Popis: Peptide mapping of underivatized tryptic digests of bovine and chick intestinal calcium-binding proteins has been accomplished by high performance liquid chromatography (HPLC). High precision analysis of nanomolar quantities of peptides were achieved in less than 1 h (recycle time). Peak resolution and definition are superior compared to conventional techniques and recoveries of both small (4-residue) hydrophilic and large (30-residue) hydrophobic peptides are excellent. The total amino acid composition of the bovine intestinal calcium-binding protein has been accounted for on the basis of two tryptic maps of 20 microgram of protein each.
