The current study aimed to isolate neutrophils from venous blood samples of healthy dogs. Venous blood samples were obtained from Venae cephalica of clinically healthy dogs (n:5) into heparinized tubes. The blood samples (2 mL) and Percoll dilutions (45%, 54%, 63%, and 72%) prepared with Hanks Balanced Salt Solution were layered into sterile tubes. After centrifuge, the polymorphonuclear leukocytes (PMN) were aspirated between 63% and 72% interfaces of the Percoll dilutions into tubes. The samples of PMN observed under a light microscope. Viability was detected microscopically after stained with trypan blue dye. Diff-Quick staining was used to detect neutrophil purity of the isolated PMN. In the present study, the neutrophils ratio was calculated as 92% of the isolated polymorphonuclear cells. The neutrophil viability was calculated as 98% of PMNs isolated from the venous blood samples of healthy dogs. In the present study, the Percoll gradient centrifugation (72%, 63%, 54%, and 45%) is a fast technic for isolation of the neutrophils from venous blood samples of dogs.
