Phospho-Specific Antibody Platform

Over the years, KMD Bioscience has provided customers with a wide range of customized phospho-specific monoclonal and polyclonal antibodies. Based on our advanced antibody discovery technologies and extensive experience, KMD Bioscience can provide antibody discovery services for phospho-specific sites with a 99.99% success rate. Comprehensive phospho specific antibodies validation services are available, including phosphorylation and non-phosphorylation antigen cross-reactivity, Western Blot, and immunohistochemistry.

 

Phospho-Specific Antibody Production Service

 

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 phospho-specific sites of proteins are serine, threonine, and tyrosine; in prokaryotes, the phospho-specific site is mainly histidine. You have various protocols to choose for phospho 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.

Phospho-specific 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.
