  • Immunohistochemistry Services

  • 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: CP 724,714 is a selective inhibitor of HER2/ErbB2 with an IC50 value of 10 nM. It demonstrates greater than 640-fold selectivity against EGFR, InsR, IRG-1R, PDGFR, VEGFR2, Abl, Src, and c-Met. CP 724,714 has been shown to inhibit the proliferation of ErbB2-amplified cells, including BT474 and SK-BR-3 with IC50 values of 0.25 and 0.95 µM, respectively. It also demonstrates antitumor activity in various human tumor xenograft models. However, CP 724,714 was discontinued from clinical development due to hepatotoxicity caused by its ability to inhibit hepatic efflux transporters at low micromolar concentrations.

Usage Information

CP 724,714 is supplied as a crystalline solid. A stock solution may be made by dissolving the CP 724,714 in the solvent of choice. CP 724,714 is soluble in organic solvents such as ethanol, DMSO, and dimethyl formamide (DMF), which should be purged with an inert gas. The solubility of CP 724,714 in ethanol is approximately 2 mg/ml and approximately 3 mg/ml in DMSO and DMF. CP 724,714 is sparingly soluble in aqueous buffers. For maximum solubility in aqueous buffers, CP 724,714 should first be dissolved in DMF and then diluted with the aqueous buffer of choice. CP 724,714 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.
