Immunofluorescence

Immunofluorescence analysis of paraformaldehyde fixed U937 cells on coverslips, permeabilized with 0.15% Triton and stained with the chimeric rabbit IgG version of rhPM-1 (Tocilizumab) at 10 ug/mL for 1h followed by Alexa Fluor 488 secondary antibody (1 ug/mL), showing membrane staining. The nuclear stain is DAPI (blue). Panels show from left-right, top-bottom, DAPI, merged channels and an isotype control. The isotype control was stained with an anti-Fluorescein antibody followed by Alexa Fluor 488 secondary antibody.
