IHC/ICC procedure for frozen sections, paraffin sections, cell smears and immunoblots. 1. Deparafinize and hydrate tissue sections through xylene or other clearing agents and graded alcohols. (For frozen sections or cell smears; use unfixed, acetone fixed or appropriate fixative for the antigen in question; for cell smears it may be necessary to permealize the cell by detergent, please refer to antibody protocol) 2. Wash 2-3 with distilled or deionized water. 3. Wash slide with Tris/saline buffer, followed by blocking with normal blocking serum, rinse with buffer. 4. Block with reagent S (streptavidin) for 5-10 minute, rinse with buffer. 5. Now block with reagent B (Biotin) for 5-10 minutes, wash thoroughly with buffer.
