    • Host species

      Rabbit
    • Specificity

      Ab64857 is not guaranteed for WB with endogenous protein since Ab64857 has been batch tested in WB using recombinant full length FGF21 protein only and not all batches detect endogenous FGF21 protein in WB. For endogenous FGR21, we recommend RabMAb ab171941 (Anti-FGF21 antibody [EPR8314(2)])

      Question

      I tested the new lot GR85839 and the results are identical compared to the previous one (GR71375-1). So this is good news for me.

      In additional, one of my colleague tested another lot of the same antibody (GR85321-1). This lot works even better. Could you tell me how many vials of the lot GR85321-1 you still have in stock please?

      Question

      Good afternoon,

      Here is the questionnaire filled out.

      Yes I would prefer to receive the lot number GR71375-1 in a big quantity (maybe 20 vials, 20*50uL, for approximately 83 plates). A discount would be very appreciated.

      I’m waiting your answer.

      Asked on Nov 26 2012

      Answer

      Thank you for taking time to complete our questionnaire and for contacting us. I am sorry to hear this antibody is not providing satisfactory results.

      The details provided will enable us to investigate this case and will provide us with vital information for monitoring product quality. I appreciate the time you have spent in the laboratory and understand your concerns. It is regrettable the results have not been successful.

      Having reviewed the protocol details, I believe this product should have given satisfactory results. It appears that you may have received a faulty vial.

      I apologize for the inconvenience and am pleased to offer you a free of charge replacement, credit note, or refund in compensation.

      With regards to the lot GR71375-1 which gave good results, we only have 3 units left of it so we will not be able to supply you with enough of this antibody to do 83 plates. However, we have 30 units of another lot in stock which isn't GR15961-1. What I suggest is that I send you a free of charge replacement of this different lot so that you can test it in ELISA. If this antibody works, you can then purchase more vials of it for the rest of your experiments.

      Please note that our antibodies are supplied in 100ul vials and that for any order of 5 or more vials, we can offer you a discount.

      Thank you for your cooperation. I look forward to hearing from you with details of how you would like to proceed.

      Question

      Good afternoon,

      I tested the following antibody anti-FGF21 with the lot GR15961 I received and compared with the previous lot I had (GR71375).

      I obtained a big difference of signal between both.

      Could you tell me if it’s still possible to order the LOT NUMBER GR71375?

      Asked on Nov 22 2012

      Answer

      Thank you for contacting us.

      I am sorry to hear you are experiencing difficulties with one of our products. We take product complaints very seriously, and investigate every product that we feel may not be performing correctly.

      I am attaching our questionnaire so that we can gather further information regarding the samples tested and the protocol used. I have attached 3 different questionnaires so please only fill out the one which is relevant to your experiment. This information will allow us to investigate this case internally and initiate additional testing where necessary.

      If the product was purchased in the last six months and is being used according to our Abpromise, we would be happy to refund or replace the antibody with an antibody from the lot GR71375 which we still have in stock in the USA.

      I look forward to receiving your reply.
