Sepharose CL-4B gel filtration of crude saliva. An aliquot (20 ml) of soluble human crude saliva extracted in 6 M GuHCl containing 10 mM EDTA, 5 mM NEM, 1 mM PMSF and 0.1% CHAPS pH 6.5 was chromatographed and eluted with 4 M GuHCl containing 10 mM EDTA, 5 mM NEM and 0.05% CHAPS pH 6.5 at flow rate of 48 ml/h at room temperature. Fractions were analysed for carbohydrate with PAS at 555 nm () and for protein A280 (■). Materials eluted in the void volume (Vo) and included volume (Vi) were pooled separately, dialysed against three changes of distilled water for overnight at 4°C and freeze-dried.
