Immunofluorescent analysis of Lin28 (green) showing cytoplasmic staining of NCCIT cells (right panel) compared to HeLa cells (left panel). The cells were fixed with formalin for 15 minutes, permeabilized with 0.1% Triton X-100 in TBS, washed, and then blocked with 3% BSA-PBS for 30 minutes at room temperature. Cells were probed with a DyLight 488-conjugated Lin28 monoclonal antibody (Product # MA1-016-D488) in 3% BSA-PBS at a dilution of 1:100 and incubated for 1 hour at 37C in the dark. F-Actin (both panels, red) was stained with DyLight 554 Phalloidin (Product # 21834) and nuclei (both panels, blue) were stained with DAPI. Images were taken at 60X magnification.
