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: XCT790 is an inverse agonist of estrogen-related receptor alpha (ERR alpha ; IC50 = ~300-500 nM). It demonstrates 90-100% inhibition of ERR alpha constitutive activity and has no significant activity at related nuclear receptors at 10 µM. XCT790 associates with the ligand-binding domain of ERR alpha and blocks ERR alpha /PGC-1 alpha -dependent signaling, suppressing the expression of monoamine oxidases A and B. XCT790 induces proteasomal degradation of ERR alpha and potentiates the degradation of the estrogen receptor ER alpha by fulvestrant .
XCT790 is supplied as a crystalline solid. A stock solution may be made by dissolving the XCT790 in the solvent of choice. XCT790 is soluble in organic solvents such as DMSO and dimethyl formamide (DMF), which should be purged with an inert gas. The solubility of XCT790 in these solvents is approximately 3 and 12 mg/ml, respectively. XCT790 is sparingly soluble in aqueous buffers. For maximum solubility in aqueous buffers, XCT790 should first be dissolved in DMF and then diluted with the aqueous buffer of choice. XCT790 has a solubility of approximately 0.03 mg/ml in a 1:30 solution of DMF:PBS (pH 7.2) using this method. We do not recommend storing the aqueous solution for more than one day.
