Simultaneous determination of 33 amino acids and dipeptides in spent cell culture media by gas chromatography-flame ionization detection following liquid and solid phase extraction.
A rapid, sensitive and reproducible gas chromatographic method with flame ionization detection is described for the simultaneous identification and quantification of 33 amino acids and dipeptides in spent cell culture media in under seven minutes. The method involves the use of the EZ:faast(Phenomenex) amino acid sample testing kit. Instrumental and assay precision, percent recovery, linear range, limit of detection and peak identity in highly complex cell culture media containing either soy hydrolysate or fetal bovine serum were validated using gas chromatography-flame ionization detector (GC-FID).
