Facts (generated by robot; please edit if you find it inaccurate)

• At acidic pH, a dramatic increase in accumulated [35S]cystine is observed in cystinosin-GYDQL-expressing cells but not in mock-transfected cells.
• Since cystine is very unstable in physiological samples, it is essential to handle the blood sample in a very precise manner.
• White cells are used because cystine is not elevated in red cells or plasma of cystinosis patients.
• Because cystine is not reabsorbed by the kidneys, it becomes a part of the kidneys’ product: urine.
• Cystine is an amino acid, one of the building blocks of proteins.
