    This data was developed using ab205581, the same antibody clone in a different buffer formulation. Flow cytometric analysis of 4% paraformaldehyde-fixed A549 (human lung carcinoma cell line) cell line labeling IGFBP4 with ab205581 at 1/500 dilution (red) compared with a Rabbit IgG, monoclonal [EPR25A] - Isotype Control (ab172730) (black) and an unlabeled control (cells without incubation with primary antibody and secondary antibody) (blue). Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) at 1/2000 dilution was used as the secondary antibody.

    Immunoprecipitation - Anti-IGFBP4 antibody [EPR19762] - BSA and Azide free (ab251435)
    This data was developed using ab205581, the same antibody clone in a different buffer formulation.IGFBP4 was immunoprecipitated from 0.35 mg of A549 (human lung carcinoma cell line) whole cell lysate with ab205581 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab205581 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/10000 dilution. Lane 1: A549 whole cell lysate 10 µg (Input). Lane 2: ab205581 IP in A549 whole cell lysate. Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab205581 in A549 whole cell lysate. Blocking and dilution buffer and concentration: 5% NFDM/TBST. Exposure time: 1 second. Note: Human IGFBP4 has 2 isoforms detected at 28 kDa and 18 kDa.
