[PDF] antigen retrieval frozen sections

Antigen Retrieval for Frozen Sections
  • Rinse sections three times for 5 min each in PBS.
  • Cover sections with 1% SDS solution and incubate for 5 minutes at RT.
  • Rinse 3 X 5 min each in PBS. (It is important to wash sections well).
  • Proceed with staining as normal.

  • Do frozen sections need antigen retrieval?

    For frozen sections, antigen retrieval is not required as the fixation time with aldehydes is very short (10–30 minutes) and doesn't allow the formation of cross-links. Figure 1 illustrates the benefit of optimizing antigen retrieval to improve staining. Figure 1.

  • How long is antigen retrieval in frozen section?

    Antigen retrieval is usually not required for immunostaining of fresh frozen sections (they are usually sectioned and fixed with ice-cold acetone for 5-10 minutes). Antigen retrieval methods depend on your specific antigen and the primary antibody you will use to immunolabel it.16 avr. 2019

  • How do you heat antigen retrieval frozen sections?

    Immerse the tissue blocks in a retrieval solution (10 mM sodium citrate buffer, pH 6.0) at 4 ºC overnight. Place the tissue blocks in a small, heat-resistant basket and immerse in boiling retrieval solution (200–500 ml) with gentle stirring using a hot plate for 3–5 min.
  • Note: Since the effect of antigen retrieval reagents depends on their temperature (90-100 °C) and incubation time (up to 30 minutes), optimal conditions should be determined by the individual investigator.
