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 TestingEach batch is regularly tested via ELISpot assays on two donors. Your Benefits:
- Assay standardization & validation
- Minimized performance variability
- Updated Certificate of analysis (CoA)
- Cytotox TestingEach batch is tested in an in vitro Resazurin-based assay to determine if the dissolved peptides show cytotoxic effects.
- Endotoxin TestingPh. Eur.2.6.14A LAL test or Haemotox rFC test are performed with each batch to detect endotoxins.
- Sterility TestingPh. Eur.2.6.1Each 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 PoolsProtein-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™
