cryosection fixation protocol
What is a cryosectioned tissue sample?
To examine alterations in pathobiology, cryosectioned tissue samples are generated to study cellular alterations by microscopy. If tissues are not processed correctly, artifacts will result. Within this unit, the user will be instructed on the appropriate methods for generating sections from cryopreserved tissue samples.
How do you cryoprotect tissue?
Cryoprotect the tissue by directly perfusing a sucrose solution or by first dissecting the tissue and allowing it to sink overnight in a 30% sucrose/ 70% fixative solution. Embed tissue in OCT cryostat sectioning medium and store at -80° C until ready for sectioning. Tissue can be safely stored for 6-12 months.
What is a standard sample section size for cryosection?
Uniform tissue sections of 5-10 microns allow for maintenance of tissue structure and access of immunoreactive epitope within the sample section. Samples sectioned greater than 15 microns are prone to shatter during Cryosectioning (see Table 2 ). Table 2.. Common Problems when Cryosectioning and Proposed Solutions
How is a cryosection prepared?
The preparation of cryosections does not involve the dehydration steps typical of other sectioning methods, and, furthermore, sectioning, labeling, and observation of specimens can usually be carried out in one day. In general, the sample is frozen quickly in either isopentane or liquid nitrogen.
Immunohistochemistry Protocol For Fixing and Sectioning Frozen Tissues
IHC Cryosection Protocol for Fixing and Sectioning of Frozen Tissues This technique utilizes formaldehyde-based fixation before the tissue is frozen and sectioned using a cryostat. 1. To preserve tissue morphology and retain the antigenicity of the target molecules, fix the tissue by vascular perfusion with 500 - 700 mL of Formaldehyde Fixative Solution. 2. Perfuse the animal with 400 mL of Sucrose Solution. Note: When it is not possible to fix by perfusion, dissected tissue may be fixed by immersion in a 10% formalin solution for 4 to 8 hours at room temperat
Immunohistochemistry Protocol For Cryopreservation of Tissues Prior to Fixation
This method utilizes frozen tissues that are fixed after snap-freezing and sectioning with a cryostat. 1. Immediately snap freeze fresh tissue in isopentane mixed with dry ice, and keep at -70 °C. Do not allow frozen tissue to thaw before cutting. 2. Embed the tissue completely in OCT compound prior to cryostat sectioning. 3. Cut frozen sections at
Immunohistochemistry Protocol For Immunofluorescence Cryosection Staining
Immunohistochemistry (IHC) Protocol for Frozen Tissue Sections 1. When staining cryostat sections stored in a freezer, thaw the slides at room temperature for 10-20 minutes. 2. Rehydrate the slides in wash buffer for 10 minutes. Drain the excess wash buffer. Note: Excessive fixation may result in the masking of an epitope and strong non-specific background signal that can obscure specific labeling. If necessary, an antigen retrieval protocolcan be performed at this time. However, many antigen retrieval techniques are too harsh for cryostat-cut tissue sec
