Purification Method: Egg-yolk derived IgY Affinity Purified.
Source: A chicken was immunized with a peptide representing the splice junction of osteopontin-c (Ac-SEEKQNAVSC-COOH). After multiple immunizations, eggs were collected and IgY was purified from the egg yolk. The antibody was affinity purified on an osteopontin-c peptide column.
Formulation: Phosphate buffered saline‚ pH 7.2 with 0.075% sodium azide.
