  • General notes

    The Life Science industry has been in the grips of a reproducibility crisis for a number of years. Abcam is leading the way in addressing the problem with our range of recombinant monoclonal antibodies and knockout edited cell lines for gold-standard validation.

    One factor contributing to the crisis is the use of antibodies that are not suitable. This can lead to misleading results and the use of incorrect data informing project assumptions and direction. To help address this challenge, we have introduced an application and species grid on our primary antibody datasheets to make it easy to simplify identification of the right antibody for your needs.

      IHC image of ab2215 staining in human lung formalin fixed paraffin embedded tissue section, performed on a Leica Bond system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab2215, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

      For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

      Overlay histogram showing Jurkat cells stained with ab2215 (red line). The cells were fixed with 4% paraformaldehyde (10 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab2215, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in Jurkat cells fixed with 80% methanol (5 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.

    Question


    I have a question for 2 of your products an anti-CD9 (ab2215) and an anti-CD63 (ab8219).
    There is an information in their product Datsheet that I don't really understand.
    Ex : For WB use a concentration of xx µg/ml. Use under non reducing condition
    "Non reducing condition" is about my sample? These antibodies need dissulfide bound to recognize epitopes?

    Asked on Mar 27 2013

    Answer

    ab2215 should be used at a concentration of 2-4 ug/ml in blocking buffer when incubating your membrane whereas ab8216 should be used at a concentration of 2 ug/ml.

    The gel should be run in non-reducing conditions as these antibodies do not recognise their antigens well when the western blot sample contains reducing agent. We therefore advise against adding beta-mercaptoethanol or DTT in the loading buffer.

    Question

    I have recently purchased two primary antibodies, anti-CD9 antibody (ab2215) and anti-CD63 (ab8219) which I have been using with human proteins. It has been working fine, but I was wondering if you've encountered binding with Bovine proteins.

    Answer

    Thank you for contacting us.

    The antibodies have not been tested for reactivity with bovine samples, and we have not received reports of bovine reactivity from our customers.

    Please do not hesitate to contact us if you need any more advice or information.

    Question

    BATCH NUMBER 163262 ORDER NUMBER -- NOT SPECIFIED -- DESCRIPTION OF THE PROBLEM lots of bands and not at the right predicted molecular weight for cd9 SAMPLE as a positive control used full lysed DCs (NP40 lysis buffer, protease inhibitors: the samples however are the different fractions of a cell separation using a continuous iodixanol density gradient solution: trying to find a DC-SIGN/CD9 positive endosomal compartment. (used human DCs) PRIMARY ANTIBODY cd9 (Abcam) have tried it at different dilutions: 1/100, 1/500, 1/1000 dilutant: PBS/0.1% tween incubation time: 1 hour wash 3X for 10 min with PBS/tween DETECTION METHOD ECL POSITIVE AND NEGATIVE CONTROLS USED positive: full DCs ANTIBODY STORAGE CONDITIONS -20 C SAMPLE PREPARATION 15ul of sample (either fractions or full cell lysis) and 15ul of 2X loading buffer (no DTT) (and samples not heated) AMOUNT OF PROTEIN LOADED not exactly known, but in the full cell lysis there should be a lot of it ELECTROPHORESIS/GEL CONDITIONS non-reducing gel, 4-12% TRANSFER AND BLOCKING CONDITIONS transfer onto nitrocellulose, 100mA in transfer buffer blocking agent: milk powder SECONDARY ANTIBODY anti-mouse HRP (Sigma) in PBS/0.1% Tween (2ul/5ml) 1 hour wash 3X for 10 min with PBS/Tween HOW MANY TIMES HAVE YOU TRIED THE APPLICATION? 6 HAVE YOU RUN A "NO PRIMARY" CONTROL? Yes DO YOU OBTAIN THE SAME RESULTS EVERY TIME? Yes WHAT STEPS HAVE YOU ALTERED? concentration of anitbody and of loaded protein (have loaded as much as possible), incubation times (have left it for less and longer than an hour) ADDITIONAL NOTES I have seen that you have another CD 9 antibody which is a rabbit anti human Ab, and I would like to perhaps try that one instead. I am doing a 3-month MSc project and thus have very limited time, which I cannot afford anymore to waste on trying to get an antibody to work. Thanks in advance.

    Asked on Jun 28 2006

    Answer

    I'm very sorry to hear you are experiencing a problem with ab2215. I appreciate the urgency in resolving this problem due to the short time you gave in the laboratory, and I believe that with the following protocol tips you will have improved results with ab2215. Often non specific bands are due to the following problems: 1) protein degradation. we recommend the following inihibitors to be present in the lysis buffer: Aprotinin 2 µg/ml , Leupeptin 5-10 µg/ml, Antipain 2-10 µg/ml, Pepstatin A 1 µg/ml, Na-Fluoride 5-10 mM, phosphatase Orthovanadate 1 mM , PMSF 1 mM. If one of those has degraded in your samples this may explain the problem. Furthermore as you are performing a complicated fraction protocol this provides further opportunities for the proteases to act if they are not totally inhibited (please make sure all steps are carried out at 4C too). 2) the antibody is not binding to the membrane adequately. This can be due to too little or too much blocking (what percentage do you use and how long is your incubation for?). This can make a hughe difference in the binding ability of the antibody. I would recommend to try 5%BSA for 1 hour and incubating the membrane in TBST only overnight (TBST is better than PBST). The problem can further be due to too much primary antibody, so it is best to dilute the antibody more and incubate longer, to provide a slow but targeted binding to the protein of interrest (you may also find you can dilute the secondary more too). I hope the above recommendations will help you. Please do not hesitate to contact me again if I can be of further help,
