A depletion strategy for improved detection of human proteins from urine

J Biomol Tech. 2009 Apr;20(2):101-8.


With rapidly growing interest in the urine proteome, methods for reducing sample complexity are becoming increasingly important. Depletion strategies for removal of high-abundance proteins from human urine have not been reported. A commercial kit designed for depletion of abundant proteins from plasma was evaluated for removing top proteins from urine of patients with proteinuria. The number of low-abundance proteins identified in urine after depletion increased nearly 2.5-fold.

Keywords: affinity chromatography; protein depletion; proteinuria; proteomics; urine.
