Immunofluorescence analysis of COX-1 was performed using 70% confluent log phase MCF-7 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 COX-1 Rabbit Polyclonal Antibody (Product # PA5-16318) at 2µg/mL in 0.1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034) 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 Alexa Fluor® 555 Rhodamine Phalloidin (Product # R415, 1:300). Panel d represents the merged image showing cytoplasmic localization. Panel e shows the no primary antibody control. The images were captured at 60X magnification.

PA5-16318 targets COX-1 in IHC (P) applications and shows reactivity with Human samples.
The PA5-16318 immunogen is synthetic peptide corresponding to C-terminal of human COX-1.
Cyclooxygenases 1 and 2 (COX-1, COX-2) are enzymes involved in the conversion of arichidonate to prostaglandins. COX-1 and COX-2 are very similar in structure and function, though they vary in expression. COX-1 is normally expressed in most cell types, whereas COX-2 expression is at low levels unless induced by hormonal stimuli. In some breast cancer and bladder carcinoma studies, COX-1 was expressed in the stroma cells adjacent to the tumors but not in tumor cells.
