Talk:Protein tag

Untitled
What is a poly(NANP) tag? Must have escaped my attention so far, never heard of that. Nor am I able to find it on the internet. Does anyone know? 160.45.25.162 (talk) 17:31, 20 January 2012 (UTC)

I believe this article could benefit from some a brief discussion of methods used to design and express tagged proteins. Also, I believe some protein tags only function when appended to a specific terminus, if so that information should be discussed as well. Hsa-mir-122 (talk) 20:01, 30 September 2013 (UTC)
