Altogen Biosystems is a leading manufacturer of cell type-specific, pre-optimized transfection reagents, in vivo transfection kits, and electroporation products for intracellular delivery of biomolecules. Efficient delivery of target molecules (siRNA, DNA, mRNA) enabled by advanced reagent formulation and pre-optimized transfection protocol design. Altogen Biosystems develops liposome-, nanoparticle-, and biodegradable polymer-based transfection technologies by applying combinatorial chemistry, molecular and cell biology expertise. Orders can be placed online at the individual product webpage.

Transfection is the introduction of exogenous molecules (protein, DNA or RNA) into cultured cells and is commonly used to study gene function, modulation of gene expression, biochemical mapping, and protein production. Unfortunately, no single delivery method or transfection reagent can be applied to all types of cells, cellular cytotoxicity and transfection efficiencies vary dramatically and depend on the reagent, protocol, and cell type used. Altogen Biosystems offers pre-optimized transfection kits and electroporation buffers for more than 120 cell types, and tissue-targeted in vivo applications. 

Altogen Labs offers GLP compliant CRO services, pre-clinical toxicology (IND), ELISA assay development, xenograft animal models, RNA interference (RNAi) and gene silencing services (A-to-Z siRNA services: from siRNA design to in vivo validation). Generating stable cancer cell lines and primary cells can be very expensive and time-consuming. Altogen’s cell culture scientists transform cell lines of choice to stably express gene of interest via development of stable cell line in 28 days.

Altogen's nanoparticle-, lipid-, and polymer-based transfection reagents enable the delivery of functional RNA (siRNA, shRNA, microRNA) and DNA molecules in vivo for animal reseach (mouse, rat), including biodistribution and RNAi gene silencing studies. The PEG-Liposome in vivo delivery system reduces innate immune responses due to PEG modification, and provides highly efficient in vivo tissue delivery of siRNA, DNA, and protein.

As featured by Science magazine, Altogen Biosystems offers following in vivo transfection kits for rodent research studies:
