Protirelin – Thyrotropin-releasing hormone (TRH) (CAS: 24305-27-9) Thyrotropin-releasing hormone (TRH) Thyrotropin-releasing hormone (TRH) is a tripeptide hypothalamic regulatory hormone that regulates the release of thyroid-stimulating hormone (TSH), as well as prolactin (for breasts growth and milk production during and after pregnancy). To obtain thyrotropin-releasing hormones, 6 pro-TRH peptides have first to be obtained from the larger preproTRH precursor (UniProt: P20396). These octapeptides are then cleaved between Arginine/Glutamine and Glutamine/Lysine residues to release 6 Gln-His-Pro-Gly peptides that will be enzymatically converted in pGln-His-Pro-NH2 peptides (pGln representing pyroglutamine). After TRH maturation (1) in neurons located in the pituitary gland, the hormone will be transported along axons (2) to reach the hypophyseal portal system via exocytosis (3). Once the thyrotrophs reached, thyrotropin-releasing hormone binds TRH-receptor (4) to enable TSH syn

Haemagglutinin (HA) peptide YPYDVPDYA – HA Tag SB-PEPTIDE offers Human influenza hemagglutinin (HA) tag YPYDVPDYA, which is a well characterized 9 amino acids synthetic peptide deriving from an epitope of the original influenza hemagglutinin protein. Haemagglutinin surface fusion glycoprotein for viral entry Haemagglutinin (HA) (UniProt : P03437) is an envelope protein present in the viral membrane of influenza viruses. HA forms a trimer containing structurally distinct regions and an intact HA0 polypeptide composed of two subunits, called HA1 and HA2, connected by one disulfide bridge. Haemagglutinin (HA) 3D structure. HA tag SB-PEPTIDE_CAS: 92000-76-5 To initiate their fusion with their cellular hosts, influenza viruses first bind to sialic acids at the surface of respiratory epithelial cells. Following this interaction, they will enter the cell via endocytosis. Endosomal uptake of influenza virus - HA tag SB-PEPTIDE_CAS: 92000-76-5 Due to proton pumps on t

Huwentoxin IV (HwTx-IV) is a neurotoxin that was originally isolated from Haplopelma schmidti (Chinese bird spider). This lethal neurotoxin acts selectively on tetrodotoxin-sensitive (TTX-S) voltage-gated sodium channels, with an IC50 of 30 nM in rat DRG neurons. It preferentially inhibits neuronal voltage-gated sodium channel subtype hNav1.7 (SCN9A, IC50 is 26 nM), rNav1.2 (SCN2A, IC50 is 150 nM), and rNav1.3 (SCN3A, IC50 is 338 nM), compared with muscle subtypes rNav1.4 (SCN4A) and hNav1.5 (SCN5A) (IC50 is > 10 µM). Huwentoxin IV inhibits the activation of sodium channels by trapping the voltage sensor of domain II of the site 4 in the inward, closed configuration. Cy5-Huwentoxin IV is a fluorescently tagged version of Huwentoxin IV.

Cy5-ProTx-II is a fluorescently labeled ProTx-II, a famous Nav1.7 blocker. The wild type ProTx-II blocks Nav1.7 with an IC50 value of around 300 pM, Nav1.2, Nav1.5 and Nav1.6 with IC50 values of 41 nM, 79 nM and 26 nM respectively. The Cy5-ProTx-II version developed by Smartox has potent Nav1.7 blocking activity. It was shown to fully block Nav1.7 at 100 nM concentration.

Vascular endothelial growth factor (VEGF) is a potent angiogenic factor and was first described as an essential growth factor for vascular endothelial cells. VEGF is up-regulated in many tumors and its contribution to tumor angiogenesis is well defined.
