Custom Polyclonal Antibody Service

 

 

  Our Services  

 

Polyclonal antibody can recognize multiple epitopes, and has become an indispensable tool for researchers to carry out immunological research because of its short preparation schedule, low cost and wide application. Relying on the R & D and production experience of 5000 + multi antibody project, Dia-an provide polyclonal antibody preparation from rabbits, rats, mice, guinea pigs, sheep, chickens and other hosts. Various antibodies has been successfully customized against species: human, mouse, rat, zebrafish, crucian carp, grass carp, Pelteobagrus fulvidraco, mandarin fish, sea cucumber, sea urchin, nematode, Tetrahymena, bacteria, virus, Arabidopsis, cyanobacteria, cotton, corn, rice, potato, oil vegetable, wheat, etc.

 

Our advantages:

 

 

  • Analysis of antigen sequence, with help of professional software to design antigen, combined with literature, comprehensively select immunogen sequence, FOR FREE
  • Provide high-quality recombinant protein antigen (prokaryotic/eukaryotic),for immunization,  supernatant expression success rate > 90%, purity > 80%, concentration > 1mg / ml
  • Synthesize high-purity peptide antigen;Small molecule antigens adopt a unique activation and coupling scheme
  • The self-developed adjuvant is used to ensure that the antigen and adjuvant are fully mixed and injected subcutaneously at multiple points, so as to improve the serum titer of animals to the greatest extent
