Donkey anti-sheep IgG (Heavy & Light Chain), Peroxidase Conjugated Affinity-Purified IgG

Store between -10 and -20 °C. Product will become viscous but will not freeze. Avoid storage in frost-free freezers. Keep vial tightly capped. Allow product to warm to room temperature and gently mix before use. Avoid exposure to sodium azide as this is an inhibitor of peroxidase activity.

Immunoelectrophoresis of this antibody prior to conjugation gave a single precipitin line of identical mobility to that obtained with purified sheep IgG. There is 100% cross-reactivity with goat IgG when tested by ELISA.
