Recombinant bovine intestinal kinase is widely used in molecular biology and biochemical research for phosphorylation of target proteins and peptides. It plays a critical role in signal transduction studies by mimicking natural phosphorylation processes, allowing researchers to investigate kinase-dependent pathways. This enzyme is particularly useful in assays involving protein activation, enzyme regulation, and cell signaling mechanisms. Its recombinant nature ensures high purity and consistency, making it suitable for in vitro applications such as kinase activity assays, drug screening, and evaluation of kinase inhibitors. Additionally, it supports the production of phosphorylated standards for use in Western blotting, mass spectrometry, and other detection methods requiring phospho-specific antibodies.
