The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
| Application | Abreviews | Notes |
|---|---|---|
| WB | 1/500 - 1/1000. Detects a band of approximately 72 kDa (predicted molecular weight: 69 kDa).Can be blocked with COX2 / Cyclooxygenase 2 peptide (ab213704). |
Target
-
Function
Mediates the formation of prostaglandins from arachidonate. May have a role as a major mediator of inflammation and/or a role for prostanoid signaling in activity-dependent plasticity. -
Pathway
Lipid metabolism; prostaglandin biosynthesis. -
Sequence similarities
Belongs to the prostaglandin G/H synthase family.
Contains 1 EGF-like domain. -
Post-translational
modificationsS-nitrosylation by NOS2 (iNOS) activates enzme activity. S-nitrosylation may take place on different Cys residues in addition to Cys-561. -
Cellular localization
Microsome membrane. Endoplasmic reticulum membrane. - Information by UniProt

identity of the extra band in HCT 116 and MCF7.
The expression profile observed in HCT 116 and MCF7 are consistent with the literatures (PMID: 14739610, PMID: 24325753, PMID: 16997132).
