A weighed sample is hydrolysed, typically in hydrochloric acid at around 110 degrees for a day, under vacuum or inert gas. The hydrolysate is analysed by ion-exchange chromatography with post-column derivatisation or by pre-column derivatisation and reversed phase. Each amino acid is quantified, and the sum, corrected for the residues not recovered, is the protein content.
The method is slower than spectrophotometry and more accurate.
The sequence predicts, for example, six cysteines, one methionine and defined counts of each other residue. Measured ratios close to prediction confirm the composition; a deviation points to a truncation, a wrong sequence or a contaminant. For a recombinant protein this is a second identity check independent of mass.
The extension adds its own residues to the expected counts, so the analogue and native IGF-1 give different compositions.
Protein content by amino acid analysis, often used to assign the content of a reference lot against which routine lots are measured by absorbance or chromatography. A 1 mg vial contains the stated mass of lyophilised material; this method says how much of it is protein.
