ~30 kDa band representing TIMP-1 from K562 cell lysate. It is recommended to block with 3% BSA.
The MA1-773 immunogen is a synthetic peptide corresponding to residues F(72) Q A L G D A A D I R(82) of mouse TIMP-1.This sequence is 100% conserved in some non-human primate TIMP-1.
Tissue inhibitor of metalloproteinases-1 (TIMP-1) and Tissue inhibitor of metalloproteinases-2 (TIMP-2) are inhibitory enzymes of matrix metalloproteinase family. TIMP-1 forms a complex of 1:1 stoichiometry with activated interstitial collagenase, activated stromelysin, active form of 72 kD Type IV collagenase (MMP-2) and latent and active forms 92 kD Type IV collagenase (MMP-9). TIMPs inhibit the proteolytic invasiveness of tumor cells and normal placental trophoblast cells.
