Goals of the BBF Measurement Working Group

  • We aim to submit the following standards for comment in advance of the June workshop:
    • the definition of a consensus relative fluorescence unit of measure - a 'Biobricks E. coli GFP fluorescence unit'
    • a standard method for measuring promoter strengths

Briefing on Measuring Promoters & RBSs

  • Video from Jason Kelly introducing a standard measurement kit for characterizing BioBrick promoters and RBSs. (feel free to comment via talk page, blog, email, smoke signal, etc.)
