Stripe blots of crude HeLa cell extract stained with MCS-4C4. Note two strong clean bands at 74 kDa and 64 kDa, corresponding to Lamin A and C, in the lane labeled 6. Lane 5 was stained with our antibody to Enolase 1, which we will market shortly. Lanes 3 and 4 were reacted with 5J11, a monoclonal antibody to all six actin isotypes. Molecular weights of each protein are as indicated.
