    The majority of human adenocarcinomas including colorectal, pancreatic, gastric, ovarian, endometrial, mammary, and non-small cell lung cancer display some cell populations that are positive for TAG72. About 60% of carcinoma patients express TAG72 in their sera. TAG72 is reportedly useful in distinguishing pulmonary adenocarcinomas from pleural mesotheliomas.

    Answer

    Thank you for your phone call this week and for your patience while I looked into your questions. I have heard back from the production lab of ab691, and the IgG concentrations vary among the lots that we have in stock: 60ug/mL for lot # 958786 33.3ug/mL for lots # 958785, 958787, 975535, and 975468   The protein carrier in the concentrated antibody diluent is BSA and the preservative is sodium azide.  I hope this information is helpful, but please let me know if you have any further questions.

    Asked on Apr 21 2006

    Answer

    Thank you for your reply. Both of these antibodies are tissue culture supernatant meaning that it is not possible to determine antibody concentration, since tissue culture supernatant contains proteins besides the antibody of interest. Supernatant is the fluid resulting from centrifugation of hybridomas in tissue culture that are secreting specific monoclonal antibodies. Supernatants therefore typically contain culture medium, 5-10% fetal calf serum, and other proteins. Antibody concentration is only relevant for purified antibodies. I hope this information helps, please do not hesitate to contact us if you need any more advice or information.

    Asked on Apr 11 2006

    Answer

    Thank you for your enquiry. There's no concentration information available for this antibody as it is provided in an unpurified form (tissue culture supernatant) and we cannot determine the concentration for unpurified products. To use the antibody in IHC-P, it is recommended to dilute the antibody 1/50-1/100. Please contact us again if you have any additional questions.

    I have purchased two different lots of this antibody. Lots #48242 and 74306. This lots are behaving differently in my ELISA protocol. Do you have any information about these two lots that would account for this occurence?

    Answer

    Thank you for your enquiry. We are very sorry to hear that you are having some difficulty with this product. We would like to confirm that the two batches you are having are different, however we have not received any technical enquiry which would indicate that there is some batch-related problem. We would like to emphasize that this product has not been characterised for ELISA application only for IHC staining. We hope this information will be useful.
