BD Biosciences contributions in CD4 counting and immune status for HIV/AIDS

Abstract
BD Biosciences is a leader in the use of flow cytometry for determining immune system status and for counting CD4 cells in patients with human immunodeficiency virus (HIV) infection. The company has gained this position through many years of basic research and product development in immunology and cell biology, dye chemistry, immunoassays, instrumentation, and software. Some of the highlights of these developments and their historical perspective are described in this review. Cytometry (Clin. Cytometry) 50:129–132, 2002.
