  • 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: Lysophosphatidic acid (LPA) is a potent lipid mediator that elicits its effect through four distinct receptors - LPA1/EDG-2, LPA2/EDG-4, LPA3/EDG-7 and LPA4/GPR23. OMPT is a selective agonist of the lysophosphatidic acid 3 (LPA3) receptor. It exhibits EC50 values of 68 nM and >6.8 µM for calcium mobilization in LPA1 and LPA2-expressing Sf9 cells, respectively. The (2S)-OMPT enantiomer is 5- to 20-fold more active than (2R)-OMPT in calcium release assays in both LPA3-transfected Sf9 and rat hepatoma Rh7777 cells. H5_ChemicalStructureImage.png

Usage Information

(2S)-OMPT is supplied in a (1:1) solution of ethanol:chloroform. To change the solvent, simply evaporate the ethanol:chloroform under a gentle stream of nitrogen and immediately add the solvent of choice. Solvents such as ethanol, DMSO, and dimethyl formamide purged with an inert gas can be used. The solubility of (2S)-OMPT in these solvents is at least 30 mg/ml. 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. If an organic solvent-free solution of (2S)-OMPT is needed, it can be prepared by evaporating the ethanol:chloroform and directly dissolving the neat oil in aqueous buffers. The solubility of (2S)-OMPT in PBS (pH 7.2) is at least 10 mg/ml. We do not recommend storing the aqueous solution for more than one day.
