The myeloperoxidase content of the normal human leucocyte has been established as
greater than 5% of the dry weight, which is contrary to the often quoted value of 1–2%. The
conditions for the preparation of a new cellular particulate in which the peroxidase activity is
localized is described; it is heavier than mitochondria, and contains at least 10–30 times
more peroxidase than the particulate fractions carrying the cytochrome oxidase activity.
Abstract
The myeloperoxidase content of the normal human leucocyte has been established as greater than 5% of the dry weight, which is contrary to the often quoted value of 1–2%. The conditions for the preparation of a new cellular particulate in which the peroxidase activity is localized is described; it is heavier than mitochondria, and contains at least 10–30 times more peroxidase than the particulate fractions carrying the cytochrome oxidase activity.
