  • 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 cell surface receptor that, with Patched, mediates hedgehog signaling to regulate gene expression through the Gli transcription factors. GSA 10 is a quinolinecarboxamide derivative that acts as an agonist of SMO. By acting at SMO, GSA 10 has been shown to promote the differentiation of multipotent mesenchymal progenitor cells into osteoblasts (EC50 = 1.2 µM). Most notably, GSA 10 does not recognize the classic cyclopamine binding site as do other SMO agonists and as such has been used to characterize a novel SMO active site.

Usage Information

GSA 10 is supplied as a crystalline solid. A stock solution may be made by dissolving the GSA 10 in the solvent of choice. GSA 10 is soluble in dimethyl formamide at a concentration of approximately 1 mg/ml. GSA 10 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.
