URINE PRETREATMENT AGENT FOR URINARY PROTEIN QUANTITATION, URINE PRETREATMENT METHOD, AND URINARY PROTEIN QUANTITATION METHOD

摘要

The present invention is intended to develop a urine pretreatment agent, a urine pretreatment method, and a urinary protein quantitation method which reduce or cancel the influences of urine pH variations, cancel the influences of precipitates of urinary inorganic salts, and solubilize membrane proteins. The present invention provides: a urine pretreatment agent for urinary protein quantitation, comprising a buffer, a chelating agent, and a surfactant; a urine pretreatment method comprising a step of mixing 10 to 1000 parts by mass of the urine pretreatment agent of the present invention with 100 parts by mass of urine; and a urinary protein quantitation method comprising steps of: mixing 10 to 1000 parts by mass of the urine pretreatment agent of the present invention with 100 parts by mass of urine; and then measuring the protein concentration.
