Figure: Staining of paraffin section of synovial tissue from a patient with Rheumatoid Arthritis. Arrows indicate vessels (20x) staining positive for BAFF using Buffy-2.
Method: Tissues are in paraffin sections. Sections are de-waxed and rehydrated, then cooked. Sections are stained in wet boxes, rehydrated and finally prepared as coverslip slides using Eukitt solution.
