This antibody pair Kit comes with matched antibody pairs to detect and quantify protein levels of soluble c-Met. Activation of c-Met, also known as HGF (hepatocyte growth factor receptor), regulates RAS signalling and cell scattering. Also available is Buffer Kit for Antibody Pairs that saves time with premade, easy-to-use buffers and solutions optimized for use with Invitrogen Antibody Pairs. The Assay Buffer can be used as a blocking reagent for ELISA plates as well as a diluent for ELISA standards and samples, detection antibody, and HRP conjugate. Buffer reagents needed to complete the reaction are sold separately under Catalog #CNB0011.
