High-Quality CD Proteins for Immunological Research
Cluster of Differentiation (CD) proteins play a vital role in the immune system by acting as cell surface markers that help identify, classify, and understand various immune cells. At Beta LifeScience, we offer a diverse collection of high-purity CD proteins that support immunology research, therapeutic development, and diagnostic applications.
Whether you're studying immune responses, developing monoclonal antibodies, or engineering cell therapies, our CD proteins provide the precision and consistency you need for reliable results.
What Are CD Proteins?
CD proteins—short for Cluster of Differentiation—are molecules found on the surface of immune cells. These proteins function as receptors, ligands, or adhesion molecules, initiating signal cascades that influence cell behavior. By interacting with their specific partners, CD proteins regulate immune cell activation, communication, and migration.
These proteins are especially important in immunophenotyping, where they act as markers to identify cell types and subtypes. For example:
-
CD4 and CD8 mark different subsets of T cells.
-
CD19 is used to detect B cells.
-
CD56 identifies natural killer (NK) cells.
CD molecules provide insights into immune cell function, health, and disease, and are widely used in cancer research, autoimmune disease studies, and vaccine development.

Applications of CD Proteins in Research
Researchers and clinicians rely on recombinant CD proteins for a range of critical applications in both basic science and applied medical research. These include:
Cell Identification and Sorting
CD markers allow for the accurate classification of immune cells in blood, tissue, or cultured samples. Techniques such as flow cytometry and immunohistochemistry depend on CD proteins to detect and sort specific cell populations.
Immune Profiling
Understanding the expression levels of CD proteins can reveal how the immune system is responding to infections, tumors, or therapies. Immune profiling using CD antigens is common in oncology, immunotherapy, and transplant monitoring.
Monoclonal Antibody Development
Many therapeutic antibodies are designed to target CD antigens. Our CD proteins help researchers validate binding affinities, optimize drug designs, and screen for specific interactions.
Cell Therapy and CAR Constructs
CD proteins serve as essential targets and tools in CAR-T and CAR-NK cell therapies. CD19, CD20, and CD22, for instance, are commonly used in targeting B-cell malignancies. By studying CD protein behavior, researchers can refine engineered cell therapies for improved clinical outcomes.
Disease Biomarker Discovery
Changes in CD protein expression can indicate inflammation, infection, or malignancy. This makes CD antigens valuable biomarkers for diagnosing and monitoring a wide array of conditions, from HIV to leukemia.
Choosing the Right CD Protein
Your choice of CD protein depends on the research model, detection technique, and experimental goal. Here are key factors to consider:
- Species Compatibility: Our catalog includes CD proteins from human and key model organisms such as mouse and rat.
- Protein Tag Options: Available in tagged and untagged forms to support purification, detection, and binding studies.
- Functional Activity: Verified bioactivity ensures reliable performance in assays and cell-based systems.
- Application-Specific Forms: Select from soluble extracellular domains, full-length proteins, or engineered variants depending on your project.
