Cystine capacity
WebA new method of measuring urinary cystine and estimating potential for stone formation, called cystine capacity, may prove to be a useful tool in monitoring the disease. The discoveries of the mutations that cause cystinuria have led to a new classification system based on genotype that is more accurate than the prior phenotypic one. WebOct 6, 2024 · The internal standard was prepared as follows: 100 mg of cystine-d6 was dissolved into 100 mL of 1 N HCl (aq.) to produce a 1.0 mg/mL solution of cystine-d6. A 10 × dilution of the commercially available 0.1 mg/mL solution of cotinine-d3 was prepared in 0.1 N HCl (aq.) to create a 0.01 mg/mL solution of cotinine-d3.
