I have searched online and haven’t been able to find a definitive list, though what I have found I will include below. My methodology is as follows:

0.5 ml of an algal extract solution (alkaline extract of powdered material) was added to an Amicon Ultra-0.5 Centrifugal Filter Devices with a 3000 Nominal Molecular Weight Limit (NMWL). This was then centrifuged at 14,000 x g for 5 minutes, producing both filtered (3000 NMWL portion).

What I have found so far (in terms of what passes through the filter membrane and what does not):

What passes through membrane -

· 16-32 Bp DNA

· 10-20K molecular weight proteins

What doesn’t pass through membrane:

· mainly above 25 Bp DNA

· Mainly above 15K molecular weight proteins

Any help, particularly any sources of information, would be greatly appreciated.
