Description

Amino Acids Quantified: L-Alanine, L-Arginine, L-Asparagine*, L-Aspartic Acid, L-Cysteine*, L-Cystine, L-Ethanolamine, L-Glutamic Acid, L-Glutamine, L-Glycine, L-Histidine, Hydroxy-L-Proline, L-Isoleucine, L-Leucine, L-Lysine, L-Methionine, L-Ornithine, L-Phenylalanine, L-Proline, L-Citrulline, L-Serine, L-Taurine, L-Threonine, L-Tryptophan, L-Tyrosine, L-Valine, L-Alanyl-Glutamine, Gamma-Aminobutyric Acid***

*L-Cysteine is not included in the standard panel for Free Amino Acid Analysis as it often is oxidized into L-Cystine. Thus, Cysteine analysis is often to check for presence rather than quantity since its rate of oxidation is unpredictable. It can be quantified but needs freshly made specialty standards. If you need quantification of Cysteine in your sample(s), please add quantity 1 of test code #5045 Cysteine Standards to your order.

**L-Asparagine eludes as part of a triad with L-Glutamic Acid and L-Glutamine. If the Glutamic Acid concentration is less than 5 micromoles per liter, the Asparagine is baseline resolved. To calculate the most accurate results for the baseline resolved Asparagine, a specialty standard containing Asparagine (test code #5042) is run with a sample to obtain more accurate quantification. Without the specialty standard with low Glutamic Acid, results may be up to 20% off for reported Asparagine.

***L-Alanyl-Glutamine is not included in the standard panel for Free Amino Acid Analysis but can be quantified by request using freshly made specialty standards (test code #5046).

Each standard (pair) will be $255 per order for all customers.
