Thanks for the brilliant advice and this seems silly now but I don't know
how I would go about lyophilizing a peptide, can anyone help?

I would concentrate the peptide in a "Speed-vac": you freeze it and
then put it in a centrifuge under vacuum, the solvent will evaporate,
but the PBS salts will be concentrated along with the peptide.
Otherwise, you could lyophilize the peptide and re-dissolve it with
H2O, to whatever volume you like.
