Immunofluorescence analysis of TIMP2 was performed using 70% confluent log phase HT-1080 cells treated with Protein Transport Inhibitor (PTI; 1x for 4 hours). The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 15 minutes, and blocked with 1% BSA for 1 hour at room temperature. The cells were labeled with TIMP2 Recombinant Rabbit Monoclonal Antibody (Product # MA5-32632) at 1:100 dilution in 0.1% BSA, incubated at 4 degree Celsius overnight and then labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Recombinant Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034) 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 (Product # S36938). F-actin (Panel c: red) was stained with Rhodamine Phalloidin (Product # R415, 1:300). Panel d represents the merged image showing increased TIMP2 expression and localization to golgi and cytoplasm upon treatment with PTI. Panel e shows untreated cells with lower expression of TIMP2. Panel f represents control cells with no primary antibody to assess background. The images were captured at 60X magnification.
