Antibody Conjugation
Antibody conjugations adapted to your specific requirements. The modifications are available for antibodies that you provide us and that Davids creates for you. Table 1 summarizes the most common modifications for antibodies. If you require different antibody conjugations, please contact us at info@davids-bio.com.

Antigen Conjugation
Antigen conjugation can improve immune response, particularly for antigens with low antigenicity. Small antigens, such as peptides, haptenes, or medicines, can become larger by forming multimers, resulting in a stronger immune response in the majority of situations. For proteins less than 15 kDa, that will be used for immunizations, we propose conjugation to a carrier such as KLH, BSA, Ovalbumin, or Thyroglobulin. Furthermore, a modification for hazardous antigens may be required to minimize toxicity prior to vaccination. Please see our Antigen Page for further information on antigen requirements, or our Peptide Antibody Page for peptide conjugations.
