Dharmacon is seeking to set standards for siRNA function.

At his presentation to the Beyond Genome conference at San Diego's civic center June 16, Dharmacon executive vice president of R&D Bill Marshall outlined these standards.

First, the company is recommending that researchers use 100 nanomols of siRNA. "We've selected 100 nanomols because what we've found is by the 100 nanomol point, you have reached a plateau of the inherent functionality of any siRNA sequence," Marshall told GenomeWeb.
