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-36 is a cell-permeable non-steroidal antagonist of GPER, inhibiting activation by either 17 beta -estradiol or the GPER-selective agonist G-1 (IC50 = 112 and 165 nM, respectively). It has no detectable binding activity to either ER alpha or ER beta . G-36 blocks the activation of PI3K or calcium mobilization triggered by estrogen through GPER and it suppresses ERK activation by estrogen or G-1 but not by EGF. G-36 can be used in combination with GPER-selective agonists, like G-1, to distinguish the roles of GPER from those of ER alpha and ER beta in complex biological systems.
G-36 is supplied as a crystalline solid. A stock solution may be made by dissolving the G-36 in the solvent of choice. G-36 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-36 in these solvents is approximately 1, 20, and 30 mg/ml, respectively. G-36 is sparingly soluble in aqueous buffers. For maximum solubility in aqueous buffers, G-36 should first be dissolved in DMF and then diluted with the aqueous buffer of choice. G-36 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.
