Description

The CEF peptide pool is a lyophilized mixture of 23 peptides from cytomegalovirus (CMV), Epstein-Barr virus (EBV), and influenza virus. It consists of defined HLA class I-restricted T cell epitopes from these three viruses. The CEF peptide pool is used as a positive control to stimulate T cells. It induces secretion of e.g., IFN-γ, IL-2, and granzyme B from human CD8 T cells.

The peptides of this product are supplied as trifluoracetate salts.

One unit allows the stimulation of 2,5 x 10⁸ cells.

Actin Peptide Pool, human

The HUMAN (Actin) Peptide Pool consists of 92 overlapping peptides derived from a peptide scan through Actin, alpha skeletal muscle (UniProt ID: P68133) of Homo sapiens. The peptides are 15mers that overlap by 11 amino acids. One unit of HUMAN (Actin) Peptide Pool allows the stimulation of 2,5 x 108 cells. Actin is a ubiquitously expressed protein and therefore an excellent negative control for T cell assays. Relevant controls are critical for measuring antigen-specific responses as they allow accurate interpretation of test results. The HUMAN (Actin) Peptide Pool can rule out non-specific binding of peptides to the tested T cells, while a negative control with medium detects general background signals. Examples of publications where actin was used as a negative control: Baker FL, et al.: Exercise mobilizes diverse antigen specific T-cells and elevates neutralizing antibodies in humans with natural immunity to SARS CoV-2.

B8R 20-27 (H-2 Kb)

The linear peptide B8R 20-27, with the amino acid sequence TSYKFESV (epitope ID 66504), is a well-established H2-Kb-restricted epitope conserved among various Vaccinia virus strains. [1] It is part of the: Soluble interferon gamma receptor OPG193 (UniProt:P24770) from Vaccinia virus IFN-gamma receptor (UniProt:Q66793) from Ectromelia mousepox virus IFN-gamma receptor-like protein (UniProt:G0XTP5) from Cowpox virus The Vaccinia virus was the live vaccine used to eradicate smallpox. It belongs to the orthopoxvirus family and provides protection against a range of orthopoxviruses. Currently, the most concerning of these is the monkeypox virus, but human cowpox infections are also being reported regularly in Europe. [1] The B8R 20-27 peptide, TSYKFESV, is also contained in recombinant and non-recombinant Modified Vaccinia virus Ankara (MVA). [1] The Modified Vaccinia virus Ankara has greatly reduced virulence and can no longer replicate in most mammalian cells. [2] It is often used as a vaccine vector, due to its cost-effectiveness, safety, and high immunogenicity. Recombinant MVA vaccines can generate robust humoral and cellular immune responses against various pathogens. In vaccine development, the B8R 20-27 peptide is used as a positive control to demonstrate that a lack of response is not due to immunization failure. The vaccinia virus B8R gene encodes a homolog of the secreted IFN-γ receptor. By binding to IFN-γ, B8R neutralizes its antiviral activity and is therefore involved in virus evasion of host interferon responses.
