  • 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: The G protein-coupled receptors GPR109A and GPR109B are recognized to be receptors for hydroxy-carboxylic acid (HCA) metabolites, are abundant in adipocytes, and are relevant to atherosclerosis and dyslipidemia. IPBT-5CA is a selective agonist of GPR109B (HCA3; EC50 = 400 nM). It displays no activity at GPR109A (HCA2). IBC-293 inhibits forskolin-stimulated cAMP release in Chinese hamster ovary cells stably expressing GPR109B (EC50 = 54 nM) but not in cells expressing GPR109A. This is accompanied by a rapid and transient increase in intracellular calcium and activation of ERK1/2 through a pertussis toxin-sensitive Gi signaling pathway. H115_ChemicalStructureImage.png

Usage Information

IPBT-5CA is supplied as a crystalline solid. A stock solution may be made by dissolving the IPBT-5CA in the solvent of choice. IPBT-5CA is soluble in organic solvents such as ethanol, DMSO, and dimethyl formamide (DMF), which should be purged with an inert gas. The solubility of IPBT-5CA in these solvents is approximately 5, 25, and 16 mg/ml, respectively. IPBT-5CA is sparingly soluble in aqueous buffers. For maximum solubility in aqueous buffers, IPBT-5CA should first be dissolved in DMF and then diluted with the aqueous buffer of choice. IPBT-5CA has a solubility of approximately 0.5 mg/ml in a 1:1 solution of DMF:PBS (pH 7.2) using this method. We do not recommend storing the aqueous solution for more than one day.
