Why is the buffy coat important?
The high concentration of WBCs and platelets make the buffy coat a critical bio-fluid in the medical research field, enabling academic professionals to conduct experiments and study these essential cells and how they work in the body — which in turn can shape the direction of medicine and effective patient treatment.

What is the significance of the buffy coat?
The main reason to examine a buffy coat is to look for abnormal white blood cells that are circulating in the blood stream.
What does a thick buffy coat indicate?
The study shows that buffy coat thick films are useful and can detect malarial parasites in 27.8% of patients whose conventional thick films show negative parasitemia.
What does the buffy coat separate?
BUFFY COAT – a cellular fraction containing platelets and white blood cells obtained from centrifugation of anticoagulated whole blood, which separates the blood components by density.
What is the buffy coat method?
In order to optimize and facilitate the diagnostics of blood parasites, a concentration technique was developed for application in parasitology research, the buffy coat method (BCM). The method is based on blood centrifugation and the resulting separation of blood cells and parasites in different layers [45].
Why is the buffy coat important?
The buffy coat is commonly used for DNA extraction, with white blood cells providing approximately 10 times more concentrated sources of nucleated cells. They are extracted from the blood of mammals because mammalian red blood cells are anucleate and do not contain DNA.
What is buffy coat and what is its clinical importance?
Buffy coats are important for DNA isolation from blood samples. ... The generation of buffy coat from the whole blood sample helps to concentrate large volumes of blood samples so that it decreases the downstream during cell separation and handling.
What is buffy coat and its uses?
The buffy coat is used to extract DNA from the blood of mammals (since mammalian red blood cells are anucleate and do not contain DNA). This offers an option for purifying large amounts of gDNA from relatively small sample sizes.
What is the main component of the buffy coat layer?
A buffy coat is a mix of lymphocytes, monocytes, granulocytes, and platelets, isolated from plasma and RBCs by centrifugation. PBMCs, on the other hand, are individual fragmented lymphocytes and monocytes that separate from the rest of the whole blood sample through a process called density-gradient centrifugation.
What does a thick buffy coat indicate?

The method is based on blood centrifugation and the resulting separation of blood cells and parasites in different layers [45].
What is buffy coat analysis?
Quantitative buffy coat (QBC) analysis, which is based on principle of centrifugal stratification of blood components, is a well-known and a very sensitive technique which can be used for the detection of malarial parasites in peripheral blood.
What does a thick buffy coat indicate?
The study shows that buffy coat thick films are useful and can detect malarial parasites in 27.8% of patients whose conventional thick films show negative parasitemia.
What is the significance of buffy coat?
A buffy coat contains leukocytes in a concentrated suspension, originating from whole blood or bone marrow. Generating a buffy coat from whole blood samples helps to concentrate large sample volumes and reduce downstream cell separation handling.
What is buffy coat and what is its significance?
The buffy coat is commonly used for DNA extraction, with white blood cells providing approximately 10 times more concentrated sources of nucleated cells. They are extracted from the blood of mammals because mammalian red blood cells are anucleate and do not contain DNA.
What makes up buffy coat of a centrifuged whole blood sample?
A buffy coat is a mix of lymphocytes, monocytes, granulocytes, and platelets, isolated from plasma and RBCs by centrifugation. PBMCs, on the other hand, are individual fragmented lymphocytes and monocytes that separate from the rest of the whole blood sample through a process called density-gradient centrifugation.
How do you separate buffy coat of blood?
The buffy coat is removed by aspiration, resuspended in plasma and recentrifuged in tubes made from pasteur pipettes. From such narrow columns buffy coat suspensions may be recovered virtually free of red blood cells (<6 per cent).
When blood is separated the buffy coat is composed of?
A buffy coat is a mix of lymphocytes, monocytes, granulocytes, and platelets, isolated from plasma and RBCs by centrifugation. PBMCs, on the other hand, are individual fragmented lymphocytes and monocytes that separate from the rest of the whole blood sample through a process called density-gradient centrifugation.
What is the significance of the buffy coat?
The main reason to examine a buffy coat is to look for abnormal white blood cells that are circulating in the blood stream.
What is the difference between DNA extracted from whole blood and buffy coat?
The use buffy coat allows to purify large amounts of gDNA using only very small samples. Buffy coat fraction from whole blood yields approximately 5–10 times more DNA than an equivalent volume of whole blood. In this technical note, we describe the use of up to 1 ml of buffy coat per sample.
How do you do the buffy coat smear?
What is the buffy coat used for?
The buffy coat is commonly used for DNA extraction, with white blood cells providing approximately 10 times more concentrated sources of nucleated cells. They are extracted from the blood of mammals because mammalian red blood cells are anucleate and do not contain DNA.

Why is it called the buffy coat?
When researchers put the sample through a centrifuge, a machine that spins the blood, those WBCs and platelets combine to form their own layer suspended between the red blood cells (RBCs) and supernatant plasma. This thin layer is called a buffy coat because of its color (yellowish to brownish).
