Background Information
PTGR1(Prostaglandin reductase 1) is also named as LTB4DH(NADP-dependent leukotriene B4 12-hydroxydehydrogenase) and belongs to the NADP-dependent oxidoreductase L4BD family. It catalyses the conversion of leukotriene B4 into biologically less reactive 12-oxo-leukotriene B4, a key step for its inactivation and it is a key oxidation step in the process of metabolic inactivation of leukotriene B(4) in various non-leukocyte tissues(PMID:8576264).

Reviews
What customers say
All five reviews are 5-star, focused on Western Blot performance. Users report the antibody works reliably with no background or non-specific bands, including as a positive control in HeLa cells. One reviewer validated the band via siPTGR1 knockdown in melanoma cells. Multiple users note consistent blotting at a 1:1000 dilution across cancer cell lines, with one high-throughput lab confirming no issues over repeated use. Overall, customers describe it as a dependable, highly recommended reagent for Western blot applications.

Kristen (Verified Customer) (12-15-2025) | Used as positive control (known to be expressed in HeLa cells), no background/non-specific bands seen
|
Casey (Verified Customer) (12-02-2025) | This antibody worked really well. Band was validated with siPTGR1 Knockdowns.
|
Haley (Verified Customer) (11-25-2025) | Highly recommended
|
Jelan (Verified Customer) (10-31-2025) | We use this antibody for completing our western blots, and we are a big lab who do westerns alot and we have not had any issues with this specific protein and it seems to be blotting fine.
