  • 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: G protein-coupled estrogen receptor (GPER), or GPR30, specifically binds natural and man-made estrogens. It is thought to be involved in estrogen-sensitive cancers. GPER knockout mice are fertile, although they exhibit thymic atrophy, impaired glucose tolerance, and altered bone growth. G-15 is a cell-permeable non-steroidal antagonist of GPER (Ki = 20 nM). It displays low affinity cross-reactivity with the classical estrogen receptor (ER), ER alpha, so that at doses greater than 1 µM it is capable of mediating limited ER-dependent transcriptional activity. G-15 antagonizes the anti-depressive effects of estrogen in vivo. H105_ChemicalStructureImage.png

Usage Information

G-15 is supplied as a crystalline solid. A stock solution may be made by dissolving the G-15 in the solvent of choice. G-15 is soluble in organic solvents such as ethanol, DMSO, and dimethyl formamide (DMF), which should be purged with an inert gas. The solubility of G-15 in these solvents is approximately 1, 20, and 30 mg/ml, respectively. G-15 is sparingly soluble in aqueous buffers. For maximum solubility in aqueous buffers, G-15 should first be dissolved in DMF and then diluted with the aqueous buffer of choice. G-15 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.
