Scientists from Harvard University have developed two methods for real-time observation of single-molecule gene expression in living cells by circumventing some of the inherent problems of well-known reporter molecules, according to separate research papers published this week.

The methods are significant because they may allow researchers to obtain quantitative data on single molecular events such as protein production, as opposed to the more commonly used method of averaging together data from multiple gene expression events.
