Over the years, KMD Bioscience has provided customers with a wide range of customised phosphorylated monoclonal and polyclonal antibodies. Based on our advanced technologies and extensive experience, KMD Bioscience can provide antibody services for specific phosphorylation sites with a 99.99% success rate. Comprehensive phosphorylation antibody validation services are available, including phosphorylation and non-phosphorylation antigen cross-reactivity, Western Blot and immunohistochemistry.
Phosphorylated Antibody Production Services:
Protein phosphorylation is a significant post-translational modification (PTM) in cells, mainly involved in regulating protein biological activity, including activation or inhibition of protein activity, thereby further regulating the cellular signal pathway. In eukaryotes, the phosphorylation sites of proteins are serine, threonine and tyrosine; in prokaryotes, the phosphorylation site is mainly histidine. You have various protocols to choose for phosphorylated antibody production, including traditional antibody development, such as murine monoclonal hybridoma development technologies and polyclonal antibody development technologies, as well as recombinant antibody development technologies.
Phosphorylated antibody development services based on traditional antibody production techniques:
Analysis of phosphorylation sites; design and synthesis of phosphorylated and non-phosphorylated polypeptide antigens; animal immunization and serum titer evaluation; antibody purification and pairing services.
