Specificity
Napsin A reactivity was determined immunohistochemically on formalin-fixed paraffin-embedded cell blocks from 50 pleural effusion (5 mesotheliomas, 10 mesothelial proliferations, 12 pulmonary, and 23 nonpulmonary metastases). Napsin A was positive in 10/12 pulmonary adenocarcinomas. The specificity of this antibody for primary lung adenocarcinoma is 47 out of 58 (81%), primary lesions were positive. -

Flow Cytometry - Anti-NAPSIN A antibody [KCG1.1] (ab73021)Overlay histogram showing A549 cells stained with ab73021 (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 (ab73021, 1/100 dilution) 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. This antibody gave a positive signal in A549 cells fixed with 4% paraformaldehyde (10 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.
