buffy coat

Buffy Coat can be used to increase detection.

The layer next to buffy coat contains granulocytes and red blood cells.

In such cases the medical technologist may obtain a buffy coat, from which a blood smear is made.

Rapid diagnosis of neonatal sepsis by Buffy coat examination.

More than 100 consecutive buffy coats from normal individuals were processed by this method and cultured.

Motile organisms may be visible in the buffy coat when a blood sample is spun down.

Above this is a whitish layer of white blood cells (the "phlegm", now called the buffy coat).

The wash bowl filling continues until the buffy coat reaches the shoulder of the wash bowl.

In centrifuged blood, T. cruzi trypomastigotes are found just above the buffy coat.

Buffy coat may sometimes be green if there are large amounts of neutrophils in the sample, due to the heme-containing enzyme myeloperoxidase that they produce.

The layer between the red cells and the plasma is referred to as the buffy coat and is sometimes removed to make platelets for transfusion.

For the initial dilution control studies, CD4 cells were purified by immunomagnetic separation from donor buffy coats.

Quantitative buffy coat (QBC) is a laboratory test to detect infection with malaria or other blood parasites.

Some autotransfusion devices have automatic features including a buffy coat sensor, which is calibrated to detect a full bowl and advance the process to the wash phase automatically.

The buffy coat is usually whitish in color, but is sometimes green if the blood sample contains large amounts of neutrophils (which are high in green myeloperoxidase).

Blood sampling has followed a strict quality protocol, collecting serum, plasma, buffy coat, immortalized cells for cell line production, specialized tubes for trace metal/elements-analysis, RNA-tubes and urine.

The buffy coat is the fraction of an anticoagulated blood sample that contains most of the white blood cells and platelets following density gradient centrifugation of the blood.

The buffy coat is used, for example, to extract DNA from the blood of mammals (since mammalian red blood cells are anucleate and do not contain DNA).

Donor lymphocyte (or leukocyte) infusion (DLI) or buffy coat fusion is a form of adoptive immunotherapy used after hematopoietic stem cell transplantation.

Isolation of peripheral blood monocytes Mononuclear cells were isolated from buffy coat preparations of healthy blood donors by density gradient centrifugation with Histopaque 1077 (Sigma).

Elutriation procedure for BMPCs Anticoagulant-treated, platelet-depleted buffy coat was obtained in sterile packages from the North London Blood Transfusion Service.

Making up less than 1% of the total volume of the blood sample, the buffy coat (so-called because it is usually buff in hue), contains most of the white blood cells and platelets.

For blood samples, these include centrifugation followed by examination of the buffy coat; mini anion-exchange/centrifugation; and the quantitative buffy coat (QBC) technique.

Since the "buffy coat" layer sits directly atop the RBC layer, HES, a sedimenting agent, is employed to improve yield while minimizing RBC collection.
