Chickens were immunized with a synthetic peptide containing the influenza hemagglutinin (HA) epitope (i.e., YPYDVPDYA) conjugated to keyhole limpet hemocyanin. The first injection included complete Freund’s adjuvant; subsequent injections included incomplete Freund’s adju­vant. Eggs were collected after the fourth injection, and antibodies were purified from the yolks using a proprietary method that yields a purity of >90%.  Antibodies were affinity-purified over a peptide column and then dialyzed against phosphate-buffered isotonic saline. Sodium azide was added and the antibod­ies were filter-sterilized (0.2 µm).


Phosphate-buffered saline (PBS) (pH 7.2), sodium azide (0.02%, w/v) (as an anti-microbial agent).

Store at 4°C in the dark. Under these conditions, the antibodies should have a shelf life of at least 12 months (provided they remain sterile). For longer storage periods, dilute the antibodies with sterile glycerol and store at -20°C. Do not freeze these antibodies unless you want to store them for longer periods of time.
