The aim of the current study was to neutrophil isolation 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 (HBSS) 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 light microscopy. 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 fast technic for isolation of the neutrophils from venous blood samples of dogs.
