- From Ron: KT3, His, VSV-G, S-tag, V5, HSV, T7, DDDK, Glu-Glu, HA, E-tag, Myc
- Of these tags, I think the widely used ones are FLAG, His, Myc, HA, and V5.
Parts that have been designed
The optimal second codon is AAA (Lys) in E. coli. So perhaps make all head domains start with Met-Lys?
- His tag: Part:BBa_T2000 | Part:BBa_T2001 | Part:BBa_T2002 (7xHis)
- FLAG tag: Part:BBa_T2003 | Part:BBa_T2004 | Part:BBa_T2005 (DYKDDDDK)
- C-Myc: Part:BBa_T2006 | Part:BBa_T2007 | Part:BBa_T2008 (EQKLISEEDL)
- HA tag: Part:BBa_T2009 | Part:BBa_T2010 | Part:BBa_T2011 (YPYDVPDYA)
- Strep-tag: Part:BBa_T2012 (WRHPQFGG, originally selected as AWRHPQFGG; can only be a tail domain)
- Strep-tag II: Part:BBa_T2013 | Part:BBa_T2014 (WSHPQFEK)
- S-tag: Part:BBa_T2015 | Part:BBa_T2016 | Part:BBa_T2017 (KETAAAKFERQHMDS)
- V5: Part:BBa_T2018 | Part:BBa_T2019 | Part:BBa_T2020 (GKPIPNPLLGLDST)
- VSV-G: Part:BBa_T2021 | no head domain | Part:BBa_T2022 (YTDIEMNRLGK)
