Fig. 3From: Syringe-push membrane absorption as a simple rapid method of urine preparation for clinical proteomicsStorage duration of urinary proteins absorbed on the nitrocellulose membrane after SPMA procedure. After urine protein absorption, the membrane was air dried and kept at room temperature until elution at 1-day, 1-week and 1-month. Immediate elution served as control condition. 2-DE was performed to assess protein degradation and/or modification after long storage. No change of urinary proteome was observed up to 1-monthBack to article page
