The CMV (pp65) peptide pool is a lyophilised mixture of 138 peptides from the 65 kDa phosphoprotein (pp65) of human cytomegalovirus (CMV; strain AD169). pp65 has been shown to counteract the induction of interferon response by preventing the activation of interferon response factor 3 (IRF-3). pp65 is also important in inducing transcription of viral immediate-early promoter. The pool consists of 15-mer peptides with 11-amino-acid overlaps that cover amino acids 1 to 561 on pp65.

The EBV (EBNA-1) Peptide pool is a lyophilised mixture of 158 peptides from Epstein-Barr nuclear antigen 1 (EBNA-1) of Epstein-Barr virus (EBV; strain B95-8). EBNA-1 plays a critical role in the stable latent infection by EBV and may contribute to the survival of EBV-infected cells through its interaction with ubiquitin carboxyl-terminal hydrolase 7 (USP7). The pool consists of 15-mer peptides with 11-amino-acid overlaps that cover amino acids 1 to 641 on EBNA-1.

Stimulating T cells with Candida (MP65) peptide pool releases downstream cytokines and upregulates activation markers, enabling antigen-specific T cells to be detected or isolated for analysis. Candida peptide pool is a lyophilised mixture of 92 peptides from the mannoprotein MP65 of Candida albicans (yeast), and consists of 15-mer peptides with 11-amino-acid overlaps that cover amino acids 1 to 379 on MP65. MP65 contributes to cell wall integrity and epithelia adherence (Sandini et al.), and is a potent T cell immunogen (Gomez et al.). Viral peptide pools are useful for a broad range of applications, including vaccine development, immunological research, and diagnostic assay development.

The principal physiological regulator of erythropoiesis, Erythropoietin (EPO) is a glycoprotein growth factor that is produced primarily in the kidney in response to hypoxia or anemia. EPO promotes erythropoiesis by binding to a homodimeric cell surface receptor that activates JAK2/STAT5, PI3K/AKT, and MAPK pathways, and stimulates the proliferation and differentiation of erythroid progenitor cells (Jelkmann. Transfus Med Hemother, 2013; Kuhrt and Wojchowski. Blood, 2015).

Noggin binds to and antagonizes bone morphogenetic protein (BMP) ligands of the transforming growth factor beta (TGF-β) family. Noggin supports maintenance of undifferentiated human embryonic stem cells in vitro, and can be used to prevent spontaneous differentiation in the short term (Chaturvedi et al.). Noggin is essential for development of structures derived from ectoderm embryonic somite, skeletal patterning, and neurogenesis in vivo. It also influences chondrogenesis, osteogenesis, and joint formation (Krause et al.), and promotes dopaminergic differentiation of embryonic stem cells and subsequent survival of dopamine neurons (Chiba et al.).

Epidermal growth factor (EGF) is characterized by high affinity binding to various EGF receptors (EGFRs) and the production of mitogenic responses (Carpenter and Cohen). EGF promotes EGFR dimerization, resulting in activation of downstream pathways including PI3K, ERK1/2, JAK/STAT, β-catenin, and calcium signaling. EGF is secreted by the gut-associated salivary and Brunner’s glands, is found in a variety of body fluids, and stimulates cell proliferation and differentiation in rodent and neonatal human intestine (Wright et al.). Central nervous system stem cells also proliferate in response to the EGF stimulus (Reynolds and Weiss).

SARS-CoV-2 Recombinant Spike Protein, aa16-685 is expressed in HEK293 cells and is one of four structural proteins encoded by the SARS-CoV-2 genome. The Spike Protein plays a key role in attachment to host cells, allowing invasion through clathrin-mediated endocytosis. The Spike Protein can be cleaved by host cell proteases after aa685 to yield the N-terminal S1 subunit and C-terminal S2 region. The S1 subunit is responsible for interacting with the host cell receptor (angiotensin-converting enzyme II) through a receptor-binding domain that is highly conserved with SARS-CoV. The S1 subunit has two conformations: a ‘down’ conformation in which the receptor is inaccessible, and an ‘up’ conformation in which the receptor is accessible. These conformational changes are key for monoclonal antibody drugs and vaccine development. SARS-CoV-2 Recombinant Spike Protein contains a polyhistidine tag at the amino terminus; it also contains a FLAG tag at the carboxy terminus.

Vascular endothelial growth factor (VEGF-121) is a naturally-occurring VEGF-A splice variant involved in embryonic vasculogenesis and angiogenesis. VEGF binds to VEGFR-1 and VEGFR-2, and activates Raf/MEK/ERK and PI3K/AKT pathways. VEGF-121 is released as a freely diffusible protein by a variety of normal and transformed cells. It plays an important role in neurogenesis both in vitro and in vivo (Storkebaum et al.). It has neurotrophic effects on neurons of the central nervous system and promotes growth and survival of dopaminergic neurons and astrocytes. VEGF also promotes growth and survival of vascular endothelial cells, monocyte chemotaxis, and colony formation by granulocyte-macrophage progenitor cells (Ferrara et al.).

Amphiregulin is a member of the epidermal growth factor (EGF) family. It binds to several receptors including EGFR/ErbB1, HER2/ErbB2, HER3/ErbB3, and HER4/ErbB4, which activates Ras/Raf/MAPK and PI3K/AKT pathways. This results in cell proliferation, apoptosis resistance, and invasive behaviour (Normanno et al.). The expression of amphiregulin is induced by tissue injury and inflammation. Amphiregulin promotes mammary development, trophoblast growth, lung and kidney branching morphogenesis, and keratinocyte proliferation. It stimulates the growth of most cell types, including normal and transformed mammary epithelial cells, and malignant cells of the colon, prostate, cervix, and pancreas (Berasain and Avila).

Insulin-like growth factor 1 (IGF-I) is a polypeptide that belongs to the family of insulin-like growth factors that are similar in molecular structure to proinsulin. IGF-I binds to the IGF-I receptor and is a potent activator of the PI3K/AKT pathway and also activates ERK1/2 signaling. IGF-I is required for embryonic development, and it is produced mainly in the liver in response to a hepatocyte growth hormone. In the absence of insulin, IGF-I is necessary for the maintenance of human pluripotent stem cells (Wang et al.). Together with IL-3, IGF-I stimulates differentiation and proliferation of myeloid cells and has been shown to regulate lymphopoiesis by stimulating proliferation and differentiation of T and B cells in lymphoid organs (Heemskerk et al.).
