Figure 2. Specificity of mouse antisera raised against recombinant SMSB3 and SMSB4.
The purified SMS proteins and BSA (used as a non-related control) were electrophoresed on SDS-PAGE and stained with Coomassie blue R-250 (A) and then immunoblotted with the anti-sera raised against SMSB3 (B) and SMSB4 (C), confirming the specificity of the antibodies and lack of cross-reaction with BSA.
