- Western blot analysis was performed on whole cell extracts (30 µg lysate) of Hep G2 (Lane 1), HEK-293 (Lane 2) and K-562 (Lane 3). The blot was probed with DHFR Polyclonal Antibody (Product # PA5-30992, 1:1000 dilution) and detected by chemiluminescence using Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A27036, 0.25 µg/ml, 1:4000 dilution). A band at 20kDa corresponding to DHFR was observed across the cell lines tested.

- Western Blot using DHFR Polyclonal Antibody (Product # PA5-30992). Whole cell extract (30 µg) was separated by 12% SDS-PAGE, and the membrane was blotted with DHFR Polyclonal Antibody (Product # PA5-30992) diluted at 1:1,000. The HRP-conjugated anti-rabbit IgG antibody was used to detect the primary antibody, and the signal was developed with Trident ECL plus-Enhanced.

- Knockdown of DHFR was achieved by transfecting HEK-293 cells with DHFR specific siRNAs (Silencer® select Product # s4081, s4082). Western blot analysis (Fig. a) was performed using whole cell extracts from the DHFR knockdown cells (lane 3), non-specific scrambled siRNA transfected cells (lane 2) and untransfected cells (lane 1). The blots were probed with DHFR Polyclonal Antibody (Product # PA5-30992, 1:1000 dilution) and Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A27036, 0.25 µg/ml, 1:4000 dilution). Densitometric analysis of this western blot is shown in histogram (Fig. b). Decrease in signal upon siRNA mediated knock down confirms that antibody is specific to DHFR.
