Enzyme-histochemical detection of glycosidases in synovial fibroblast cells. Enzyme-histochemical staining of rheumatoid arthritis (RA) and osteoarthritis (OA) synovial fibroblast monolayers for β-D-glucuronidase (GusB) and β-D-N-acetyl-glucosaminidase (NAG) using fluorogenic substrates. Nuclear areas show no fluorescent staining.
