An improved method for isolation of granulocytes from peripheral blood
Journal of Immunological Methods
|January 1, 1978
Summary
This study presents a new method for isolating granulocytes from human blood, achieving a higher yield (70.9%) than existing techniques. The isolated cells maintain their function, making them suitable for purity-essential research.
Area of Science:
- Hematology
- Immunology
- Cell Biology
Background:
- Granulocyte isolation is crucial for various immunological and clinical studies.
- Existing methods often yield insufficient cell numbers or compromise cell function.
Purpose of the Study:
- To develop and validate a novel method for efficient granulocyte isolation from human peripheral blood.
- To assess the yield, purity, and functional integrity of the isolated granulocytes.
Main Methods:
- A new isolation technique was applied to human peripheral blood.
- Granulocyte yield was quantified and compared to existing methods.
- Cell composition, functional assays (phagocytosis, candidacidal activity, NBT reduction), and purity were evaluated.
Main Results:
- The novel method achieved a significantly higher granulocyte yield of 70.9%.
- Isolated cells were primarily neutrophils, with a preserved eosinophil-to-neutrophil ratio.
- Functionally, the cells were comparable to buffy coat granulocytes.
Conclusions:
- This method provides a superior yield of functional granulocytes from human peripheral blood.
- The high purity achievable makes the isolated cells ideal for specific research applications.
- The technique offers a valuable advancement for hematological and immunological research.
