  • GCLC (ab55435) at 1ug/lane + A-431 cell lysate at 25ug/lane.
  • ab55435 at 10 ug/ml staining GCLC in human Hella cells by Immunocytochemistry/ Immunofluorescence.

  • Overlay histogram showing Jurkat cells stained with ab55435 (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 (ab55435, 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.
