4 materials:

PVDF, 0.45 um: Standard PVDF with 0.45 um pore size for most proteins (> 20 kDA)

PVDF, 0.2 um: 0.2 um pore size for smaller proteins (< 20 kDA) or Sequencing

PVDF, Fluor: Optimized for fluorescence, extremely low background compatible with most imagers, 0.45 um pore size)

Nitrocellulose: Standard NC with 0.45 um pore size for most proteins (> 20 kDA)

Should I use PVDF or Nitrocellulose?
GenHunter prefers PVDF for the reasons shown below. However, we know that some customers prefer Nitrocellulose, so we offer both types.

Advantages of PVDF:

Better protein retention (Pluskal, BioTechniques. 1986, 4:272)
Much more durable allowing easier handling due to higher mechanical strength
Higher binding capacity (100-200ug/cm^2) vs. NC (80-100ug/cm^2)
Lower concentrations detected: Requires 5X less antigen, 20X less serum, 10X less secondary antibody (Dalessio, J. Clin. Micro. 1992, 30:1005)
Superior chemical resistance makes it ideal for staining and re-probing
