Collagen IV Immunostain, Technical Component Only
Use
The test serves as a marker of the basal lamina of capillaries and basement membranes in all organs. Collagen IV stains the structures within capillaries, glomerular and tubular basement membranes, and mesangial cells within the kidney's glomeruli, providing valuable insights into the structural integrity of these tissues.
