    • CD1d was immunoprecipitated from 0.35 mg of Jurkat (human T cell leukemia cell line from peripheral blood) whole lysate with ab229903 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab229903 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used as secondary antibody at 1/5000 dilution.

      Lane 1: Jurkat whole cell lysate 10 µg (Input). 

      Lane 2: ab229903 IP in Jurkat whole cell lysate. 

      Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab229903 in Jurkat whole cell lysate.

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

      Exposure time: 30 seconds.
