Representative 2D gel images obtained using urine samples collected from a hospitalized, 28 day old, preterm newborn infant (29 weeks gestation) via (A) Gauze insert diapers (B) Non-gel diapers and (C) Low-gel diapers. Urine collections occurred on 3 consecutive days (over a 3–7 hour period) and a different diaper type was used each day. At the end of the collection period, urine was expressed from non-stool containing diapers and pooled for 2D-PAGE.
