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.
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, Mouse, Rat
(tested or 100% immunogen sequence identity)
Western blot (1:1000)
Synthetic peptide (KLH coupled) corresponding to residues surrounding Ser412 of human beta-arrestin 1.
Detects endogenous beta-arrestin 1 only when phosphorylated at Ser412. Does not cross-react with beta-arrestin 2. Species cross-reactivity: Mouse and rat.
Suitable for use in ELISA, Western Blot and Immunoprecipitation. Western Blot: 1:1000, incubate membrane with diluted antibody in 5% BSA, 1X TBS, 0.1% Tween-20 at 4?C with gentle shaking, overnight. Immunoprecipitation: 1:50.
10 mM HEPES, pH 7.5, 150 mM NaCl, 0.1 mg/ml BSA, 0.02% Sodium Azide, 50% Glycerol
Functions in regulating agonist-mediated G-protein coupled receptor (GPCR) signaling by mediating both receptor desensitization and resensitization processes. During homologous desensitization, beta-arrestins bind to the GPRK-phosphorylated receptor and sterically preclude its coupling to the cognate G-protein; the binding appears to require additional receptor determinants exposed only in the active receptor conformation.
