Furthermore, we provide cell-based or non cell-based binding assays for the Fcg Receptors CD16a, CD16b, CD32a, CD32b, CD64 and FcRn as well as C1q. The Cellular Immunology Submission Guidelines for Assay Approval (CLEP webpage under Test Approval) provides guidance for specimen number and requirements. This will include the use of multiple-parameter flow cytometry and other cell-based assay techniques. Our Cellular Immunology Service includes but is not limited to: Immunophenotyping and functional analysis of immune cells is a key expertise of IBR Inc. We perform assays with whole blood, PBMCs and isolated immune cell subsets to analyze intracellular and surface marker expression and immune cell function: apoptosis, phagocytosis and cytotoxicity, immune cell proliferation and cytokine quantification (multiplex BD™ Cytometric Bead Array, CBA). PBMC’s) human complement is used to initiate the killing. Amongst these are Antibody Dependent Cellular Cytotoxicity (ADCC ) and Complement Dependent Cytotoxicity (CDC). CTL assays are commonly used to quantify cytotoxicity, particularly in the study of tumor and viral cytolysis. For CDC, these assays are set up very similar to the above mentioned ADCC assays using FACS as a readout. We leverage this knowhow to offer a variety of assays to assess cellular immunology in-vitro. Washed out of mitochondria after fixation. in the ECL assay is that the assay captures all of the immunoglobulin classes: IgG, IgM, IgA, and IgE. immune cell proliferation, target specific cell-death, cytokine measurement (intra-or extracellular), expression of activation/exhaustion markers and phenotypic characterization of lymphocyte subsets. In both cases, Aragen has significant experience with a broad diversity of target cells and mechanisms of killing. CD8 cell activation, cellular lysis) can be confusing. HTRF, Luminex and ELISpot are a plus In addition to standard flow cytometry, Aragen has the capability of high-throughput 4-color flow cytometry (with the IntelliCyt iQue system) for many single and multiplexed assays. Feel free to contact us with our custom assay development needs. Assays for Today’s Immunology Research This era of immunology holds great promise for the development of new treatments for cancer, immune dysfunction, and infectious disease. IBR Inc. interrogates 3D cellular models to study how immune cells tackle the challenge of infiltrating solid tumor mass, that can be mimicked by complex 3D spheroids composed of different cell types. Our assays are designed to ensure consistency and … However, various sources of PBMC’s (e.g normal vs diseased donors) can also be sourced. The Enzyme-Linked ImmunoSpot (ELISpot) assay evaluates the response of specific immune cells to a certain stimulus by measuring both the quantitative frequency of positive-responding cells, as well as the qualitative characterization of secretion of specific cytokines or other secreted immune molecules by those responding cells. For the evaluation of the immune cell function we are capable to use multiple readouts e.g. The assays, reagents, technology, and education offered by the Core support CFAR research involved with the prevention, detection, and treatment of HIV infection and AIDS. The Immunology Core provides advanced tools and training for evaluating humoral and cellular responses to HIV infection. JC-1 assay ab113850 / JC-10 assays ab11213… This mTNFα molecule can bind antibodies and provides a readout for the induction of ADCC and CDC activity. CD3/CD28 or anti-IGM). The protection from viral infections and cancers often occurs through Cytotoxic T lymphocyte (CTL) responses. CETSA is a biophysical assay based on the principle of ligand-induced thermal stabilization of target proteins, meaning that a proteins melting temperature will change upon ligand interaction. We invite you to discuss your specific needs with us in order to provide you with a solution tailored to your needs. Research Assistant – Immunology / Serology. Aragen’s preferred readout for this assay is a FACS-based method, although alternative methods (e.g. The Oncomine TCR Beta-LR Assay, provides researchers with a rapid, long-read NGS tool for studying the complexity of cellular immunology. However, instead of using effector cells (e.g. The immune cell activation upon treatment with anti-cancer therapeutic agents including T-cell bispecific antibodies (TCBs), Antibody-Drug-Conjugates (ADCs), immunocytokines, checkpoint inhibitors, immunomodulators and antibodies with enhanced effector function can be assessed in-vitro on human whole blood, PBMCs or isolated immune cell subsets. Assays of Cellular Immunology • DTH –“red bump in the skin” • Most cellular assays depend on density separation of “PBM” – peripheral blood mononuclear cells Cited ~14,000 times! The co-transcription of WC1 genes showed that WC1s can be expressed by themselves or in combinations with some overlap between the two subsets. Our scientists have expertise in performing assays in whole blood, PBMCs and purified immune cell subsets. Recently our group introduced a new method to meet this challenge: the Cellular Thermal Shift Assay (CETSA) (Science 341(6141):84-87). This method can therefore be used to measure cytotoxicity, proliferation or activation. Simply fill out the form below and a member of our team will follow up with you shortly. Each spot corresponds to an individual cytokine-secreting cell. Evaluating potential new targets via in silico-based approaches. IBR Inc. has 20 years of expertise in cell-based assays. Enzyme-linked immunospot (ELISpot) assays are highly sensitive immunoassays that measure the frequency of individual cytokine-secreting cells. viral infection, tumors, etc.). Dr. Robert Hall, MD is a board certified internist in Griffin, Georgia.
