SARS-CoV-2 Spike Protein S1 (RBD) (rec.) (His) (P.1 Variant, Gamma) Reference: AG-40B-0207 SARS-CoV-2 shares 79.5% sequence identity with SARS-CoV and is 96.2% identical at the genome level to the bat coronavirus BatCoV RaTG133, suggesting it had originated in bats. The coronaviral genome encodes four major structural proteins: the Spike (S) protein, Nucleocapsid (N) protein, Membrane/Matrix (M) protein and the Envelope (E) protein. The SARS Envelope (E) protein contains a short palindromic transmembrane helical hairpin that seems to deform lipid bilayers, which may explain its role in viral budding and virion envelope morphogenesis. The SARS Membrane/Matrix (M) protein is one of the major structural viral proteins. It is an integral membrane protein involved in the budding of the viral particles and interacts with SARS Spike (S) protein and the Nucleocapsid (N) protein. The N protein contains two domains, both of them bind the virus RNA genome via different mechanisms. The CoV Spike (S) protein assembles as trimer and plays the most important role in viral attachment, fusion and entry. It is composed of a short intracellular tail, a transmembrane anchor and a large ectodomain that consists of a receptor binding S1 subunit (RBD domain) and a membrane-fusing S2 subunit. The S1 subunit contains a receptor binding domain (RBD), which binds to the cell surface receptor angiotensin-converting enzyme 2 (ACE2) present at the surface of epithelial cells. Recently, a new variant of SARS-CoV-2, called P.1 (Gamma) was detected in Brazil. This variant carries three mutations in the RBD at the positions 417, 484 and 501 (K417T, E484K, N501Y). The P.1 or Brazilian variant is a form of the SARS-CoV-2 coronavirus that appears to have evolved in Brazil and might have contributed to a surge in cases in the northern city of Manaus. The SARS-CoV-2 Spike Protein S1 (RBD) (rec.) (His) (P.1 Variant, Gamma) can be used as antigen in Serological ELISA Kits to detect anti-SARS-CoV-2 Spike (RBD) antibodies in serum or plasma.

Fc (human):FNDC4 (rec.) Reference: AG-40B-0213 Irisin is a recently described exercise-induced hormone secreted by skeletal muscle in mice and humans. Irisin activates beige fat cells (beige cells have a gene expression pattern distinct from either white or brown fat and are preferentially sensitive to the polypeptide hormone irisin). Irisin is cleaved from the type I membrane protein FNDC5 and improves systemic metabolism by increasing energy expenditure. FNDC4 is an ortholog of FNDC5 with 50% identity and 86% similarity compared to Irisin. FNDC4 as well as FNDC5 are extremely well conserved between species. The human FNDC4 gene is highly enriched in liver, brain tissue and adipocytes. FNDC4 is a factor with direct therapeutic potential in inflammatory bowel disease and possibly other inflammatory diseases. Recently, a new role of FNDC4 as a hepatokine has been published. Liver primarily controls the circulating levels of FNDC4 showing tight correlation with insulin sensitivity. In addition, a new orphan adhesion G protein-coupled receptor 116 (GPR116) has been identified as a receptor of FNDC4 in white adipose tissue (WAT), thereby establishing an endocrine FNDC4-GPR116 axis in the control of systemic glucose homeostasis. Moreover, the FNDC4-GPR116 axis is impaired in diabetic patients and therapeutic injections of recombinant Fc-FNDC4 into pre-diabetic mice corrected pre-diabetic hyperglycemia.
CD123 [IL-3Ralpha] (human)-muIg Fusion Protein (Biotin) Reference: ANC-545-030 Human CD123 (Interleukin-3 Receptor alpha) is a 70kDa type I transmembrane molecule, and is the low affinity receptor for the cytokine IL-3, which can stimulate proliferation or differentiation. When paired in a heterodimer with CD131 (IL-3Rbeta), it binds IL-3 with much higher affinity. CD123 is found on myeloid precusors, stem cells, a subset of T cells, some B cells, megakaryocytes, basophils, monocytes and epithelial cells. CD123 is present at high levels on many hematologic malignancies, and antibodies and CAR T cells against CD123 have been used successfully to combat acute myeloid leukemia (AML).
CD304 (human)-muIg Fusion Protein Reference: ANC-557-020 Human CD304 (neuropilin, NRP, NP1, BDCA-4) is a 140 kD type I glycoprotein expressed by a variety of tissue types,including Treg, follicular TH, neurons, dendritic cells and endothelial cells. Its ligands include VEGF165 and Semaphorin family members. It is a reliable marker for human BCP-ALL. Soluble CD304 has been used to slow progression of murine AML.

Isthmin-1 (human) (rec.) (His) Reference: AG-40B-0214 Isthmin-1 (ISM1) was first identified as a gene expressed in the Xenopus midbrain hind brain organizer called isthmus, with a proposed role during early brain development. Isthmin-1 encodes a predicted ~50-kDa protein containing a signal peptide, a thrombospondin domain and an adhesion-associated domain. Isthmin-1 is important for embryonic and postnatal development. Growing evidence has shown that aberrant expression of Isthmin-1 can also affect the biological behavior of cancer. The Ism1 gene is conserved in mice and humans. A recent study showed that Ism1 is an adipokine that induces glucose uptake in human and mouse adipocytes. Ism1 is secreted by mature adipocytes and triggers a signaling cascade similar to that of insulin, regulating glucose uptake while suppressing lipid accumulation. Recombinant Isthmin-1 or overexpression of Ism1 causes a robust increase in GLUT4-dependent glucose uptake in cultured primary murine and immortalized human adipocytes as well as in primary human muscle cells and prevents insulin resistance and hepatic steatosis in a diet-induced obesity mouse model. Ablation of Isthmin-1 causes glucose intolerance and impaired insulin-stimulated adipocyte glucose uptake. Isthmin-1 suppresses de novo lipogenesis and increases protein synthesis in hepatocytes whereas Isthmin-1 knockdown in adipocytes reduces glucose uptake and insulin-dependent phosphorylation of protein kinase AKT at serine residue 473 (p-AKTSer473). Isthmin-1 signaling is dependent on PI3K and shares downstream phosphorylation targets with insulin signaling, such as p-AKTSer473, p-AKTThr308, p-ERK1/2Thr202/Tyr204 and p-S6Ser235/236. Isthmin-1 does not seem to act through the insulin receptor or the insulin-like growth factor 1 receptor; it is most likely to signal through another, yet to be identified, receptor tyrosine kinase.

TAPBPL (mouse):Fc (human) (rec.) Reference: AG-40B-0216 T cells play critical roles in the adaptive immune system, protecting the human body against cancer, bacterial, viral, fungal, and parasitic infections. T cell immune response is tightly controlled by immune checkpoint proteins that negatively or positively regulate T cell response. Among the immune checkpoint proteins, the B7 family plays a key role in controlling immune responses and belongs to the immunoglobulin (Ig) superfamily. A number of B7 family ligands have been identified, such as B7-1 (CD80), B7-2 (CD86), PD-L1 (B7-H1), PD-L2 (B7-DC), B7-H2 [inducible T cell co-stimulator ligand (ICOS)], B7-H3, B7-H4 (B7x, B7S1), B7-H5 (VISTA) and B7- H6. Because of the potential clinical applications of immune checkpoint proteins, there has been intense interest in identifying additional T-cell regulators. Recently, new antigen processing (TAP) binding protein-like (TAPBPL)/TAP binding protein-related (TAPBPR) molecule has been shown to share significant sequence similarity with some known B7 family members. TAPBPL protein is expressed on the surface of T cells, on antigen-presenting cells (APCs) including resting B cells, monocytes, macrophages, and DCs, as well as on some cancer cells including leukemia cells. TAPBPL behaves like other immune checkpoint proteins such as B7-H5 / VISTA or PD-L1 with a soluble recombinant version TAPBPL-Fc fusion protein that inhibits the proliferation and activation of CD4 and CD8 T cells in vitro and ameliorates autoimmune disease EAE in vivo. In contrast, treatment with anti-TAPBPL blocking antibody enhances antitumor immunity and inhibits tumor growth in vivo. Therefore, TAPBPL contains typical features of B7 family members, suggesting that it is a B7 family member or a B7 family-related molecule.
