What is the white blood cell that stains a red or rosy color?
Eosinophil is a white blood cell that stains a red or rosy color when using certain stains, such as eosin, in laboratory tests. Eosinophils play a role in the immune response against parasites and in allergic reactions.
What so endospore stain have in common with the acid-fast stain?
One thing that endospore stains have in common with the acid fast stain is that heat primary stain penetration. Another thing that endospore stains have in common with acid fast stains are counterstain.
What are the common stains that is used after DNA electrophoresis?
Common stains used after DNA electrophoresis include ethidium bromide, SYBR Safe, and GelRed. These stains intercalate with DNA and allow visualization under UV light. They are used to detect and analyze DNA fragments separated on the gel.
What solution of a dye or group of dyes that imparts a color to microorganisms?
A common solution used to impart color to microorganisms is the Gram stain, which uses a combination of crystal violet and safranin dyes. Crystal violet stains all bacteria purple initially, then iodine is used to fix the dye in the cell wall. Alcohol treatment differentially removes the dye from certain bacteria, allowing the counterstain safranin to color those bacteria pink or red.
What does basophilic cytoplasm mean?
Basophilic cytoplasm refers to a cell's cytoplasm that stains blue-purple when exposed to certain dyes or stains in a laboratory setting. This staining pattern is typically seen in cells that have high amounts of ribosomal RNA and protein production, such as in actively secreting cells or cells with high metabolic activity.
What is easier to detect when using forensic light?
Blood stains are typically easier to detect using forensic light, as they contain hemoglobin that fluoresces when exposed to certain wavelengths of light. This fluorescence can make blood stains stand out more visibly against different surfaces.
What does Sudan IV reagent detect?
Sudan IV reagent is a dye used to detect the presence of lipids and fats in a sample. It is commonly used in laboratory tests to detect the presence of lipids in food samples or in forensic analysis. Sudan IV stains lipids red, allowing for easy visual detection.
What substance is stained by Sudan dye?
Sudan dye stains lipids or fats. It is commonly used in laboratory settings to help visualize and detect the presence of lipids in cells or tissues.
What is the white blood cell that stains a red or rosy color?
Eosinophil is a white blood cell that stains a red or rosy color when using certain stains, such as eosin, in laboratory tests. Eosinophils play a role in the immune response against parasites and in allergic reactions.
What might be the source if an unexpected bacteria appears on a finished smear even if a clean slide was used?
The unexpected bacteria on a finished smear could be due to contamination during the staining process, improper handling of the samples, or a cross-contamination issue in the laboratory environment. It is important to review the laboratory procedures and quality control measures to identify and address the source of contamination.
What are the functionally analogous pair of stains?
Crystal violet and safranin are functionally analogous pair of stains in the Gram staining technique. Crystal violet stains gram-positive bacteria purple/blue, while safranin counterstains gram-negative bacteria pink/red.
What stains a penny?
Time and bacteria can sometimes leave marks on coins.
How do I prevent pink stains on bath?
Its a bacteria called Serratia marcescens
How do you detect semen stains?
Semen stains can be detected using a forensic light source that causes the stains to fluoresce under certain wavelengths of light. Additionally, chemical tests such as the Acid Phosphatase Test or the Microscopic Examination Test can also be used to detect the presence of semen stains on a surface. DNA analysis can provide confirmation of the presence of semen and identify the individual it came from.
What can detect semen stains?
As far as I know... REAL blacklights will detect any trace of a mammal.... hair, urine, vomit, feces, and... sperm!! just make sure the room is as dark as you can get it and shine that light around until something glows!
What is the use of Koplin jar in the laboratory?
to hold slides for staining or in between stains to rinse excess away with water
Which brand of stain remove remove stains?
Genesis 950 - by far the best stain remover available. In addition to removing stains, it also kills bacteria which prevents odors - GREAT for pet stains and carpet cleaning!
