What is the most commonly used fixative for routine histology?

The most commonly used fixative for routine histology is formalin, specifically buffered formalin. This fixative helps preserve tissues by stabilizing proteins and preventing degradation, allowing for better preservation of cellular structures for microscopic examination.


What is the Ratio of fixative volume to tissue?

The typical ratio for fixative volume to tissue is 10:1, meaning 10 times the volume of fixative compared to the volume of the tissue. This ensures proper fixation and preservation of the tissue structure for further analysis. Adjustments to this ratio may be needed depending on the tissue size and fixative used.


How does Carnoy's solution act?

Carnoy's solution is a fixative creating covalent chemical bonds between proteins in tissue. Most commonly used fixative in histology is formaldehyde. It prevents decay.


What is fixation in specimens?

Fixation in specimens is a process used in biology and medicine to preserve the structure of cells and tissues. It involves treating the specimen with a fixative solution that immobilizes cell and tissue components, preventing decay and maintaining their original structure for further analysis under a microscope. Fixation is a crucial step in preparing samples for techniques such as histology, immunohistochemistry, and electron microscopy.


What does protoslo do to a specimen?

Protoslo is a preservative used to prevent decay and decomposition of specimens. It replaces water inside the specimen with a preservative solution, helping to maintain the structure and integrity of the specimen over time.

Can baking soda be used as fixative for dyeing?

No, baking soda cannot be used as a fixative for dyeing. A fixative is a substance used to set or bind dyes to the fabric, and baking soda does not have this property. Common fixatives for dyeing include vinegar, salt, and commercial fixatives.


What is the most common fixative used in haematology?

Human-made structures cytological preparations?

Cytological preparations are samples of cells suspended in a liquid. They are used in diagnostic testing to examine cell morphology and detect abnormalities. Human-made structures, such as cell culture plates and slides, are often used to create these preparations in a controlled laboratory setting.


Is picric acid a dye or fixative?

Picric acid is primarily used as a fixative in histology to preserve tissue specimens for microscopy. It is not commonly used as a dye in the same way that other chemicals like hematoxylin and eosin are used to stain tissues for visualization.


What is Carnoy's fixative?

Fixatives are classified as coagulative fixatives and cross-linking fixatives. Carnoy's fixative is a coagulative fixative. Coagulative fixatives change the shape or structure of protein molecules without binding to them, while cross-linking fixatives bind chemically to protein molecules at one or more points. In cross-linking fixatives molecules are linked together to form an insoluble latticework by forming chemical bridges between protein chains. Carnoy's fixative is a coagulative fixative.
