A rapid and sensitive method for quantitation of rat macrophages using neuraminidase-treated sheep or guinea pig erythrocytes

Study of spontaneous rosette formation and changes of sialic acid content in the surface glycoproteins of macrophages induced by hamster transplantable melanomas

The influence of two kinds of transplantable melanomas on the content of sialic acids in the surface glycoproteins of hamster peritoneal macrophages was studied, and the ability of these cells to form spontaneous rosettes. It has been found that the intensification of rosette formation by macrophages with SRBC depends on the melanoma line. No correlation has, however, been found between changes in the sialic acids content and the ability of macrophages to form rosettes under the influence of melanomas differing in malignancy.

The binding of SRBC by human peripheral blood monocytes

In a population of E-rosette forming human peripheral blood cells, about 20% of the rosettes were formed by monocytes. About 60% of the peripheral blood monocytes bound SRBC in a standard E-rosette test.
