    LOT NUMBER GR10374-2 ORDER NUMBER -- NOT SPECIFIED -- DESCRIPTION OF THE PROBLEM No signal or weak signal SAMPLE Human Cell lysate - whole cell (Breast cancer cell line) PRIMARY ANTIBODY Concentration or dilution: 1:250 <- 1:1000 Diluent buffer: PBS 1X Incubation time Over night: (16h) Incubation temperature: 4 oC. DETECTION METHOD ECL / ECLPlus / Odyssey POSITIVE AND NEGATIVE CONTROLS USED Datasheet do not mentioned any cell line for control. ANTIBODY STORAGE CONDITIONS When the antibodies come immediately aliquot and stored at -20 C, as recommended. SAMPLE PREPARATION Lysis buffer RIPA buffer Protease inhibitors: Yes. Complete mini (Roche) Phosphatase inhibitors: I don’t use. Reducing agent: B-mercaptoEthanol Boiling for ≥5 min? Yes. 5 min!

ELECTROPHORESIS/GEL CONDITIONS 5) Percentage of gel: Reduced Denaturing (12%) TRANSFER AND BLOCKING CONDITIONS Type of membrane: Amersham Hybond ECL Nitrocellulose Membrane Protein transfer verified: Yes. Blocking agent and concentration: BSA 5% Blocking time: 1h Blocking temperature: Room temperature. SECONDARY ANTIBODY Secondary antibody: Non-Abcam antibody was used: Anti-mouse (Working with other antibodies in my lab) and conjugate with fluorophores Species:Goat Reacts against: Mouse Concentration or dilution 1:10000 (that is usual in my lab). Diluent buffer PBS 1X. Incubation time 1h HOW MANY TIMES HAVE YOU TRIED THE APPLICATION? 7 HAVE YOU RUN A "NO PRIMARY" CONTROL? Yes DO YOU OBTAIN THE SAME RESULTS EVERY TIME? Yes WHAT STEPS HAVE YOU ALTERED? Sonicate samples in one experiments and change dillutions of primary antibody. ADDITIONAL NOTES Dear colleagues In the last year I acquired 8 antibodies from Abcam. Some worked perfectly without adjustments to my methods. For others, I'm still making adjustments and at this time would abstain about them. However, this antibody [v-myb+ a-myb (MYBL1)] I could never detect any bands. I'm very disappointed with the quality of this antibody and request a replacement for it. Nevertheless, I would like to exchange the product for another one of your company. The antibody that would be most helpful at this point of my thesis would be the anti-CDC42 (ab64533). I hope that this partnership and preference that I gave to your company can help me in my application request. Thank you very much.

    Thank you for your enquiry regarding ab10934 and for taking the time to provide some useful details of the experiments. I am very sorry to hear that you are having problems with this antibody. The ab10934 was only tested using Xenopus lysates; the antibody does not react with human and mouse cells so I am sorry I do not understand why the antibody was used in human lysates although its non reactivity is clearly mentioned on the datasheet. Please check the datasheet; https://www.abcam.com/v-myb-a-myb-antibody-5e11-ab10934.html Using antibodies in non tested species or applications actually voids Abcam Abpromise guarantee. Please check the Abpromise Guarantee period at following link https://www.abcam.com/index.html?pageconfig=abpromise We have another antibody ab45150; https://www.abcam.com/v-Myb-c-Myb-antibody-EP769Y-ab45150.html which is tested in human and fully guaranteed; you may consider buying this. I have also had a look at the protocol and would like to ask few more details regarding the secondary antibody. It is mentioned that the secondary antibody is Fluorophore conjugated. Could you specify which fluorophore it was conjugated with? I presume it is conjugated with either HRP for ECL detection or con conjugated with Infrared dye for Odyssey. Could you also provide the order number of purchase? I will look forward to hearing from you soon.
