[RASMB] peptides and dialysis

[Holger Strauss]

Dear all,

does anyone of you know of a good method/product to get small peptides
(2-4 kDa) to osmotic equilibrium with either aqueous buffer or TFA/aqueous
buffer mixtures?  We find the dialysis membranes and ultracentrifugation
devices we have to be way to "leaky" to our peptides.

Thanks a lot for your help, Holger
