A Guide to RayBiotech Phosphorylation Assays

Protein phosphorylation plays a prominent role in cell signaling, development and growth. RayBiotech provides a line of phosphorylation immunoassays for monitoring pathway activation, offering a rapid and convenient alternative to standard immunoprecipitations and Western blots.

Phospho Antibody Arrays

Study multiple phosphorylated proteins at one time

Sandwich-based ELISAs

Screen different lysates without performing a Western blot analysis

Cell-based ELISAs

Detect phosphorylated proteins in adhered cells

Kinase Activity Assays

Analyze the activity of kinases

Quantitative Sandwich-based Phospho ELISAs

Determine the concentration of your protein-of-interest
