The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB Use a concentration of 0.5 - 1.25 µg/ml. Detects a band of approximately 28, 32, 85 kDa (predicted molecular weight: 28 kDa). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
ELISA Use at an assay dependent concentration.

ELISA titre using peptide based assay 1:312500.

IHC-P Use a concentration of 4 - 8 µg/ml.

Thank you for your reply and for your interest in ab66765. I will have the blocking peptide added to the catalog, and I'll let you know the catalog number once this is completed. Since ab66765 has not been tested in bovine or murine samples, if you would like to test it in one of these species, you are eligible for our testing discount program. For this program, you would purchase the antibody at full price, submit an Abreview with your data, and in exchange we will give you one free primary antibody on a future purchase (must be requested within 4 months of ab66765 purchase). If you would like to participate in this program, let me know and I will create a discount code for you that can be used to redeem your free antibody. I look forward to hearing from you. Please let me know if you have any further questions.

Thank you for contacting us with your questions. We have not tested this antibody yet in bovine or murine tissue, however the immunogen is 100% homologous to the bovine sequence so it will most likely work. The immunogen is only 78% homologous to mouse so it is less likely to work in this species. Since we have not directly tested these species, we are unable to guarantee that ab66765 will work, however we do have a testing discount program if you would be interested in testing these antibodies in bovine or mouse samples. The blocking peptide is not currently listed in our catalog, but if you are interested in ordering it I will have it added to the catalog. The pre-immune serum is not available, however we do have non-immune rabbit serum ab7487 if you would like to use that as a control- https://www.abcam.com/Rabbit-Serum-sterile-ab7487.html I hope this information is useful, but please let me know if you have further questions and I'll be happy to help.

Thank you for contacting us and please accept all our apologies for this error and delay. Indeed, we had a confusion in our notes in regards to the reconstitution of this antibody. I can confirm now, that the vial you have received has been reconstituted in the appropriate buffer and to 50ul. The vial you have received corresponds therefore to a final concentration of 1mg/ml. I hope this information is helpful to you. Please accept once again our apologies for this confusion. Please do not hesitate to contact us if you need any more advice or information.
