TurnaroundTarget turnaround: 5 business days from receipt, one analysis batch per week. Measured turnaround is published once validation is complete.
Dissolving powdersPowders that simply dissolve in water or buffer are standard service — included in the test price, no preparation charge. PREP-1 (+$30) applies only when a solid needs weighing, extraction and filtration; acid hydrolysis is separate (PREP-H, +$80).
Volume and repeat workFree amino acids drop to $125 per sample at 25+ samples a month and $99 on a standing monthly order. A whole bioreactor run is one package (RUN-1).
Academic rateUniversities and non-profits: mention it when you book and ask about the education rate. Minimum order $150.

What we don't do. Accredited (GLP, GMP or ISO/IEC 17025) testing for regulatory submission or batch release, protein content by nitrogen, and tryptophan or cysteine after acid hydrolysis.

Priced after a free feasibility call

The extended amino acid panel (AA-2), cysteine and cystine (AA-3), and custom HPLC method development depend on your samples. A free 30-minute call tells you whether the method fits and what it costs; development then has a fixed project price.
