Analytes
One panel, explained amino acid by amino acid. Each page covers the chemistry in plain terms, free vs total, how the method measures it, and which panel reports it.
Amino acids in the panels
Plain-terms reference for each amino acid the panels report, including the one the free panel excludes: cysteine.
Alanine
Alanine is measured in the AA-1 free amino acid panel by AQC HPLC-UV. Free vs total explained, plus why AABA the standard is not alanine.
Explore → AnalyteArginine
Arginine is measured in the AA-1 free amino acid panel by AQC HPLC-UV. What free vs total means for cell culture media and supplements.
Explore → AnalyteAsparagine
Asparagine is measured in the AA-1 free panel by AQC HPLC-UV. Why acid hydrolysis reports asparagine together with aspartic acid.
Explore → AnalyteAspartic acid
Aspartic acid is measured in the AA-1 free panel by AQC HPLC-UV. Free vs total explained, including asparagine conversion on hydrolysis.
Explore → AnalyteCysteine and cystine
Cysteine oxidises to cystine and is excluded from the AA-1 free panel. Learn why it needs a separate AA-3 workup and what each panel reports.
Explore → AnalyteGlutamic acid
Free and total glutamic acid, explained in plain terms, with MSG-equivalent conversions using verified molar masses and the panel that reports each.
Explore → AnalyteGlutamine
Glutamine is measured free in AA-1 but converts to glutamate in total analysis. Plain guide to panels, spent media use, and hydrolysis limits.
