1- H&E
Aim : demonstration of nucleus the mammalis
Section : T.S in liver of mammalia
T.S in kidney of mammalia
T.S in ileum of the mammalia
T.S in adrenal gland of the mammaila
Color : cytoplasm (red) ….. nucleus ( deep blue )
2-Hg- bromophenol blue
Aim : identification of total protein
Section : T.S in liver of Rabbit
T.S in ileum of the Rabbit
T.S in adrenal gland of the Rabbit
T.S in kidney of Rabbit
Color :
cytoplasm (deep blue )
The nucleus isn't stained
The degree of color depend on the protein
Concentration in
cytoplasme and cell membrane
3-Alcian blue (Cu- phathelo cyanine )
Aim : identification of acid mucopolysaccarides (mucoids)
Section : T.S in ileum of the Rabbit
Color :
cytoplasm ( pale green color )……. Nucleus : not stained
4-Silver nitrate
Aim : Reveal
golgi complex
Golgi complex found in cytoplasm and its depend on the
physiological condition for the animal
Color : dark brown to black deposits
Section : T.S in liver of Rabbit
T.S in kidney of Rabbit
T.S in adrenal gland of the Rabbit
T.S in the Vas deferens
of the Rabbit
5-PAS (periodic acid Schiff reaction
Aim : Identification of carbohydrates
Section : T.S in the liver of mammals
Colour: Cytoplasm à purple colour
Nucleus
à colorless
Mechanism :-
1)
Oxidation : HIO4 is a weak oxidizing agent used to
oxidize the carbohydrate to aldehyde
2)
Schiff reagent preparation
6-Stain : Fulgen reactionAim : identification of DNA
Section : T.S in the testes of the mammals
Color : cytoplasm
à colorless nucleus
à purple color
7- Immunohistochemical method
1- in this method we aim to detect a single protein
2-this is done usinga spcific (antibody) “polyclonal - monoclonal”
3- this is (antigen-antibody) complex can be detected by two different methods
A) The direct method : at which tje flarochrome ia attachedto
the 1ry antibody can be only detected using flurocent microscope
(UV) light source
B) The indirect method : at which tje flarochrome ia attachedto the 2ry antibody
- can be only detected using flurocent microscope (UV) light source
- at which a streptavidin interactes with HRP [Horse Raddish Peroxidose]
in the presence of DAB [ Di Amino Benzidin]
and a block celover is formed at the sited expression
- TNFR2 ... Tumer Necrosis Factor Receptor 2 protein (Localized in the ONL, Outer Nuclear Layer and INL , Inner Nuclear layer) of the retina of carp larva (bony fish).
- HSP70, Heat shock protein 70 , which is localized at the OPL (outer plexiform layer) of the retina of carp larva (bony fish).
بنشكر دكتور صلاح على تعبة معانا جدا 😊😊😊
