A study of detection and comparison of immunofluorescence on formalin-fixed paraffin-embedded tissue with fresh frozen renal biopsy specimen
Direct immunofluorescence on the fresh frozen tissue is established way of demonstrating of immunoglobulins and complement deposition in renal biopsies. IF studies can be done on paraffin-fixed tissue (IF-P) and give comparable results to those obtained on frozen tissue for most pathogenic immunoglo...
