- Basic science
What is the background of the project?
Immunohistochemistry (IHC) is used to understand the distribution and localization of proteins in tissues which detects specific antigens using an appropriate antibody labeling strategy. Immunohistochemistry (IHC) is the gold standard methodology for in-situ protein expression analysis in tissue samples. For this purpose, samples are collected, fixed and antigenicity of target epitopes, and then sectioned. A variety of antibody staining schemes can produce informative IHC images.The Turkish Society of Histology and Embryology has been founded in 1990 with collaboration of both veterinary and medical professionals.Turkey has established IHC units and embryologists who work on two major fields: identification of genetic abnormalities in embryological tissue samples during or after pregnancy, and research related to natural developmental processes of the fetus. Our unit works with 6 histology/embryology specialists and has access to IHC labs and molecular imaging techniques.
What is the aim of the project?
Investigating immunohistochemical levels of various antibody in different tissue samples.
What techniques and methods are used?
We used a caspase-3 (rabbit polyclonal to caspase-3, ab4051, Abcam, UK) immunohistochemistry kit as a primary antibody to mark apoptotic cells. Sections 3-4 μm taken from the paraffin blocks using a microtome (Leica RM2125RT, Germany) were placed onto positively charged slides. The sections obtained were then kept for 10 min in 3% H2O2 solution. The sections were next washed in phosphate buffer solution (PBS) and incubated with citrate buffer solution for 5 min, and were then kept for 15 min in secondary blocking solution. They were then incubated with primary antibody (Caspase-3, Rabbit polyclonal to Caspase-3, 1/100, ab4051, Abcam, UK) and secondary antibody (EXPOSE Rabbit specific HRP/DAB (HRP: horseradish peroxidase, DAB: 3, 3-Diaminobenzidine) detection IHC Kit, ab80437, Abcam, UK) for 60 min. Finally, sections stained with Harris hematoxylin and diaminobenzidine chromogen solution were covered with entellan (Superior Mansfield, Germany).
What is the role of the student?
- The student will mainly observe
What are the tasks expected to be accomplished by the student?
The student will observe or be involved under supervision in the following tasks: 1- Marking of apopitotic cells with Caspase 3 2- Using the Leica RM2125RT microtome to prepare the paraffin slides used for imaging 3- Preparing the microslides using a 3-step fixation procedure; 10mins at 3% H2O2 then wash with phosphate buffer then incubate with citrate buffer for 5 mins 4- Observing the use of the EXPOSE Rabbit specific HRP/DAB (HRP: horseradish peroxidase, DAB: 3, 3-Diaminobenzidine) detection IHC Kit 5- Occasionally examining the embryonic tissue slides prepared in the IHC lab
Will there be any theoretical teaching provided (preliminary readings, lectures, courses, seminars etc)
