Answers.Text: Thank you M__ for pointing out this is not (entirely) a bioinformatics question. I have gone ahead and asked the same question in the biology section, and got very useful information. You are absolutely right that this is a very specialized area. Going through the papers, it appeared to me that this problem can only be solved if possible at all via a cross-disciplinary approach, and bioinformatics is one of the key.

Body: <p>We have been using pAbs from an immunized goat for quite a few years but now the goat died. We only have the antigen affinity purified pAb proteins. Is it possible to obtain the sequences?</p>
  <p>We have immunized several other goats, the resulting pAbs performed far worse than the one 'golden goat' produced.</p>
  <p>Thank you.</p>
