Anti-kappa/lambda immunobead for detection of human B lymphocytes

Polymer microbeads in immunology

Synthetic polymer microbeads have been studied extensively and the required properties, including monodispersity and size range 0.05-10 microns can best be achieved by radiation polymerization based on methacrylate derivatives. Fluorochrome-conjugated beads can be used for cell surface markers and simultaneously to study phagocytosis. The paper reviews some of these applications. Cell separation techniques are also described. Future possibilities for immunological and cell biology studies are discussed.

The mixed antiglobulin rosetting reaction (MARR) and the direct antiglobulin rosetting reaction (DARR): sensitive tests for demonstration of immunoglobulin-bearing B lymphocytes

The technology of the mixed antiglobulin rosetting (MARR) and the direct antiglobulin rosetting reaction (DARR) is reviewed. These tests have been found to be more sensitive than the standard direct immunofluorescence (DIF) method for delineation of Ig-bearing B lymphocytes and to have practical advantages over DIF. Further, with these rosette tests, an important B lymphocyte population has been identified which is Ig-negative by DIF and functionally quite different from typical DIF-positive B lymphocytes but which expresses a low density of surface membrane Ig that is detectable by the MARR and the DARR.

Alteration of early T lymphocyte count in patients with herpes genitalis

Peripheral blood samples from 52 women, including 16 with herpes genitalis and 36 healthy persons, were studied to enumerate subpopulations of lymphocytes. It was found that the mean percentage of 'active' T lymphocytes was significantly less in the patients with herpes genitalis than in the controls.
