Human Phospho-Receptor Tyrosine Kinase Array Kit


R&D Systems™ Human Phospho-Receptor Tyrosine Kinase (RTK) Array Kit (Catalog # ARY001B) is a screening tool designed to simultaneously detect the relative phosphorylation of 49 different RTKs. This kit eliminates the need for numerous immunoprecipitation (IP) and/or Western blot experiments. RTKs are captured by antibodies spotted on a nitrocellulose membrane. Levels of Phospho-RTK are then assessed using an HRP-conjugated pan phospho-tyrosine antibody followed by chemiluminescence detection.

General Assay Principle

Carefully selected capture antibodies have been spotted in duplicate on nitrocellulose membranes. Cell lysate samples are diluted and mixed with a cocktail of biotinylated detection antibodies. The sample/antibody mixture is then incubated with the array. Any protein/detection antibody complex present is bound by its cognate immobilized capture antibody on the membrane. Streptavidin-Horseradish Peroxidase and chemiluminescent detection reagents are added, and a signal is produced in proportion to the amount of cytokine bound. Chemiluminescence is detected in the same manner as a Western blot.
