    Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.

    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: 56 kDa
    Observed band size: 56 kDa



    This data was developed using ab274373, the same antibody clone in a different buffer formulation.

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

    Lysates loaded onto lanes 1 and 2 were made freshly and used in WB immediately to minimize protein degradation. Bands beneath the target band in lanes 5 and 7-8 may be caused by degradation.

    Negative control: K-562 and MOLT-4 (PMID: 11303025).

    The blot of lanes 5-8 was developed using a higher sensitivity ECL substrate.

    Exposure time: 3 minutes.

Confocal image showing strong cytoplasmic and weak nuclear staining in THP-1 cells is observed.

    Tubulin is detected with Anti-alpha Tubulin mouse monoclonal antibody - Microtubule Marker (Alexa Fluor® 594) (ab195889) at 1/200 dilution (Red). The Nuclear counterstain was DAPI (Blue).

    IRF5 was immunoprecipitated from 0.35 mg THP-1 (human monocytic leukemia monocyte) whole cell lysate with ab274373 at 1/30 dilution (2ug in 0.35mg lysates). Western blot was performed on the immunoprecipitate using ab274373 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP)(ab131366) was used at 1/5000 dilution.

    Lane 1: THP-1 whole cell lysate 10 ug.

    Lane 2: ab274373 IP in THP-1 whole cell lysate.

    Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab274373 in THP-1 whole cell lysate

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

    Exposure time: 15 seconds.

    Lysate was made freshly and used in IP test immediately to minimize protein degradation. Incubation time was 2h.
