Tools to Support Clinical Research
For over 30 years, BD has supported the work of clinical researchers who have made significant contributions to the advancement of clinical medicine. Continuing its long-standing commitment, today BD Biosciences instruments and reagent products support a range of efforts to better understand the complexities of the human immune system in healthy and disease states and ultimately progress the standards of human care.
BD Biosciences products support a broad range of immunophenotyping and intracellular staining reagents for blood cell disorders and tools for the study of cell cycle, proliferation, and cell death.
Oncology, the study of cancer, is a complex area of human disease with many challenges including heterogeneity of disease and limited samples. Throughout the world, BD Biosciences tools help clinical researchers study genes, proteins, and cells to better understand disease, improve diagnosis and disease management, and facilitate the discovery and development of novel therapeutics. BD Biosciences clinical oncology research solutions range from antibodies to cellular markers for isolation of specific subpopulations, and determination of cytokine expression, transcription factors, and phosphorylation status.
Blood Cell Disorder Research
Leukemias are cancers of the blood or bone marrow characterized by an abnormal proliferation of blood cells, usually white blood cells (leucocytes). Leukemia is a broad term covering a spectrum of diseases. In turn, it is part of the even broader group of diseases called hematological neoplasms. BD Biosciences supports leukemia clinical research with a broad range of immunophenotyping and intracellular staining reagents for flow cytometry applications to support scientists looking to understand the biological aspects of these cellular abnormalities. Of particular interest to clinical researchers is the exploration of signaling pathways in leukemic cells and the role of stem cells in blood cancers.
Acute Lymphocytic Leukemia (ALL) research
ALL is a cancer of the blood in which too many lymphocytes, a type of white blood cell, are produced by the bone marrow and by organs of the lymph system.
Acute Myeloid Leukemia (AML) research
AML, also called granulocytic, myelocytic, myeloblastic, or myeloid leukemia, is a cancer of the blood in which too many granulocytes, a type of white blood cell that normally fights infection, are produced in the bone marrow. In addition to overpowering other important cells, these over-produced granulocytes do not mature correctly.
Chronic Lymphocytic Leukemia (CLL) research
CLL is a cancer of the blood in which too many lymphocytes, a type of white blood cell, are produced by the bone marrow and by organs of the lymph system. Normally, the lymphocytes fight infection by making antibodies that attack harmful elements. But in CLL, the cells are immature and overabundant. They crowd out other blood cells, and may collect in the blood, bone marrow, and lymph tissue.

Cell Cycle, Proliferation, and Cell Death Research
Cell cycle, proliferation, and cell death play important roles in development and tissue homeostasis. Apoptosis, or programmed cell death, is of particular importance in cancer research. The ability of cells to escape normal apoptotic pathways leads to a survival advantage for malignant cells. In contrast, too much apoptosis contributes to neurodegenerative diseases such as Alzheimer’s disease and Parkinson’s disease. BD Biosciences tools for the study of cell cycle, proliferation, and cell death include BD Pharmingen™ Annexin V kits, BD Phamingen BrdU kits, and antibodies to cyclins and activated caspases optimized for use on BD flow cytometry systems.
Tools that assist your research on infectious diseases such as HIV/AIDS and vaccine development including our patented antigen-specific T-cell response assays.
Today BD Biosciences reagents and flow cytometry systems are helping scientists understand the intricacies of human immune function. The human immune system’s response to infectious agents is key to understanding the mechanisms of infection and host response variability and of intense interest to clinical researchers who hope to use this information to inform better treatment and vaccine strategies. BD Biosciences supports a wide range of efforts to understand infectious disease including the devastating diseases caused by HIV infection.
Products for HIV/AIDS Research
Human immunodeficiency virus (HIV) is a retrovirus that can lead to acquired immune deficiency syndrome (AIDS), a condition in humans in which the immune system begins to fail, leading to opportunistic infections. HIV primarily infects helper T cells (specifically CD4 + T cells and CD8 + T cells), macrophages, and dendritic cells. HIV infection leads to low levels of CD4 + T cells and an inversion of the CD4/CD8 ratio, through three main mechanisms: direct viral killing of infected cells, increased rates of apoptosis in infected cells, and killing of infected CD4 + T cells by CD8 cytotoxic lymphocytes that recognize infected cells. When CD4 + T cell numbers decline below a critical level, cell-mediated immunity is lost, and the body becomes progressively more susceptible to opportunistic infections.

The goal of vaccination is to prime the immune system against a specific target so that a pool of antibody and memory cells can rapidly expand upon renewed contact with the antigen. This ‘primed’ state thus protects the host against infection. BD Biosciences tools that can assist in vaccine research and clinical trials include our patented assays for antigen-specific T-cell responses via multicolor flow cytometry or traditional ELISPOT. In addition, a variety of BD reagents and intracellular cytokine staining protocols are available to characterize the quality of immune response. BD Lyoplate™ and standardization program services available via the BD Custom Technologies Team offer clinical researchers powerful ways to reduce data variability in their flow cytometry experiments, boosting data quality and consistency in longitudinal and multi-site clinical trials.

Leading-edge inflammatory cytokine and chemokine detection assays.
Autoimmunity is the failure of an organism to recognize its own constituent parts as self, which results in an immune response against its own cells and tissues. Any disease that results from such an aberrant immune response is termed an autoimmune disease. Prominent examples include multiple sclerosis (MS), rheumatoid arthritis (RA), Crohn’s disease, type I diabetes, and lupus. BD Biosciences supports autoimmune clinical research with a broad range of reagents for flow cytometry applications to help scientists understand the intricacies of human immune function. This research area has given rise to many exciting new areas of study, such as Th17 and regulatory T cells (Tregs), that may hold important clues to our understanding of autoimmunity-related diseases.
Products for Multiple Sclerosis Research
MS, also known as disseminated sclerosis or encephalomyelitis disseminata, is an autoimmune condition in which the immune system attacks the central nervous system, leading to demyelination. It has been reported that MS patients may have a reduced number of whole (or subsets of) regulatory T cells, (such as CD39 positive) and abnormal levels of Th17 cells.

Products for Crohn’s Disease Research
Crohn’s disease is an autoimmune disease of the gastrointestinal tract resulting in inflammation, abdominal pain, and weight loss. While the exact defect in immune function is not yet defined, several have been proposed including over-reactive-Th1 cytokine response, impaired innate immunity, and defects in Th17. Active Crohn’s disease has been associated with increases in IL-17F gene expression. Tools for the study of Crohn’s disease include kits to measure cytokine levels (CBA), antibodies to cytokines, and antibodies, kits, and cocktails for the phenotyping of T cells.
Products for Arthritis Research
RA is a chronic inflammatory disease characterized by joint inflammation and bone and cartilage erosion. Cytokines produced by infiltrating activated macrophages and T cells are involved in osteoclast-mediated bone resorption. Using BD Biosciences antibodies and kits including antibodies to cytokines and T-cell markers, infiltrating cells such as Th17 and regulatory T cells can be identified and cytokine levels can be measured.

Powerful tools to study Tregs, cytokines, and markers of suppression.
Transplantation is a life-saving procedure for many pathological conditions. Control of the immune system is essential for the prevention of tissue graft rejection. Immune suppression can make patients more vulnerable to infection. In a bone marrow transplant, a new immune system is reconstituted. However, if the transplanted bone marrow is not matched, it can lead to the immune system attacking the host, or graft-versus-host disease (GVHD).
BD Biosciences has many tools to assist in transplantation research that include markers of stem cell differentiation such as CD34 and hematopoietic stem cell identification and isolation kits, as well as tools for the study of cellular immunity such as effector and regulatory T cell markers.

Tools to study the immune system's key role in cardiovascular disease.
Inflammation mediated by the secretion of cytokines such as TNF, IFN-γ, and IL-2 has been shown to be a contributing factor to congestive heart failure, atherosclerosis, and transplant rejection. Th17 (IL-17 secreting T cells) may also contribute to cardiovascular disease. The scavenger receptor, CD36, is reported to be involved in vascular cell inflammation and atherosclerosis. To support this evolving area of research, BD Biosciences has tools such as Cytometeric Bead Arrays (CBA kits) for the measurement of multiple cytokines within a single sample, as well as antibodies and panels for the phenotyping of infiltrating immune cells.
