AU152: An Improved Gradient Method for the AAA-Direct™ Separation of Amino Acids and Carbohydrates in Complex Sample Matrices

Instrument Type: IC

In this Application Update, we combine into a single method individual improvements made to the standard AAA-Direct gradient program. These individual improvements are now in the AAA-Direct manual. This update shows that such combined changes to the AAA-Direct method improve the performance of our previously published method. This new method successfully determines amino acids in yeast extract-peptone-dextrose yeast culture medium (YPD Broth), and Dulbecco’s modified Eagle’s (with F-12), M199, L-15 (Leibovitz), and McCoy’s 5A media for mammalian cell culture.
