Stimulating T cells with HIV (HLA Class I Control) Peptide pool releases downstream cytokines and upregulates activation markers, enabling antigen-specific T cells to be detected or isolated for analysis. HIV Peptide pool is a lyophilised mixture of 22 peptides from human immunodeficiency virus (HIV), and consists of defined HLA class I-restricted T cell epitopes. Viral peptide pools are useful for a broad range of applications, including vaccine development, immunological research, and diagnostic assay development.

Stimulating T cells with HIV-1 (B Gag) peptide pool releases downstream cytokines and upregulates activation markers, enabling antigen-specific T cells to be detected or isolated for analysis. HIV-1 (B Gag) Peptide Pool is a lyophilised mixture of 123 peptides from the gag polyprotein of human immunodeficiency virus 1 (HIV-1). The pool consists of 15-mer peptides with 11-amino-acid overlaps that cover amino acids 1 to 500 on gag polyprotein. The HIV-1 gag polyprotein is a key mediator of viral particle assembly (Campbell and Rein; Dong et al.), and together with the endosomal sorting complexes required for transport (ESCRT), results in budding during virion release (Carlson et al.). Viral peptide pools are useful for a broad range of applications, including vaccine development, immunological research, and diagnostic assay development.

SARS-CoV-2 Recombinant Nucleocapsid Protein, aa1-419 is expressed in E. coli and is one of four structural proteins encoded by the SARS-CoV-2 genome. The Nucleocapsid Protein is transcribed from the viral “N” gene and is the protein that interacts with RNA to form the nucleocapsid. The protein is a homo-oligomer, and both the monomer and the oligomer can interact with RNA. This protein also interacts with the membrane protein (protein M) after infection of the host cell during packaging of the positive-strand viral genome RNA into the ribonucleocapsid during virion assembly. At the amino terminus, SARS-CoV-2 Recombinant Nucleocapsid Protein contains a thrombin site, a T7 tag, and a polyhistidine tag.

Interleukin 22 (IL-22) is a class 2 α-helical cytokine that signals through the class 2 cytokine receptor and activates the JAK/STAT pathway. IL-22 is secreted by Th1, Th2, Tc22, and γδ T cells, dendritic, mast and NK cells. It stimulates expression of antimicrobial peptides from epithelial cells, thus hindering bacterial infections. Depending on the interactions with other cytokines, IL-22 can either promote inflammation or prevent tissue destruction by regulating host defense and tissue homeostasis at barrier surfaces (Sonnenberg et al.).

Chemokine ligand 19 (CCL19), also known as macrophage inflammatory protein-3 beta (MIP-3β), is a member of the CC chemokine family, which plays key roles in inflammatory responses, T cell activation, homeostasis, and development (Yan et al.). CCL19 is expressed in lymph nodes, thymus, and activated bone marrow stromal cells; it binds to C-C motif chemokine receptor 7 (CCR7) to induce migration of macrophages, T cells, and B cells (Gibejova et al.). Clinically, the expression of CCL19 is correlated to autoimmune diseases such as rheumatoid arthritis and cancer (Pickens et al.; Zhang et al.).

Growth differentiation factor 5 (GDF-5) is a member of the bone morphogenetic protein (BMP) subclass of the transforming growth factor beta (TGF-β) superfamily. It binds a receptor complex comprising BMPR1B and BMPR2, which then activates the SMAD signaling pathway (Carreira et al.; Nishitoh et al.; Osório et al.). GDF-5 enhances chondrogenic differentiation of mesenchymal stem cells, skeletogenesis, and dendrite growth during development (Coleman et al.; Francis-West et al.). Studies in rat demonstrated that GDF-5 regulates patterning, neurogenesis, astrogliogenesis, and neuronal specification (Gajavelli et al.; Krieglstein et al.; O’Keeffe et al.).

Transforming growth factor (TGF) beta 2 is a member of the TGF-β superfamily and regulates diverse cellular phenotypes. Similar to TGF-β1 and -β3, TGF-β2 signals via serine-threonine kinase type I and II receptors and activates signal transduction via SMAD family proteins, regulating a variety of functions such as cell proliferation, differentiation, wound healing, apoptosis, and metabolism (de Caestecker; Massague; Zuniga et al.). TGF-β2 is important in many developmental processes; for example, mice with TGF-β2 deletions show defects in the development of cardiac, lung, craniofacial, limb, eye, ear, and urogenital systems (Dunker and Kreiglstein).
