  • Function

    Receptor for prostaglandin E2 (PGE2); the EP3 receptor may be involved in inhibition of gastric acid secretion, modulation of neurotransmitter release in central and peripheral neurons, inhibition of sodium and water reabsorption in kidney tubulus and contraction in uterine smooth muscle. The activity of this receptor can couple to both the inhibition of adenylate cyclase mediated by G-I proteins, and to an elevation of intracellular calcium. The various isoforms have identical ligand binding properties but can interact with different second messenger systems.
  • Tissue specificity

    Expressed in small intestine, heart, pancreas, gastric fundic mucosa, mammary artery and pulmonary vessels.
  • Sequence similarities

    Belongs to the G-protein coupled receptor 1 family.
  • Cellular localization

    Cell membrane.

Thank you for contacting us yesterday and I am sorry for the delay in getting back to you.

As discussed over the phone, I have had a look into how much peptide we would suggest using in the blocking experiment you are planning. As I mentioned over the phone, we have as yet not used the antibody ab94496 in IHC and I therefore cannot recommend from a protocol we have used. What I can say is that we would typically work from a 200 fold molar excess of peptide when using it for Western blotting blocking. For this peptide, this would mean using 32 µg/mL for your experiment (assuming you are using a 1/250 dilution, 4 µg/mL). As you mentioned over the phone, this is quite a large proportion of the whole ab151180 product. I would say that a 50 molar excess should be enough for the blocking, so using 8 µg/mL. However, as I have mentioned, we have not tried it ourselves and would therefore not be able to guarantee it.

I'd like to provide you with an offer in order to make it a little less prohibitive in order to purchase another lot of blocking peptide. If you would agree to share the results you have obtained with ab94496 and ab151180 in IHC through submitting an Abreview, I can offer to provide you with another vial of ab151180 for free (or for you to use the same value off any product in our catalogue, £113). An Abreview should not take very much time to complete, at most 5-10 minutes. An example of one can be viewed from the following link:


Let me know if you would be interested in this offer.

I am still looking into why you had to wait for almost a month for ab151180 to be shipped, and if this is likely to be the case if it is ordered again. I will get back to you as soon as I have further information to share with you.

I now have further information to share with you in regards to the anti-PTGER3 antibody (ab94496).

I can confirm that the delay in your previous order for the peptide was due to the peptide not being available in stock. It therefore had to be produced in order to fulfill your order. I am sorry for this delay and any inconvenience it has caused you. This would not be the case if you were to place an order in the near future as there is now units available directly in stock. We would estimate a delivery time of 2 weeks or less.

I hope this information has been of help. If I can be of any further assistance, please do not hesitate to ask.
