ab25475 staining CD4 (red) in mouse spleen tissue sections by Immunohistochemistry (IHC-Fr - frozen sections). Tissue was fixed with paraformaldehyde and blocked with 5% BSA for 1 hour at 25°C. Samples were incubated with primary antibody (1/100 in PBS) for 12 hours at 4°C. A Cy3®-conjugated Donkey anti-rabbit IgG polyclonal (1/500) was used as the secondary antibody.
Flow Cytometry analysis of BALB/c mouse splenocytes labeling CD4 with ab25475 at 1 μg/106 cells dilution (purple). A Mouse Anti-Rat IgG2b-PE was used as the secondary antibody. Grey - Isotype Control, Rat IgG2b-UNLB followed by Mouse Anti-Rat IgG2b-PE.
