Appendix: application protocol 1 Deparaffinizing and H&E stain
For research use only
Deparaffinization and hydration

Appendix: application protocol 2 Immunohistochemistry
For research use only
IHC(immunohistochemistry)
Immunohistochemistry is an exquisitely sensitive method for locating an antigen within a cell or tissue through a high-resolution image (a single cell among thousands or millions). The method is based on the use of a primary antibody binding specifically to its cognate antigen. The bound antibody is then visualized by colorimetric or fluorescent detection methods. Antigen retrieval method During the preparation of tissues for staining, antigens are heavily modified by the fixatives frequently on free amino acid groups. Because they can be hidden by other molecules, antigen retrieval procedure is required to counter these changes. There are several methods for antigen retrieval. The selection is made according to the experimental purposes. If the experiment is the conditioning process with first trial of that antibody, various methods need to be tried. 1. Proteolytic enzyme pre-treatment method Cleave the bonds formed from the fixation process. Enzymes routinely used include trypsin, pronase or trypsin, pepsin.The concentration and reaction time must be controlled since the excess enzyme treatment can damage the target antigens.
- pronase: 0.05%(W/V) in PBS or - trypsin : 0.05%(V/V) in PBS - pepsin : 0.05%(V/V) in 2N HCl Incubate in one of the above solutions at RT or 37 for 18 min Dip in cold DW
IHC procedure The protocol needs to be optimized for antibody you may want to test and/or you might need to follow instructions from suppliers.

Dry a slide at 58 overnight Deparaffinize in xylene Hydrate the slide in gradient ethanol Retrieve antigen (see left section) Dip in 3% H2O2 10-15 min and washing buffer 3 X 5 min Block with normal serum
1. Direct method
Biotin-tagged Primary Ab for 1~2 hr at RT or 37 incubator or for overnight at 4(don't wash, just change the blocking solution for primary antibody) and washing buffer 2 X 5 min
2. Indirect method
-1. Biotin-tagged primary Ab for 1~2 hr at RT or 37 incubator or for overnight at 4(don't wash, just change the blocking solution for primary antibody) and washing buffer 2 X 5 min -2. Biotin-tagged secondary Ab for 10-15min at RT and washing buffer 2 X 5 min ABC reagent (streptavidin-HRP) for 10~15min and washing buffer for 2~3 X 5 min Fresh chromogen (DAB or AEC) for 1~3 min and Wash with tap water Counter stain (the nucleus) with Hematoxylin or methyl green -1. When Hematoxylin is used : dehydrate in gradient ethanol (70% to 100%) and clear with xylene, mount with insoluble mounting medium (eg. balsam) -2. When methyl green is used : just dry and mount with soluble mounting medium (eg. glycerin or gelatin) -3. When AEC is used for chromogen : just dry and mount with soluble mounting medium
2. Heat-induced antigen retrieval method Antigens fixed in formalin are hidden by fixative and calcium ions. Chelating or precipitating these calcium ions by specific solutions like citrate buffer, EDTA and EGTA with heating can cleave these bonds.
Place the slides into a rack Immerse the slides in citrate buffer* Move the entire container into microwave oven Microwave the slides at maximum watt for 4 X 5 min ( after each cycle, replenish any lost liquid from the slide container by addition of DW) Remove the container and allow it to cool to RT Wash with appropriate washing buffer
*citrate buffer : 0.01M citric acid, pH 6.0
IHC Conditioning
Negative controls without a primary antibody, without a secondary antibody, or without detecting reagents. Why does my negative control show strong signal? Possible cause of signal Primary Ab only is omitted. The signal is due to non-specific cross-reactivity of detection reagents. Trouble shooting The secondary Ab is binding non-specifically to the tissue. Add 0.1% tissue-specific serum to the secondary Ab. Dilute the secondary Ab. Change species of secondary Ab. The secondary antibody only is omitted. The detecting reagents are binding non-specifically to the tissue. Block tissue with detection reagent. Detection reagent only is omitted. Intrinsic tissue enzyme activity is interfering with the reaction. Treat tissue with reaction solution.
Positive controls A positive antibody with the test tissue, or the test antibody with a positive tissue. Using an antibody known to react with the test tissue, or using the test antibody with cells known to contain the antigen. Fixatives may have reduced access of the antibody to the antigen. Perform microwave target retrieval procedure or protease digestion. Why does my positive control have no signal? Possible cause of no signal Ab may be too dilute. In most cases, this is because the antibody is not optimized or the tissue is not adequately treated. Trouble shooting Titrate Ab to determine the optimum dilution that gives the best signal-to-noise ratio. Ensure secondary Ab is directed against the species of primary Ab, e.g. anti-mouse secondary Ab for mouse primary Ab This can be confirmed by performing by dot blot test.
Secondary Ab does not recognize the primary Ab.
The enzyme/substrate system is defective or incompatible.
