RNA Extraction from Cartilage Tissue Using Cryogenic Grinding

The aim of the study, in this application note, was to determine if there is a connection between the seriousness of arthritic diseases, especially of the knee joint and certain genes. To this end the expression profile of various genes in the tissue of healthy and diseased probands was compared. Total RNA was isolated from cartilage tissue and the activity of certain genes was analyzed via PCR or micro array analysis.
