Premium Grade Quality PepMix™

For applications where performance, reproducibility, and stability are critical, our new Premium Grade PepMixes™ feature multiple layers of ongoing quality control:

  • Recurrent Performance Testing
    Each batch is regularly tested via ELISpot assays on two donors.
    Your Benefits:
    • Assay standardization & validation
    • Minimized performance variability
    • Updated Certificate of analysis (CoA)
  • Cytotox Testing
    Each batch is tested in an in vitro Resazurin-based assay to determine if the dissolved peptides show cytotoxic effects.
  • Endotoxin Testing
    Ph. Eur.2.6.14
    A LAL test or Haemotox rFC test are performed with each batch to detect endotoxins.
  • Sterility Testing
    Ph. Eur.2.6.1
    Each batch is incubated in tryptic soy broth. Later turbidity is determined as indicator of contaminating microorganisms.
  • Plus, our trusted quality benchmarks still apply
    • > 90% Purity of each peptide in the pool (via HPLC-MS)
    • Validated pooling method ensuring the presence of each peptide
    • Produced under stringent quality management
    • CoA and HPLC-MS data available for each individual peptide batch
    • Avoiding false positive T-cell responses by contaminating deletion peptides
    • ADCF policy

PepMix™ Peptide Pools
Protein-spanning mixtures of overlapping peptides (PepMix™) are extremely efficient for
- Antigen-specific T cell stimulation in T cell assays (e.g. in ELISpot, ICS, cell-mediated cytotoxicity or proliferation assays)
- In-vitro T cell expansion
- Dendritic cell pulsing
- Immune monitoring
- Cellular immune response profiling
- T cell epitope identification
- Standardization of T cell assays

Benefits of PepMix™
- Each peptide quality controlled and guaranteed for identity and purity
- CoA and HPLC-MS data available
- High batch-to-batch consistency
- No false positive T cell responses by contaminating deletion peptides
- No toxic inhibition of T cell responses due to stringent purification of each peptide
- Minimization of endotoxin contamination due to low bioburden process
- ADCF policy in place
- HLA independent stimulation (with antigen spanning peptide pools)

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."
