Influenza Matrix Protein (61-72) is a peptide derived from the matrix protein of influenza viruses, encompassing amino acids 61-72, and has the ability to elicit a CD4+ T-cell response.

Influenza HA (110-119) refers to a specific fragment (110-119) derived from the hemagglutinin protein of the influenza virus. This fragment has the ability to induce the proliferation of Treg cells.

NS2 (114-121), Influenza, is a fragment derived from the nonstructural protein 2 (NS2) of the influenza virus, serving as an epitope for influenza research and useful for studying CD8+ cytotoxic T lymphocyte (CTL) responses in antiviral immunity.

Influenza HA (518-526) is an immunodominant epitope in H2d mice post flu virus infection.

[HLA-B*3501 restricted influenza virus nucleoprotein epitope (383-391).]

HLA-B*08 restricted influenza virus nucleoprotein epitope.

This peptide is a H2-Db-restricted epitope from Influenza nucleoprotein (147-155).

This peptide is an H2-Db-restricted epitope from the Influenza A/PR/8/34 nucleoprotein.

This peptide is a H-2Kd-restricted epitope from Influenza nucleoprotein (147-155).

CEF1, Influenza Matrix Protein M1 (58-66), is an epitope derived from the matrix protein of the influenza A virus. GILGFVFTL is an HLA-A2-restricted epitope from this matrix M1 protein.

Influenza HA (126-138) is a peptide derived from the hemagglutinin (HA) protein of the influenza virus, consisting of amino acids 126-138, and has the ability to induce apoptosis in both thymic and peripheral T-cells.

Influenza HA (307-319) acetate is the 307-319 amino acid fragment of the influenza virus hemagglutinin (HA) protein, an HLA-DRB1 0101-restricted epitope polypeptide with the sequence PKYVKQNTLKLAT, which can be used for the study of influenza virus immunogenicity as well as for the development of vaccines and diagnostic reagents against influenza virus.

Aprotinin (Traskolan) is a broad-spectrum serine protease (BPTI) inhibitor that inhibits the activity of a number of different esterases and proteases. Aprotinin is an antifibrinolytic agent used to minimize hemorrhage during complex surgical procedures.

Urumin, a compound with antiviral properties, inhibits human influenza A virus growth, particularly the PR8 strain, with an inhibitory concentration (IC 50) of 3.8 μM. It acts by targeting the conserved stalk of H1 hemagglutinin and can neutralize drug-resistant H1 influenza viruses. Additionally, Urumin offers protective effects against lethal influenza infection in naive mice [1].

Citrullinated LL-37 3cit is a host defense peptide with notable immunomodulatory and antimicrobial properties, which exhibits direct antiviral activity against human rhinoviruses (HRV) [1].

Influenza A virus-IN-8 (S5), a macrocyclic peptide, exhibits no cytotoxicity and acts as a potent inhibitor of Influenza A Virus (IAV), demonstrating significant protease stability, with IC50 values of 6.7 nM for H1 and 6.6 nM for H5 variants. It has a high affinity for H1 variants, binding to a conserved region in the HA stem with a dissociation constant (Kd) of 1.0 nM [1].

Influenza NP (311-325) is a biologically active peptide consisting of amino acids 311 to 325 from the influenza virus nucleoprotein (NP). As a bona fide MHC class II-restricted epitope, it is critical for studying host immune responses during viral infection, inducing robust gamma interferon (IFN-gamma) production in intracellular cytokine assays without stimulating CD8 T-cells in mice. The presence of Glutamine (Q) or Glutamic acid (E) at the N-terminus can lead to spontaneous formation of Pyroglutamyl (pGlu) peptides, enhancing peptide stability against gastrointestinal proteases. These peptides are considered a normal variant and included in peptide purity measurements in HPLC analysis.

Influenza HA (110-119) acetate is the 110-119 fragment of influenza virus hemagglutinin that can stimulate Treg cells proliferation[1][2].

Influenza Hemagglutinin is an HLA-DRB 0101-restricted epitope from influenza hemagglutinin (307-319).
