Immunofluorescence localization of calmodulin in human polymorphonuclear leukocytes.
Human polymorphonuclear leukocytes (PMNs) were purified (approximately equal to 99%) from peripheral blood of normal, adult volunteers. The indirect immunofluorescence technique was used to investigate the presence and the localization of calmodulin in human PMNs. The cellular distribution of calmodulin has been evaluated using an affinity chromatography-purified sheep IgG anti-calmodulin and fluorescein-conjugated rabbit anti-sheep IgG. The anti-calmodulin immunofluorescence pattern suggests that calmodulin is evenly distributed throughout the cytoplasm of human PMNs.
