Custom Phospho-Specific Antibody Service


  Our Services  


Post-translational modification, especially phosphorylation of proteins critical for the biological function of proteins,It plays an important role in  in regulatory mechanisms of life phenomena such as signaling, cell cycle, proliferation, metabolism, growth & development and cancer mechanisms. Dia-an provides site-specific antibody customization service.The prepared modified site-specific antibody does not recognize non modified antigen, has high specificity and sensitivity,

A variety of modified antibody services are available, including:


  • phosphorylation modified specific antibody
  • methylation modified specific antibody
  • acetylation modified specific antibody
  • succinylation modified specific antibody
  • specific antibodies modified by ubiquitination
  • specific antibodies modified by palmitic acid


Our advantages:



  • Analysis of antigen sequence, with help of professional software to design antigen, combined with literature, comprehensively select immunogen sequence, FOR FREE 
  •   P rovide high-quality peptide antigen,  the purity is  > 90% 
  •   coupling protocol is selected from a variety of carrier proteins and coupling methods, and the coupling rate is > 80%
  • Immunize 4 rabbits (to avoid the difference of immune effect caused by animal differences), 2 rabbits with high titer are preferred for purification
