CEF Control Pep Pool 25ug/pep

A lyophilized mixture of 32 peptides from cytomegalovirus (CMV), Epstein-Barr virus (EBV), and influenza virus, supplied by STEMCELL Technologies. The pool consists of defined HLA class I-restricted T cell epitopes from these three viruses and serves as a positive control for stimulating T cells in immunological assays, supporting applications such as vaccine development and immune cell monitoring.

The product is supplied at ~25 µg (15 nmol) per peptide at ≥95% purity, lyophilized as trifluoroacetate salts, and is sufficient for stimulating 2.5 x 10^8 cells. To prepare, warm to room temperature (15–25°C), add pure dimethyl sulfoxide (DMSO; ~40 µL), and dilute with water to the desired concentration. A final concentration of ≥1 µg/mL per peptide is generally recommended for antigen-specific stimulation, with the final DMSO concentration kept below 1% (v/v) to avoid toxicity in the biological system.

Store at -20°C; the product is stable as supplied until the expiry date on the label. If not used immediately, aliquot and store at -20°C, protect from light, and avoid repeated freeze-thaw cycles. For research use only.
