  • General notes

    ab280904 is the carrier-free version of ab280900. This format is designed for use in antibody labeling, including fluorochromes, metal isotopes, oligonucleotides, enzymes.

    Our carrier-free formats are supplied in a buffer free of BSA, sodium azide and glycerol for higher conjugation efficiency.

    Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with

    ab280904 is compatible with the Maxpar® Antibody Labeling Kit from Fluidigm.

    This product is a recombinant monoclonal antibody, which offers several advantages including:

    • - High batch-to-batch consistency and reproducibility
    • - Improved sensitivity and specificity
    • - Long-term security of supply
    • - Animal-free production
    For more information see here.

    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.

    Predicted band size: 97 kDa
    Observed band size: 97,113 kDa why is the actual band size different from the predicted?



    This data was developed using ab280900, the same antibody clone in a different buffer formulation.

    Blocking and diluting buffer and concentration: Intercept® (TBS) Blocking Buffer diluted with an equal volume of 0.1% TBS.

    Lanes 1 - 3: Merged signal (red and green). Green - ab280900 observed at 97, 113 kDa. Red - loading control ab181602 (Rabbit monoclonal [EPR16891] to GAPDH) observed at 36 kDa.

    Lanes 1-2: ab280900 Anti-Stat2 antibody was shown to react with STAT2 in HeLa cells in Western blot. Loss of signal was observed when STAT2 knockout sample was used. Wild-type and STAT2 knockout samples were subjected to SDS-PAGE.

    ab280900 and Anti-GAPDH antibody [EPR16891] - Loading Control (ab181602) were incubated at 4°C overnight at 1 in 1000 dilution and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 680CW) preadsorbed (ab216777) and Goat anti-Mouse IgG H&L (IRDye® 800RD) preadsorbed (ab216772) secondary antibodies at 1 in 10000 dilution for 1 hour at room temperature before imaging.

    Stat2 was immunoprecipitated from 0.35 mg Ramos (Human Burkitt's lymphoma B lymphocyte), whole cell lysate 10 µg with ab280900 at 1/30 dilution (2 µg in 0.35 mg lysates). Western blot was performed on the immunoprecipitate using ab280900 at 1/1000 dilution. Mouse IgG for IP (HRP) (ab131368) was used at 1/5000 dilution.

    Lane 1: Ramos whole cell lysate 10 µg

    Lane 2: ab280900 IP in Ramos whole cell lysate

    Lane 3: Mouse monoclonal IgG2a (ab18413) instead of ab280900 in Ramos whole cell lysate

    Blocking and dilution buffer and concentration: 5% NFDM/TBST.

    Exposure time: 3 minutes.
