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: Adenosine 5'-(γ-thio)-triphosphate (lithium salt) is a stable analog of ATP that acts as a potent agonist of G protein-coupled P2Y2 and P2Y11 receptors (pEC50 = 5.52 for P2Y11). It has been used to identify kinase substrates, has been implemented as a reagent in the synthesis of DNA N-acetylglucosamine analogs, and can serve as a substrate for the RNA-stimulated nucleotide hydrolysis and RNA unwinding activities of eukaryotic initiation factor-4A.
P'-anhydride with phosphorothioic acid adenosine 5'-(trihydrogen diphosphate), tetralithium salt
ATPγS (lithium salt) is supplied as a crystalline solid. The solubility of ATPγS (lithium salt) in PBS, pH 7.2, is approximately 10 mg/ml. We do not recommend storing the aqueous solution for more than one day.
