What is the  likelihood that Glycine is contaminated by other amino
acids (eg glutamate or aspartate). I've talked to the technical people
at Sigma and Gibco (where I obtained the samples). Both assured me
that there is no contamination, yet my assay indicates otherwise. any
comments or suggestions. Please e-mail or post.
