CD100 Human HEK
CD100 Human Recombinant HEK
CD160 Human
CD160 Human Recombinant
Recombinant human CD160, produced in Sf9 Baculovirus cells, is a single, glycosylated polypeptide chain. It consists of 142 amino acids (specifically, residues 27 to 159a.a.) and has a molecular weight of 15.9 kDa. However, it's important to note that on SDS-PAGE analysis, the apparent molecular size will be approximately 18-28 kDa. This discrepancy is attributed to glycosylation. The CD160 protein is engineered to include a 6-amino acid His tag at its C-terminus to facilitate purification, which is achieved through proprietary chromatographic techniques.

Introduction
Cluster of Differentiation (CD) antigens are cell surface molecules expressed on leukocytes and other cells involved in the immune response. They are used as markers to distinguish between different cell types and states. “Other CD antigens” refer to those CD molecules that are less commonly studied or have more specialized roles compared to the well-known CD markers like CD4 or CD8. These antigens are classified based on their molecular structure and function.
Key Biological Properties: CD antigens are glycoproteins or glycolipids that play crucial roles in cell signaling, adhesion, and immune response modulation. They exhibit diverse structural features, including single-pass transmembrane domains, extracellular domains, and cytoplasmic tails.
Expression Patterns: The expression of CD antigens varies among different cell types and tissues. Some CD antigens are ubiquitously expressed, while others are restricted to specific cell lineages or activation states.
Tissue Distribution: CD antigens are distributed across various tissues, including lymphoid organs (e.g., thymus, spleen, lymph nodes), peripheral blood, and non-lymphoid tissues (e.g., skin, liver, lungs).
Primary Biological Functions: CD antigens are involved in a wide range of biological functions, including cell-cell communication, antigen presentation, and immune cell activation. They serve as receptors or co-receptors for signaling molecules, facilitating the transmission of extracellular signals to intracellular pathways.
Role in Immune Responses: CD antigens play critical roles in the initiation and regulation of immune responses. They are involved in the recognition of pathogens, activation of T and B cells, and modulation of immune cell interactions.
Pathogen Recognition: Certain CD antigens act as pattern recognition receptors (PRRs) that detect pathogen-associated molecular patterns (PAMPs) on microbes, leading to the activation of innate immune responses.
Mechanisms with Other Molecules and Cells: CD antigens interact with a variety of ligands, including other cell surface molecules, soluble factors, and extracellular matrix components. These interactions are essential for cell adhesion, migration, and signaling.
Binding Partners: CD antigens bind to specific ligands, such as cytokines, growth factors, and adhesion molecules. These binding events trigger downstream signaling cascades that regulate cellular functions.
Downstream Signaling Cascades: Upon ligand binding, CD antigens initiate intracellular signaling pathways that involve protein kinases, phosphatases, and adaptor proteins. These cascades lead to changes in gene expression, cytoskeletal rearrangements, and functional responses.
Regulatory Mechanisms that Control Expression and Activity: The expression and activity of CD antigens are tightly regulated at multiple levels, including transcriptional, post-transcriptional, and post-translational mechanisms.
Transcriptional Regulation: The transcription of CD antigen genes is controlled by transcription factors, enhancers, and promoters. Epigenetic modifications, such as DNA methylation and histone acetylation, also influence gene expression.
Post-Translational Modifications: CD antigens undergo various post-translational modifications, including glycosylation, phosphorylation, and ubiquitination. These modifications affect their stability, localization, and functional activity.
Biomedical Research: CD antigens are widely used as markers in immunophenotyping, flow cytometry, and cell sorting. They help identify and isolate specific cell populations for research and clinical applications.
Diagnostic Tools: CD antigens serve as diagnostic markers for various diseases, including cancers, autoimmune disorders, and infectious diseases. They are used in immunohistochemistry and immunoassays to detect and quantify specific cell types.
Therapeutic Strategies: CD antigens are targets for therapeutic interventions, such as monoclonal antibodies and chimeric antigen receptor (CAR) T-cell therapies. These strategies aim to modulate immune responses and treat diseases like cancer and autoimmune conditions.
Role Throughout the Life Cycle: CD antigens play essential roles throughout the life cycle, from development to aging and disease. During development, they are involved in cell differentiation, tissue formation, and immune system maturation.
Development: CD antigens are critical for the development and maturation of immune cells, including T cells, B cells, and dendritic cells. They guide cell fate decisions and functional specialization.
Aging and Disease: The expression and function of CD antigens change with aging, contributing to age-related immune dysfunction. Dysregulation of CD antigens is associated with various diseases, including cancers, autoimmune disorders, and infectious diseases.
