fer without affecting the binding of the proteins to PVDF. The results are consistently clean, easy-to-read blots. The physical strength of Immun-Blot PVDF membrane means that it will not crack or tear during common handling, and will hold up under repeated stripping and reprobing applications.

Sequi-Blot PVDF Membrane
For protein sequencing applications, Sequi-Blot PVDF membrane is the best choice due to its extremely high protein binding capacity of 170200 g/cm². This is the original Bio-Rad PVDF membrane, designed to withstand the conditions of N-terminal sequencing while providing the binding capacity to sequence even low-abundance samples. The table shows the increased protein recovery possible with Sequi-Blot PVDF membrane. Recovery of blotted proteins is typically in the range of 80100% of the initial sample load, resulting in higher initial coupling yields.

The binding efficiency of Sequi-Blot PVDF membrane is illustrated in Figure 3. This experiment showed that Sequi-Blot PVDF membrane is able to retain proteins that transfer through a competitors product.
