Quantitation of Albumin and Creatinine in Urine by MALDI-TOF Mass Spectrometry
October 1st 2016This MS-based method represents a simple, fast, and attractive alternative to current immunoassay-based methods for the quantitation of albumin and creatinine in urine. This protocol enables the direct detection and measurement of the intact analytes from the same sample preparation, requiring only a 10-fold dilution of a urine sample into a MALDI-TOF matrix solution.
