牛牛天天人人综合影院 Immunohistochemistry kit
The  kit   is  based  on   the  HRP   streptavidin  Conjugate  (HRP   streptavidin
Conjugate of HRP SA). It can be used to detect specific Thy1 antigen in the
Blood,  cell or organization. The kit has high sensitivity and specificity, accurate
qualitative and quantitative analysis, and a clear background. First of all, after
the combination of primary antibody and the corresponding target antigen of
the Thy1 used before, combine the biochemical secondary antibody    with the
primary antibody with an anti specific way, finally join the HRP SA, then the
antigen   specific primary antibody   biotinylated secondary antibody HRP SA
complex is formed, and you can observe the imaging with a microscope.
Principles and main steps of the kit

to 1000ml
3.  10 mL of buffered glycerol mounting medium
4. Tween 205 mL
Immunohistochemical staining of paraffin-embedded tissue
Experimental procedure (proposed):
Paraffin embedded tissue sections of 4  m thickness
1.Drilled  piece:  Place  the  slice  on  the  sliced  rack, bake  at  60℃  constant
temperature oven for at least 1hour;
2. Dewaxing: Put the slice into a container filled with xylene dewaxing for three
times;
3.Hydration: Hydrate the  slice through the downstream  alcohol, pure ethanol
5min, ethanol of 95% concentration for 2 times(2 min per time) ethanol of 85%
concentration  for  2 min,  ethanol  of  75%  concentration  for  2  min,  flush  with
water, ddH2O 2×2min；
4.Antigen  retrieval:  Retrieve   the  antigen   according  to  the   recommended
method  of  antibody   instructions,  usually  using  high   pressure,  microwave
(temperature of 98 to 100 ° C) or enzymatic digestion repair method,
natural cooling，tap water，ddH2O washing 2 × 2min, TBS washing (2 × 2min)
(Note: some antigen Needless to repair directly to step 5 closing) ；
5. Closing: dropping reagent B, incubating in wet boxes (37 °C) for 30 min；
6.Add primary antibody: dropping reagent C, incubating in wet boxes (37 °C)
for 2 hour；
7.Washing：  TBS T washing（3×5 min）；
8.Closing：  dropping reagent B，incubating in wet boxes (37 °C) for 10min；
9.Add secondary antibody:  dropping  the biotinylated secondary  antibody(reagent D)
incubating in wet boxes (37 °C) for 30min；
10.Washing：  TBS T washing（3×5 min）；
11.Closing：  Dropping reagent Tween 20，incubating in wet boxes (37 °C) for
20min；
12．Add HRP SA：dropping reagent E which is diluted with reagent C  （1：
50~200，final concentration 5~20 nM）,incubating in wet boxes (37 °C) for
30min；
13.Washing：  TBS T washing（3×5 min）, TBS washing（2×5 min）；
14. Color: DAB solution (reagent F) color ；
15.Stained:Tap the full flush, recolor, transparent；
16.  Closing  the  slice: When  the  tissue  sample  is dry,  closing  the  slice  with
reagent buffered glycerol mounting medium；
17. Observing the imaging: Observe the imaging with microscope；
 Notes :
1.  After it is retrieved, it should be cooled with natural way, it must be rinsed
before removing the slice.  Quench may result in crystallization or antigen
closed.
2.  The buffer must ensure that the slices can be soaked , the citrate buffer
used before can not be used repeatedly.
3.  If the reagent is trace concentrate, the inner lid and wall attached to the
