Immunofluorescence analysis of Krueppel-like factor 2 (KLF2) was performed using HUVEC cells treated with 10 ng/mL of human TNF-alpha recombinant protein (Product # PHC3013) for 4 hours. The cells were labeled with anti-KLF2 monoclonal antibody (OTI3A10) (Product # MA5-26827) (Panel a & c: Green). The composite ( b & d) represents the merged image with DAPI (blue) and F-actin (red) staining. Cells treated with TNF-alpha displayed downregulation of KLF2 compared with the untreated cells. The images were captured at 60X magnification.
