Western blot analysis of Wnt2b on different lysates with Rabbit anti-Wnt2b antibody (ET7107-20) at 1/1,000 dilution. Lane 1: K-562 cell lysate (20 µg/Lane) Lane 2: Neuro-2a cell lysate (20 µg/Lane) Lane 3: C6 cell lysate (20 µg/Lane) Lane 4: Mouse brain tissue lysate (40 µg/Lane) Lane 5: Mouse testis tissue lysate (40 µg/Lane) Lane 6: Rat testis tissue lysate (40 µg/Lane) Predicted band size: 44 kDa Observed band size: 44 kDa Exposure time: 10 seconds; ECL: K1801; 4-20% SDS-PAGE gel. Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody (ET7107-20) at 1/1,000 dilution was used in 5% NFDM/TBST at 4℃ overnight. Goat Anti-Rabbit IgG - HRP Secondary Antibody (HA1001) at 1/50,000 dilution was used for 1 hour at room temperature.
