Mouse Recombinant IL-5
Supplier: STEMCELL Technologies
Interleukin 5 (IL-5) is a member of the short-chain 4-α-helical bundle subset of hematopoietic cytokines. It binds to the specific α receptor, which in turn recruits the common β receptor that initiates signaling via JAK/STAT and MAPK pathways. IL-5 is produced by Th2 cells, eosinophils, activated mast cells, and ILC2 cells. IL-5 affects the differentiation, activation, and survival of eosinophils, thus playing an important role in allergic inflammation, asthma, and parasite immunity. Stimulation of eosinophils with IL-5 leads to their activation, upregulation of CD11b expression, and inhibition of apoptosis (Shearer).

Human Recombinant Osteopontin, His tag
Supplier: STEMCELL Technologies
A member of the SIBLING family of glycoproteins (Rangaswami et al.), Osteopontin (OPN) functions as T-helper 1 cytokine, and plays an important role in cell signaling, migration, and activation (Weber et al., 2002). Osteopontin has been shown to regulate inflammation both in vitro and in vivo (Agnholt et al.; Kiefer et al.), and has been implicated in the pathophysiology of numerous cancers, including prostate (Thalmann et al.), lung (Chambers et al.), ovarian (Kim et al.), and breast etiologies (Weber et al., 2015). In humans, OPN is initially secreted as a 317 amino acid protein which is subject to tissue-specific post-translational modifications by glycosylation, phosphorylation, and transglutamination (Kazanecki et al.; Sodek et al.). This protein product contains a His-residue tag at the amino end of the polypeptide chain. For consistency and reproducibility across your applications, Osteopontin from STEMCELL comes lyophilised with ≥92% purity, and endotoxin levels are verified to be ≤1,0 EU/μg protein.

HPV16 (E6) Peptide Pool
Supplier: STEMCELL Technologies
Stimulating T cells with HPV16 (E6) Peptide Pool releases downstream cytokines and upregulates activation markers, enabling antigen-specific T cells to be detected or isolated for analysis. HPV16 (E6) Peptide Pool is a lyophilised mixture of 37 peptides from the E6 protein of human papillomavirus type 16 (HPV16). The pool consists of 15-mer peptides with 11-amino-acid overlaps that cover amino acids 1 to 158 on protein E6. E6 binds to the tumor suppressor protein p53 and stimulates its degradation (Scheffner et al.; Werness et al. ), which is thought to cause an increase in spontaneous mutagenesis in host cells (Havre et al.). E6 together with E7 demonstrated the ability to immortalize human keratinocytes in vitro, which likely has significance for HPVs oncogenic potential (Hawley-Nelson et al.). Viral peptide pools are useful for a broad range of applications, including vaccine development, immunological research, and diagnostic assay development.

Human Recombinant Sclerostin, His Tag
Supplier: STEMCELL Technologies
Use sclerostin to alter bone remodeling homeostasis, where it inhibits bone formation in vivo and in vitro, likely through Wnt/β-catenin signaling cascades (Ellies et al.; Lin et al.). Sclerostin is a member of the cerberus/DAN family of glycoproteins whose members share a C-terminal cysteine-knot-like (CTCK) domain. Highly expressed in bone and cartilage, as well as in kidney, and liver tissues (Weivoda et al.), this osteoclast-derived BMP antagonist binds BMP6 and BMP7 with high affinity, and binds BMP2 and BMP4 with a lower affinity (Kusu et al.). Mutations in the SOST gene have been associated with sclerosteosis (Brunkow et al.), van Buchem disease (Staehling-Hampton et al.), and bone dysplasia disorders, characterized by increased bone density. This protein product contains a His-residue tag at the carboxyl end of the polypeptide chain. For consistency and reproducibility across your applications, sclerostin from STEMCELL comes lyophilised with ≥87% purity, and endotoxin levels are verified to be ≤1.0 EU/μg protein.

Human Recombinant 15-PGDH, His tag
Supplier: STEMCELL Technologies
Modulate prostaglandin metabolism with 15-hydroxyprostaglandin dehydrogenase (15-PGDH). 15-PGDH catalyses the reversible oxidation of the 15-hydroxyl group in prostaglandins, resulting in inactivated metabolites (Ensor and Tai), it can act on a variety of prostaglandins as substrates in a NAD+ dependent manner (Cho et al.). As prostaglandins can have a range of effects on cellular processes, 15-PGDH is of considerable importance in drug development. In vitro and in vivo studies suggest 15-PGDH has tumor suppressive activity and is downregulated in certain cancers (Na et al.).15-PGDH belongs to the short-chain dehydrogenases/reductases (SDR) family; its primary structure indicates 20% homology with other SDRs, with some conserved amino acid residues (Krook et al.). This protein contains a His-residue tag at the carboxyl end of the polypeptide chain. For consistency and reproducibility across your applications, apo M from STEMCELL comes lyophilised with ≥89% purity.

Human Recombinant Fetuin B, His tag
Supplier: STEMCELL Technologies
Fetuin B is thought to have functions in female fertility, metabolism, and liver disease. A protease inhibitor belonging to the fetuin family of proteins, within the cystatin superfamily, fetuin b’s structure includes two cystatin domains (CY1 and CY2) connected by a linker, with a CPDCP-trunk and a C-terminal region (CTR) (Cuppari et al.). This plasma protein originates in the liver (Denecke et al.) and acts to inhibit the activity of ovastacin, a metalloprotease that causes the zona pellucida to harden, leading to female infertility (Karmilin et al.). Fetuin B has also been reported to increase apoptosis, and inhibit migration and invasion of prostate cancer cells, in in vitro and in vivo settings (Zhan et al.). Elevated serum fetuin B has been linked to non-alcoholic fatty liver disease (NAFLD) (Zhu et al.). This protein contains a His-residue tag at the carboxyl end of the polypeptide chain. For consistency and reproducibility across your applications, apolipoprotein H from STEMCELL comes lyophilised with ≥92% purity, and is verified by LAL analysis to ensure endotoxin levels are ≤1,0 EU/μg protein.
