Identification of protein expression in HEK-293T cells using western blot analysis. The clear bands were observed for L1-GFP (lane 1, ∼52 kDa), L2-GFP (lane 2, ~50 kDa) and GFP (lane 4, ~27 kDa) proteins, respectively. Any clear band was not detected in un-transfected cells as a negative control (lane 3). MW is molecular weight marker (prestained protein ladder, 10–170 kDa, Fermentas).
