Detailed explanation-1: -neutrophil, type of white blood cell (leukocyte) that is characterized histologically by its ability to be stained by neutral dyes and functionally by its role in mediating immune responses against infectious microorganisms.

Detailed explanation-2: -The name neutrophil derives from staining characteristics on hematoxylin and eosin (H&E) histological or cytological preparations. Whereas basophilic white blood cells stain dark blue and eosinophilic white blood cells stain bright red, neutrophils stain a neutral pink.

Detailed explanation-3: -Used in an alkaline-buffered solution on fixed smears of bone marrow or peripheral blood, the oxazine dye CI basic blue 141 preferentially stained neutrophil granules a bright crimson red. In neutrophils, these granules were numerous, whereas in bands, only a few granules were seen.

Detailed explanation-4: -Introduction. Neutrophils, also known as polymorphonuclear (PMN) leukocytes, are the most abundant cell type in human blood.

Detailed explanation-5: -Because of the segmented appearance of the nucleus, neutrophils are sometimes referred to as “segs.” The nucleus of less mature neutrophils is not segmented, but has a band or rod-like shape.
