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: NESS 0327 is an extremely potent cannabinoid (CB) receptor antagonist with high selectivity for the CB1 receptor compared to the CB2 receptor with Ki values of 0.35 pM and 21 nM, respectively. It is a much more potent antagonist and more selective for the CB1 receptor compared to SR 141716A (rimonabant). At nM concentrations NESS 0327 competitively inhibits the binding of the synthetic CB agonist WIN 55,212-2 in isolated rat cerebella membranes and murine vas deferens. Unlike SR 141716A, NESS 0327 at higher doses does not act as a CB1 receptor inverse agonist and does not produce any physiological effects of its own.
NESS 0327 is supplied as a crystalline solid. A stock solution may be made by dissolving the NESS 0327 in an organic solvent purged with an inert gas. NESS 0327 is soluble in organic solvents such as ethanol, DMSO, and dimethyl formamide (DMF). The solubility of NESS 0327 in ethanol and DMSO is approximately 0.25 mg/ml and approximately 0.5 mg/ml in DMF. If aqueous stock solutions are required for biological experiments, they can best be prepared by diluting the organic solvent into aqueous buffers or isotonic saline. Ensure that the residual amount of organic solvent is insignificant, since organic solvents may have physiological effects at low concentrations. We do not recommend storing the aqueous solution for more than one day.
