Basically we accept proteins dissolved in a kind of buffer, and the buffer may contain <1% detergent, <4M urea to make the protein soluble if needed. Protein in PAGE gel band can be used for rabbit immunization, but it's not recommended because of the difficulties in quantity determination, emulsification and lower success rate. To ensure high level of specific antibody to the target protein, >85% purity is required for protein antigen in polyclonal antibody production.
