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.
Chickens were immunized with purified, non-denatured goat IgG (containing both heavy and light chains) emulsified in Freund’s adjuvant. After multiple injections, eggs were collected from hyperimmunized hens and the IgY fraction purified from the yolks. Anti-goat IgG’s were affinity-purified over a column conjugated with purified goat IgG (whole protein).
