ALGAL LYOPHILIZED CELLS (U-13C+; U-15N) consist of lyophilized algal biomass enriched with uniformly labeled 13C and 15N, providing a complex mixture of naturally occurring amino acids and amino acid-containing metabolites derived from the organism. The labeling pattern indicates carbon and nitrogen atoms throughout the cellular constituents, while the lyophilized, non-protected material retains native amino and carboxyl functionalities present in the endogenous amino acid pool without introducing discrete amino-acid protecting groups or esterification. This isotopically labeled cell material is used for isotopic tracing, quantitative mass spectrometry workflows, and preparation of labeled biological samples or downstream amino acid/peptide fractions for structure-function studies and analytical method development.
