<prompt> In renal biopsy specimen Jones methenamine silver stain is used for:Assess cellularity and architectureStain carbohydrate moieties in the membranes of the glomerular tuftEnhance basement membrane structureIdentify collagen deposition  <response>: A renal biopsy quickly identifies the type of glomerular injury and suggests a course of treatment. The stains used in light microscopy specimen are: 1. Hematoxylin and eosin HE to assess cellularity and architecture 2. Periodic acid-Schiff PAS to stain carbohydrate moieties in the membranes of the glomerular tuft and tubules 3. Jones-methenamine silver to enhance basement membrane structure 4. Congo red for amyloid deposits 5. Massons trichrome to identify collagen deposition and assess the degree of glomerulosclerosis and interstitial fibrosis. Ref: Harrison-18, P-2339.
