2-chicken 80-day chicken immunization protocol

This chicken immunization schedule uses two White Leghorn chickens. Animals are housed individually in separate cages, injections are subcutaneous (SQ) as emulsions in Complete Freund’s Adjuvant (CFA) or Incomplete Freund’s Adjuvant (IFA); alternative adjuvants can be used upon request. Customizations to the protocol are available. For example, you can choose the number of chickens needed and you can adjust the length of your protocol beyond the 80-day immunization schedule to meet your research goals. Please contact us to discuss the options in detail. Antigen preparation, such as peptide synthesis and/or immunogen conjugation, occurs before day 0. Protocols days are approximate (± 2 days).
