Has anyone used Nrf2-antibody from Santa Cruz (sc-722) and found several very strong bands on Western blot?

The product data sheet gives the main band at 57 kDa, but I have 4 main bands, one at about 100 kDa, two that could be 57kDa (I ran a mini-gel so it's hard to differentiate), and one below 50kDa....
