From: A role for the collagen I/III and MMP-1/-13 genes in primary inguinal hernia?
Northern Blot analysis of type I and type III collagen mRNA from cultured fibroblasts. The ratio of 28S to 18S rRNA (ribosomal RNA) was approximately 2 : 1 by ethidium bromide staining of denaturing agarose gel electrophoresis, indicating that no gross degradation of extracted RNA occurred. 1. primary inguinal hernia; 2 control
