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: (S)-(-)-Propranolol is the active enantiomer of propranolol, a beta -adrenergic receptor antagonist with log Kd values of -8.16, -9.08, and -6.93 for beta 1, beta 2, and beta 3, respectively. It is also a non-specific serotonin receptor antagonist. Propanolol was one of the first beta -adrenergic receptor blockers to be widely used in clinical practice for the treatment of hypertension, angina pectoris, and cardiac ischemia.
(S)-(-)-Propranolol (hydrochloride) is supplied as a crystalline solid. A stock solution may be made by dissolving the (S)-(-)-propranolol (hydrochloride) in the solvent of choice. (S)-(-)-Propranolol (hydrochloride) is soluble in organic solvents such as ethanol, DMSO, and dimethyl formamide, which should be purged with an inert gas. The solubility of (S)-(-)-propranolol (hydrochloride) in these solvents is approximately 11, 16, and 14 mg/ml, respectively. Further dilutions of the stock solution into aqueous buffers or isotonic saline should be made prior to performing biological experiments. Ensure that the residual amount of organic solvent is insignificant, since organic solvents may have physiological effects at low concentrations. Organic solvent-free aqueous solutions of (S)-(-)-propranolol (hydrochloride) can be prepared by directly dissolving the crystalline solid in aqueous buffers. The solubility of (S)-(-)-propranolol (hydrochloride) in PBS, pH 7.2, is approximately 5 mg/ml. We do not recommend storing the aqueous solution for more than one day.
