  • Immunohistochemistry Services

  • Work with LifeSpan to design a custom immunohistochemistry to address your specific biological question. Outsource the entire localization process without having to worry about finding and characterizing target specific antibodies, sourcing and validating difficult-to-find tissues, and having the ability to interpret the resulting immunostaining in relation to complex human pathologies.

  • TCR Screening Services

  • Test your therapeutic antibodies in immunohistochemistry against a broad panel of normal frozen human tissue types in order to determine potential unintended binding. Our non-GLP TCR services are designed on the FDA recommendation outlined in their "Points to Consider in the Manufacture and Testing of Monoclonal Antibody Products for Human Use".

Description: Smoothened (SMO) is a GPCR-like receptor which, with Patched, mediates hedgehog signaling to regulate gene expression through the Gli transcription factors. SANT 1 is a potent inhibitor of hedgehog signaling that acts by directly antagonizing SMO (IC50 = 20 nM). It counteracts SMO activation by the SMO agonist SAG but only partially competes with SAG binding to SMO. SANT 1 targets inactive SMO while it is in the cytoplasm, before it relocates to the primary cilium and is activated. Through antagonism of SMO, SANT 1 represses Gli-mediated transcription in a variety of cell types. H107_ChemicalStructureImage.png

Usage Information

SANT 1 is supplied as a crystalline solid. A stock solution may be made by dissolving the SANT 1 in the solvent of choice. SANT 1 is soluble in organic solvents such as ethanol, DMSO, and dimethyl formamide, which should be purged with an inert gas. The solubility of SANT 1 in these solvents is approximately 5, 3, and 10 mg/ml, respectively. SANT 1 is sparingly soluble in aqueous solutions. To enhance aqueous solubility, dilute the organic solvent solution into aqueous buffers or isotonic saline. If performing biological experiments, ensure the residual amount of organic solvent is insignificant, since organic solvents may have physiological effects at low concentrations. We do not recommend storing the aqueous solution for more than one day.
