As someone deeply involved in the procurement a CEF Control Peptide Pool, (1 mg) This product contains 0.03 mg (net) of the 32 CEF peptides for a total of 1 mg in one vial. Used in the stimulation of IFNy Read more nd evaluation of high-quality biochemical reagents for laboratory research, I have found that the AnaSpec CEF peptide pool stands out as a standard for consistency and reliability. When navigating the complexities of cellular research, having a dependable positive control is essential for ensuring the validity of experimental workflows.
Technical Specifications and Composition
The AnaSpec CEF Control Peptide Pool is a sophisticated, l Postive Control - CEF Pool (standard) >70% 15 nmol/peptide yophilized mixture of 32 peptides, each carefully selected for its biological significance. These sequences are derived from three major human pathogens: Cytomegalovirus (CMV), Epstein-Barr Virus (EBV), and the Influenza Virus.
Key technical parameters include:
* Structural Characteristics: The pool is comprised of a group of 32 peptides, 8-12 amino acids in length, which are optimized for HLA class I-restricted epitope recognition.
* Formulation Options: Depending on the scale of the experiment, researchers can source the CEF Control Peptide Pool (1 mg), a CEF (HLA Class I Control) Peptide Poolis a lyophilized mixture of 32 peptides from cytomegalovirus (CMV), Epstein-Barr virus (EBV), and influenza virus.Read more n intermediate CEF Control Peptide Pool (8 mg), or the larger CEF Control Peptide Pool 16mg format.
* Standardization: This CEF (HLA Class I Control) Peptide Pool is widely recognized because it co Product Sheet nsists of 32 MHC-1– specific peptides of 8–12 aa in length, ensuring that researchers have a consistent benchmark across different study dates.
The Role of CEF Peptides in Research
In my experience, this reagent represents a vital tool for researchers investigating cellular immune responses, particularly when characterizing CD8+ T cell functionality. Because CEF peptides function by binding to CD8+ T cells, they act as a trigger for interferon-gamma (IFNg) release. This makes the product useful as a peptide-specific positive control in assays such as ELISPOT, CTL, and intracellular cytokine analysis using human peripheral blood mononuclear cells (PBMC).
While some studies focus on cell permeable & penetrating peptides—also known as Protein Transduction Domains (PTDs) which are short peptides that can freely move across cell membranes—the CEF pool is specifically engineered for MHC class I presentation. It is essentially a mixture of 32 peptides that provides a robust, predictable response in standardized immunological assays.
Why Quality Matters in Peptide Synthesis
AnaSpec, based in Fremont, California, manufactures many categories of peptides with decades of expertise in custom syn These 12 Influenza viruspeptides, at 0.25 mg each (total of 3 mg/vial), constitute part of theCEFControlPeptidePool (cat# 61036-025).
