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.
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.
What are the composition of nelson's reagents and their functions?
Nelson's A solution contains acetic acid, which acts as a fixative and decalcifying agent, while Nelson's B solution contains alcoholic formalin, which is a fixative. Together, these reagents are used in histology to preserve tissues for microscopic examination.
What is the most common refrigerant used in household refrigerators is?
The most common refrigerant used in household refrigerators is R-134a.
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.
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.
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 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.
What fixative used for cytological non-gynecological specimen?
CytoFix is a commonly used fixative for cytological non-gynecological specimens. It helps preserve the cellular structure and prevent degradation during processing and staining for analysis under the microscope.
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 secondary fixative?
A secondary fixative is a chemical solution used to enhance or preserve the fixation of biological tissues after an initial fixation step. It typically follows a primary fixative and is employed to improve the preservation of cellular structures, proteins, or nucleic acids for subsequent analysis, such as microscopy or molecular studies. Secondary fixatives can improve the quality of tissue samples by providing additional cross-linking or stabilization of cellular components. Common examples include alcohols, acetone, or osmium tetroxide.
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.
What is a good substitute for the fixative used on charcoal or pastel drawings?
Hair spray is a pretty good substitute.
What is farmer's fixative?
Farmer's fixative is a chemical solution used in histology and cytology to preserve biological tissues for microscopic examination. It typically consists of a mixture of formaldehyde, ethanol, and acetic acid, which helps to maintain the cellular structure and prevent decay. This fixative is particularly useful for preserving the morphology of plant and animal tissues, allowing for detailed study and analysis.

What does FIXATIVE do?
A fixative is a chemical solution used to preserve biological tissues or cells by stabilizing their structure and preventing decomposition. It works by cross-linking proteins and other cellular components, thereby maintaining the integrity of the sample for microscopic examination. Common fixatives include formaldehyde and ethanol, which help preserve the morphology and prevent enzymatic degradation. Fixatives are essential in histology and pathology for accurate diagnosis and research.
