cd9-tetraspanin-peptide The CEF peptide pool is a crucial reagent in immunology, widely recognized for its utility as a positive control in various T-cell based assays. This specialized peptide pool is a meticulously prepared mixture designed to stimulate specific immune responses, particularly from CD8 T cells. Its composition and application are central to understanding cellular immunity against viral infectionsPepPool: CEF (CD8), human.

At its core, the CEF peptide pool is defined by its constituent peptides, which are derived from common human virusesCEF Pool (extended) ; Catalogue number: · PM-CEF-E-4 ; Supplier: JPT Peptide Technologies ; Size: 120 nmol /peptide.. The most prevalent formulations of the CEF peptide pool consist of 32 peptides or 23 peptides.The CEF (HLA Class I Control) Peptide Pool is alyophilized mixture of 32 peptidesfrom cytomegalovirus (CMV), Epstein-Barr virus (EBV), and influenza virus. These peptides are typically 8-12 amino acids in length and are known to be HLA class I-restricted T-cell epitopes32 HLA class I-restricted T cell epitopes from Cytomegalovirus, Epstein-Barr virus, and Influenza virus. Positive control for CD8 cell activation.. This means they are recognized by T cells in conjunction with specific major histocompatibility complex (MHC) class I molecules, a fundamental aspect of adaptive immunity.

The viral origins of these peptides are consistently cited as Cytomegalovirus (CMV), Epstein-Barr virus (EBV), and influenza virus. These viruses are chosen due to their high prevalence in the human population and their ability to elicit robust T-cell responses.TheCEF extended peptide poolinduces secretion of e.g., IFN-γ, IL-2, and granzyme B from human CD8 T cells. It consists of 32 MHC class I-restricted viral ... The specific peptides within the CEF peptide pool are selected to represent common and immunogenic epitopes from these pathogensThepoolconsists of defined HLA class I-restricted T cell epitopes from these three viruses, and can be used as a positive control to stimulate T cells..

The primary application of the CEF peptide pool is as a positive controlPharmaOnco™ CEF-HLA I Control Peptide Pool, 32 peptides. This is particularly true for assays designed to detect antigen-specific CD8+ cells and to assess CD8 T cell activation. When researchers are investigating immune responses to viral infections or developing new immunotherapies, it is essential to have a reliable method to confirm that their experimental setup is functioning correctly.作者：A Schiller·2017·被引用次数：19—TheCEF peptide pool consisting of 32 HLA Class 1-restricted peptides[1] widely used as a positive control for CD8 cell activation, was ... The CEF peptide pool provides this by reliably inducing a known immune response.The CEF peptide poolis extensively used as a positive control for CD8 T cell activation. Peptides from the CEF pool causes CD8+ T cells to produce various ... For instance, it is extensively used as a positive control for CD8 T cell activation.

The mechanism by which the CEF peptide pool elicits this response involves stimulating the secretion of key cytokines and effector molecules associated with T-cell activity. These include IFN-γ (interferon-gamma), IL-2 (interleukin-2), and granzyme B. The detection of these molecules serves as a quantifiable measure of T-cell activation and function. Consequently, the CEF peptide pool is valuable for techniques such as intracellular flow cytometry analysis.

Different variations of the CEF peptide pool exist, often distinguished by the exact number of peptides or specific formulations. For example, some products are referred to as CEF-MHC Class I Control Peptide Pool "Classic" and typically contain 23 peptides. Other versions, such as the CEF-MHC Class I Control Peptide Pool "Plus" or CEF Pool (extended), often comprise 32 peptides. These "Plus" or "extended" versions may offer broader coverage of epitopes or be optimized for specific experimental conditions. The CEF extended peptide pool is designed to stimulate specific T-cell responses.

The physical form of the CEF peptide pool is also noteworthy. It is commonly supplied as a lyophilized mixture, meaning it has been freeze-dried for stability and ease of storage and transport. Users will reconstitute the lyophilized powder with an appropriate solvent before useMHC I / MHC II Control. This lyophilized mixture of 32 peptides or lyophilized mixture of 23 peptides ensures the integrity and potency of the peptides until they are needed for an experimentCEF Control Peptide Pool HLA Class I PLUS.

The CEF peptide pool is a standardized and well-characterized tool that contributes significantly to the reliability and reproducibility of immunological research. Its ability to act as a specific positive control for T-cell responses against common viral pathogens makes it indispensable for researchers in virology, immunology, and cancer immunotherapy.32 HLA class I-restricted T cell epitopes from Cytomegalovirus, Epstein-Barr virus, and Influenza virus. Positive control for CD8 cell activation. The pool of 32 HLA class I-restricted T cell epitopes or its counterpart with 23 peptides provides a consistent benchmark for assessing T-cell functionality and for validating experimental findings.CEF control Peptide Pool (>95% HPLC, advanced) The CEF and CEFT pools are ideally suited for use as specific positive controls in all T-cell-based assays. The CEF-HLA I Control Peptide Pool is recommended as the positive control for detecting antigen-specific CD8+ cells in human PBMC. Ultimately, the CEF peptide pool empowers scientists to gain deeper insights into the complexities of the immune system.
