Background Information
Oxytocin (OXT) is a neurohypophysial hormone that plays a role in lactation and parturition and in the central nervous system as a neurotransmitter involved in sex and maternal behavior (PMID: 1852313; 10811917). OXT acts through its receptor, OXTR, which belongs to the G protein-coupled 7-transmembrane receptor family. OXTR is expressed in the endometrium, myometrium, and mammary gland (PMID: 1313946). This antibody is raised against the C-terminal region of human OXTR. Two immunoreactive OXTR bands were found in the fat tissue, an unglycosylated 43 kDa form and a mature glycosylated 67 kDa form (PMID:32819381).

Reviews
What customers say
The single review (3/5) reports mixed results on rat brain tissue. For Western Blot, the user experienced a weak peak with heavy background noise, preventing proper optimization and sample runs. Immunofluorescence also showed significant background staining. Overall, the reviewer found the antibody difficult to work with due to high background across applications.
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
Rachael (Verified Customer) (08-29-2025) | Ran it through the protein simple abby machine and the results was a weak peak with lots of background noise, which meant we couldn't optimise and run our samples. when using it in immunofluorescence there was a lot of background staining
