Eppendorf International last week launched its DualChip Human RNAi Side Effect array. The two-array gene chip utilizes gene expression analysis to detect side effects caused by RNAi molecules in the cell such as proliferation, differentiation, or apoptosis, the company said.

Eppendorf added that the array is suited for scientists in the fields of gene functionalization, target identification and validation, and lead optimization.

BD Biosciences Clontech has recently introduced BD Knockout Gene-Specific kits.
