Background Information

PTGS1(Prostaglandin G/H synthase 1) belongs to the prostaglandin G/H synthase family and catalyzes the conversion of arachidonic acid to prostaglandin H2, which is subsequently metabolized to various biologically active prostaglandins. It is also named as COX1(Cyclooxygenase-1). There is no PTGS1 expression in fetal samples (prostate, seminal vesicles, or ejaculatory ducts), and only minimal expression in adult tissues (PMID: 10999846). PTGS1 has some isoforms with MW of 56-72 kD and PTGS1 can form homodimer.

HeLa cells were fixed in 4% PFA for 15 mins and permeabilised in 0.1% Triton-X 100 in PBS. Cells were blocked in 1% BSA. Primary antibody solution was diluted at 1:200 in blocking solution and incubated for 1 hour. Goat anti-rabbit 488 Alexa Fluor secondary antibody (1:250 - green) and DAPI (1:2000 - blue) were incubated with cells for 1 hour.
