SDS-PAGE zymography of serum samples. Three serum samples taken from controls and three samples from subjects with type 1 diabetes were subjected to gel electrophoresis to detect possible gelatinolytic activities, in the absence (Panel A) and presence of 10 m EDTA (Panel B). The migration position of the 72 kDa (proMMP-2) and 92 kDa (proMMP-9) and dimeric proMMP-9 (225 kDa) standards are shown at the right side of panel A.
