WebCystinuria, a genetic disorder of cystine transport, is characterized by excessive excretion of cystine in the urine and recurrent cystine stones in the kidneys and, to a lesser extent, in the bladder. Males generally are more severely affected than females. The disorder may lead to chronic kidney disease in many patients. Webcystine and 2.5 pM aspartic acid was used to check the procedure and to establish the color factor for X-sulfocysteine on a Beck- man-Spinco model 120C amino acid analyzer. The color values obtained for both amino acids were identical with those obtained when the derivitization procedure was applied to the calibration ...
