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".
Human (tested or 100% immunogen sequence identity)
Monkey (at least 90% immunogen sequence identity)
Specificity and Use
PTGER4 / EP4 antibody was raised against synthetic peptide corresponding to aa 1-23 (M1STPGVNSSASLSPDRLNSPVT23) of human EP4 receptor. Percent identity by BLAST analysis: Human (100%); Chimpanzee, Gorilla, Marmoset (95%); Gibbon, Monkey (91%); Panda (82%).
Recognizes human monocytes and neutrophils, U937 cells and MonoMac cells.
PTGER4 / EP4 is a member of the G-protein coupled receptor family. This protein is one of four receptors identified for prostaglandin E2 (PGE2). This receptor can activate T-cell factor signaling. It has been shown to mediate PGE2 induced expression of early growth response 1 (EGR1), regulate the level and stability of cyclooxygenase-2 mRNA, and lead to the phosphorylation of glycogen synthase kinase-3.
