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: GPR120 (free fatty acid receptor 4; FFAR4) is a G protein-coupled receptor (GPCR) expressed in intestine, adipocytes, and pro-inflammatory macrophages that is activated by long chain free fatty acids. ω-3 Fatty acids, such as docosahexaenoic acid and eicosapentaenoic acid, initiate GPR120 signaling resulting in inhibition of toll-like receptor and TNF- alpha inflammatory signaling pathways in a beta -arrestin2/TAB1 dependent manner. TUG-891 is a potent and selective agonist of GPR120 with pEC50 values of 7.36 and 7.77 for human and mouse GPR120, respectively. It activates GPR40 (FFAR1) with a pEC50 value of 4.19 and shows no activity at GPR41 (FFAR3) or GPR43 (FFAR2).
TUG-891 is supplied as a crystalline solid. A stock solution may be made by dissolving the TUG-891 in the solvent of choice. TUG-891 is soluble in organic solvents such as ethanol, DMSO, and dimethyl formamide (DMF), which should be purged with an inert gas. The solubility of TUG-891 in ethanol and DMF is approximately 1 mg/ml and approximately 10 mg/ml in DMSO. TUG-891 is sparingly soluble in aqueous buffers. For maximum solubility in aqueous buffers, TUG-891 should first be dissolved in DMSO and then diluted with the aqueous buffer of choice. TUG-891 has a solubility of approximately 0.1 mg/ml in a 1:5 solution of DMSO:PBS (pH 7.2) using this method. We do not recommend storing the aqueous solution for more than one day.
