Thank you for your enquiry and your interest in our product.

We have already offered a testing discount for one of our customers who has tested ab2772 on mouse skin tissue sections. The results have been published as an Abreview and the image can be seen on the on-line datasheet. Since the rating of this feedback was only 3 star (and not 5 star), we are not convinced that ab2772 is suitable for detecting murine Prolactin Receptor antibody and have not updated the tested species section with mouse. We would still welcome more results from other customers.

Looking at this particular image, it seems that the background signal is pretty high. Since this primary antibody is raised in mouse and the samples are from the same species, it is likely that the antibody may recognize some endogenous non-specific immunoglobulins.

I could certainly offer you a discount code for testing but it would be worth perhaps considering using a mouse-blocking to reduce any potential high background signal.

The Terms and Conditions of the testing discount be found at: https://www.abcam.com/collaborationdiscount.

Please do let me know and confirm if you understand the conditions and wish to proceed with the testing.

I look forward to hearing from you soon.

Thank you for your email. As a positive control I can recommend to use sections from breast, placenta, kidney, liveror pancreas. Indeed, the prolactin receptor is expressed in those tissues. (http://www.uniprot.org/uniprot/P16471) There should however also be an expression in the salivary gland, as seen on the datasheet of ab2772. We do have in our catalogue tissue slides which can be used as positive controls. I can for example recomend thehuman placenta ab4360 or the rat placenta ab4623. https://www.abcam.com/Placenta-human-normal-tissue-slides-ab4360.html (or use the following: https://www.abcam.com/Placenta-human-normal-tissue-slides-ab4360.html). https://www.abcam.com/Placenta-rat-normal-tissue-slides-ab4623.html (or use the following: https://www.abcam.com/Placenta-rat-normal-tissue-slides-ab4623.html). I am looking forward to hear back from you in order to be able to assist you better.

Thank you for contacting us. I am very sorry to hear you are experiencing difficulties with one vial of ab2772. We take product complaints very seriously, and investigate every product that we feel may not be performing correctly. Our products are covered by our guarantee. We will therefore look together through the protocol, and try to find a solution to the problem. If the vial would be faulty, we would replace it for you. In order to proceed, I am attaching our questionnaire so that we can gather further information regarding the samples tested and the protocol used. Once we receive the completed questionnaire, we will look at the protocol and see if there are any suggestions we can make that may improve the results. This information will also allow us to investigate this case internally and initiate additional testing where necessary. If the product is being used according to our Abpromise, we would be happy to replace or refund the antibody. I look forward to receiving your reply.

Thank you for contacting us. As shown on the Abreviews (feedback obtained from end users), the prolactin receptor antibody ab2772 has been successfully used in IHC-Fr on Mouse skin sections and in IHC-P on Human salivary gland sections fixed with paraformaldehyde : https://www.abcam.com/index.html?pageconfig=reviews&intAbID=2772 . For IHC-P, the antibody was used at a dilution 1/100, for 12 hours at 4°C. No antigen retrieval method was applied. Another positive control recommended for alternative prolactin receptor antibodies is breast carcinoma. I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

The following references cite detection of the long and short Prolactin receptor proteins using clone U5 (though not specifically Abcam's ab2772): Short Form (~40 kDa) AJP Endocrinol Metab Vol 287, E750-E757 Sept 2004. http://ajpendo.physiology.org/cgi/reprint/287/4/E750 Detects short PRLR from mouse total liver lysates. Long Form (~100 kDa) J. Biol. Chem., 270(10):5136-5143, 1995. http://www.jbc.org/cgi/content/full/270/10/5136 Detects long PRLR from rabbit mammary gland membranes. I hope that this information is helpful. Please let me know if you have any additional questions.

Ab2773 has been shown to be specific for the short form around 42 kDa. The other Prolactin Receptor antibody that we currently have, ab2772, detects both the short and long forms. So unfortunately we don't have what your customer is looking for.
