Life Technologies has introduced Invivofectamine 2.0 and Ambion In Vivo siRNA, two products designed to enable gene-knockdown experiments in small animal models.

Sold as part of a 1 mL starter kit or a 5 mL kit, both products are synthetic, contain no components of viral origin, and show minimal to no toxicity after extensive initial studies, the company said.


Altogen Biosystems has released the second generation of its in vivo RNAi transfection reagent for its PEG-liposome siRNA in vivo transfection kit.

The reagent is also compatible for in vivo transfection of other negatively charged molecules such as RNA, DNA, and small proteins, the firm noted.
