| 主权项 | 1. An immunoassay method for measuring a protein in a urine specimen, comprising pretreating the urine specimen by mixing the urine specimen with cysteine and urea, or cysteine and sodium n-dodecylbenzenesulfonate (SDBS), and then measuring the protein in the urine specimen by performing immunoassay, thereby improving assay sensitivity for the protein. | ||
