Glial cell line-derived neurotrophic factor (GDNF) is a neurotrophic factor and a member of the tumor growth factor (TGF)-beta superfamily. The GDNF family of growth factors also includes neurturin, persephin, and artemin, which have seven conserved cysteine residues called cysteine-knot (Treanor et al.). GDNF family ligands signal through binding to specific GDNF-family receptor-α (GFRα) co-receptors and activate the RET receptor tyrosine kinase (Durbec et al.). Four different forms of GFRα co-receptors have been characterized (GFRα 1-4) out of which GDNF binds specifically to GFRα1 prior to forming a complex with RET (Airaksinen and Saarma). GDNF is known to promote survival and morphological differentiation of midbrain dopaminergic neurons in both in vivo and in vitro studies and increase their high-affinity dopamine uptake (Granholm et al.; Lin et al.). GDNF has also been shown to have restorative effects on dying dopaminergic neurons in response to degenerative toxins (Aoi et al.). GDNF, together with Human Recombinant BDNF (brain-derived neurotrophic factor; Catalog #78005), BrainPhys™ Neuronal Medium (Catalog #05790), and other supplements, can be used to differentiate human pluripotent stem cell (hPSC)-derived neural progenitor cells into neurons (Bardy et al.). This product is animal component-free.

Stimulating T cells with SARS-CoV-2 (Spike Protein) Omicron BA.4/BA.5 Peptide pool releases downstream cytokines and upregulates activation markers, enabling antigen-specific T cells to be detected or isolated for analysis. This pool is provided as two lyophilised mixtures (subpools) from the spike glycoprotein of SARS-CoV-2 Omicron BA.4/BA.5 subvariant. The subpools contain 158 and 157 peptides, respectively, for a total of 315 peptides, and they consist of 15-mer peptides with 11-amino-acid overlaps that cover amino acids 1 to 1270 on the spike protein. Through interactions with the angiotensin-converting enzyme 2 (ACE2) receptor, the spike protein enables the virus to attach to the cell membrane, and plays a critical role in viral entry (Hoffmann et al.; Walls et al.). Viral peptide pools are useful for a broad range of applications, including vaccine development, immunological research, and diagnostic assay development.

Indian hedgehog (IHH) is one of three proteins in the hedgehog family which includes sonic hedgehog and desert hedgehog. Hedgehog proteins are important signaling molecules, acting through patched and smoothened receptors. During embryonic development, they are expressed in the fetal lung, gut, stomach, liver, kidney, and pancreas. IHH is strongly expressed in cartilage and regions of developing bone, and its signaling regulates growth and differentiation of bone tissue (Marigo et al.; Valentini et al.; St-Jacques et al.). IHH is also involved in yolk sac vasculogenesis, indicating a role in the differentiation of epiblast cells into endothelial and red blood cells (Byrd et al.). IHH induces the expression of parathyroid hormone-related peptide (PTHrP), which negatively regulates IHH during chondrocyte differentiation and proliferation (Vortkamp et al.).

Tumor necrosis factor-beta (TNF-β), also known as lymphotoxin-alpha, is a member of the TNF family. It is a pro-inflammatory cytokine that activates NF-kB, MAPK, and PI3K/AKT pathways upon binding to TNF receptors 1 and 2. It is produced mainly by T cells, though other cells can express TNF-β at lower levels (Chu). TNF-β is involved in autoimmune disorders, lymph node development, and mediating the inflammatory demyelination process (Seleznik et al.; McCarthy et al.).

The platelet-derived growth factor (PDGF) family has five heparin-binding members that assemble into four homodimers (PDGF-AA, PDGF-BB, PDGF-CC, and PDGF-DD) and one heterodimer (PDGF-AB; Fretto et al.; Li and Eriksson). PDGF signals through the receptor tyrosine kinases PDGFRα and PDGFRβ. It has been shown that PDGF-induced migration involves signaling pathways involving MEK/ERK, EGFR, Src, and PI3K/AKT (Kim et al.). PDGF is a potent mitogen for cells of mesenchymal origin, such as fibroblasts, glial cells, and vascular smooth muscle cells. PDGF has been implicated in pathogenesis of atherosclerosis, glomerulonephritis, cancer, and in the contraction of vascular smooth muscle cells of rat aortic tissues (Fretto et al.; Sachinidis et al.). PDGF-BB is secreted by osteoblasts to induce mesenchymal stem cell migration and angiogenesis. It has also been shown that PDGF-BB is secreted by preosteoclasts during bone modeling and remodeling to induce angiogenesis and thus proper osteogenesis (Xie et al.).

Myostatin is a member of transforming growth factor beta (TGF-β) superfamily that signals by binding to activin type II receptor, resulting in the recruitment of either ALK3 or ALK4 coreceptor, and activation of SMAD2/3 (Kondás et al.). It is released by myocytes and inhibits muscle growth and ability to regenerate (Lee and Lee). Myostatin appears to affect the lipid catabolic metabolism of adipocytes and inhibits preadipocyte differentiation, as demonstrated in the 3T3-L1 cell line (Li et al.).

Stimulating T cells with CMV (IE-1) peptide pool releases downstream cytokines and upregulates activation markers, enabling antigen-specific T cells to be detected or isolated for analysis. CMV (IE-1) peptide pool is a lyophilised mixture of 120 peptides from the immediate early protein IE1 (IE1) of human cytomegalovirus (CMV; strain AD169), and consists of 15-mer peptides with 11-amino-acid overlaps that cover amino acids 1 to 491 on IE1. CMV IE1 is a transcriptional transactivator and autoregulator (Cherrington and Mocarski). Studies show that IE1 promotes viral transcription by antagonizing histone deacetylation (Nevels et al.) and, along with IE2, may contribute to the survival of CMV-infected cells by blocking tumor necrosis factor alpha (TNF-α)-induced apoptosis (Zhu et al.). Viral peptide pools are useful for a broad range of applications, including vaccine development, immunological research, and diagnostic assay development.

Human (Actin) peptide pool is a lyophilised mixture of 92 peptides from human actin, alpha skeletal muscle, and consists of 15-mer peptides with 11-amino-acid overlaps that cover amino acids 1 to 377 on actin. It is frequently used as a negative control. Actin, alpha skeletal muscle, is part of the highly conserved actin protein family and is the predominant isoform found in adult skeletal muscle (Laing et al.). Peptide pools are useful for a broad range of applications, including vaccine development, immunological research, and diagnostic assay development.

Interleukin 10 (IL-10) is the founding member of the IL-10 family of class II cytokines. All of the IL-10 cytokine family members have a four-helix bundle consisting of α-helical folds. Upon binding to its receptor, IL-10 activates signaling through JAK1 and STAT3. It is produced by dendritic cells, macrophages, and CD4+ T cells, as well as mast cells, NK cells, neutrophils, and B cells, under specific stimulating conditions (Saraiva and O'Garra). IL-10 can inhibit the expression of pro-inflammatory cytokines and promote healing processes, and is important for the function of regulatory T cells. IL-10 also enhances B cell proliferation, immunoglobulin secretion, and class II MHC expression, while IL-10 produced by macrophages inhibits activation of neighboring macrophages, thus allowing a level of self-regulation (Ouyang et al.).
