  • 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-5751 is an antagonist of the prostaglandin D2 (PGD2) receptor DP1 (Ki = 1.6 nM) that shows at least 20-fold selectivity over receptors for thromboxane and prostacyclin, as well as the PGE2 receptor EP2. Orally administered S-5751 blocks PGD2-induced plasma exudation in the conjunctiva (ED50 = 0.099 mg/kg) and suppresses antigen-induced allergic responses in guinea pigs. S-5751 has been used to distinguish signaling of PGD2 through its two receptors, DP1 and DP2 (also known as CRTH2). H1_ChemicalStructureImage.png
