PepMix™ Peptide PoolsThe use of complete protein-spanning mixtures of overlapping peptides (PepMix) is extremely efficient for immunostimulation of T-lymphocytes and diagnostic applications. In order to establish reliable and validated T-cell assays such as ELISPOT, appropriate positive and negative controls are essential. Selection of such controls helps to confirm proper functionality of the assay as well as viability of the cells used. In addition, high quality controls are most important to establish standardized assay protocols in clinical setups. Compared to commonly used controls like phytohemagglutinin (PHA) and concanavalin A (ConA) that stimulate T-cells as well as other cell types or full length antigens, synthetic peptide pools offer the advantage of a high batch-to-batch reproducibility, applicability of reliable chemical and biochemical QC/QA measures and shelf stability when stored as freeze dried aliquots.

Benefits of PepMix™- Equivalent or better stimulation of CD4⁺ and CD8⁺ T-cell responses compared to whole protein antigens- Simultaneous detection of CD4⁺ and CD8⁺ responses in a single sample - Improved responses in stored blood and PBM cells compared to whole protein antigens- More reliable as control than phytohemagglutinin (PHA) and concanavalin A (ConA) - High-batch-to-batch reproducibility- Reliable chemical and biochemical quality control and quality assurance for peptide synthesis and peptide pool generation- Prolonged shelf stability when stored freeze dried

Testimonials \"To establish a novel role for myeloid derived suppressor cells (Pallett et al, Nat. Med. 2015) in chronic viral infection, we utilised the PepMix CEF Pool (extended) as well as a custom synthesized PepMix spanning the core region of HBV genotype D . Whereas, the CEF peptide pool consists of 32 peptides, each corresponding to a defined HLA class I-restricted T-cell epitope from Cytomegalo, Epstein-Barr, and Influenza virus, the latter custom PepMix included 15meric peptides overlapping by 10 amino acids. Specifically this composition enabled us to monitor both the antiviral CD8+ and CD4+ T cell responses in chronic HBV infection and the non-antigen specific T cells that are known to mediate immunopathology in the liver. Our entire experience with JPT, from ordering/delivery to use in the lab was excellent. Not only were the reagents able to perform reliably and consistently in vitro from batch to batch, the customer and technical support provided was continually available and efficient when needed. JPT will remain our \"go-to\" company for purchasing peptides.\" Dr. Laura J Pallett, Infection and Immunity, University College London, UK
