Dear All, We are looking to protein tags (of size not exceeding 10 kDa) as markers to label our protein complex of size ~50 kDa. Although I have searched for several possible candidates mainly mini-proteins, most of them are not what we want to have. The features that we are looking in the tag proteins are
1. Stable & Plus-charged proteins. 2. Close distance between N-terminal and C-terminal ends. 3. Possibly with alpha helices. 4. size not exceeding 10 kDa Any suggestion will be very helpful. Thanks in advance and Best Wishes Andy Dr. Anindito Sen (Ph.D) Structural Biology Graduate School of Medicine University of Tokyo 7-3-1 Hongo. Bunkyo-ku. Tokyo 113-0033.
