Avidin/Biotin Blocking Kit Set
Some tissue sections contain endogenous biotin, biotin binding proteins, lectins or non-specific binding substances. Tissues may also bind avidin, biotin, peroxidase biotin, peroxidase streptavidin in avidin biotin based Immunohistochemistry. These tissues will give high background in the absence of biotinylated secondary antibodies. It may be necessary to block the tissue with avidin, followed by biotin. These reagents are added before the primary antibody.

IHC/ICC procedure for frozen sections, paraffin sections, cell smears.
- 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)
- Wash 2-3 with distilled or deionized water.
- Wash slide with Tris/saline buffer, followed by blocking with normal blocking serum, rinse with buffer.
- Block with reagent A (Avidin) for 5-10 minute, rinse with buffer.
- Now block with reagent B (Biotin) for 5-10 minutes, wash thoroughly with buffer. Note: If antigen retriever is required it can be applied after this stage.
- Wash slide with PBS or Tris saline (with 0.02-0.05% nonionic detergent, Triton X100, Tween 20 or NP-40) or washing buffer (Immuno Automation buffer IBSC cat # AR-6561) 3-5X.
- Follow instructions for IHC/ICC.
