  • ab66332 at 1/1000 dilution staining Calnexin in human Hela cells by immunocytochemistry/ Immunofluorescence. An Alexa Fluor® conjugated Goat polyclonal to mouse IgG1 was used as secondary antibody. Green colour in image show positive staining with ab66332.

  • Overlay histogram showing HeLa cells stained with ab66332 (red line). The cells were fixed with 80% methanol (5 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 (ab66332, 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 IgG2b [PLPV219] (ab91366, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.
