Figure Lengend Snippet: Colocalization of intracellular LAMP-1 with GrzB and the 15 kDa (RF10) or 9 kDa (pc) form of Gnly in NK-92 cells. Following fixation and permeabilization, cells were stained with FITC-conjugated anti-LAMP-1 mab. After washing, cells were additionally stained with PE-conjugated anti-LAMP-1 mab (as a positive control for colocalization), PE-conjugated anti-GrzB mab, or with anti-Gnly mab RF10 or a polyclonal anti-Gnly pab (pc) and appropriate Alexa Fluor 555-conjugated secondary antibodies. A total of 10,000 cells were acquired with an ImageStream Mark II imaging flow cytometer. Only focused, single cells were considered for further analyses. ( A ) Histograms display the geometric mean value of the BDS score of respective stainings and the percentage of cells displaying a BDS score >2. ( B ) Representative images of stained cells. Scale bars represent 7 µm.
Article Snippet: For granulysin staining, we also used an unconjugated anti-Gnly mab (clone RF10, MBL International, Woburn, MA, USA) with Alexa-Fluor 555-conjugated goat anti-mouse polyclonal antibody (pab) (Thermo Fisher Scientific) and unconjugated anti-Gnly pab from goat (RD Systems, Minneapolis, MN, USA) with Alexa-Fluor 555-conjugated donkey anti-goat pab, respectively.
