Leading Manufacturer of Cell Specific Transfection Reagents
Altogen Biosystems is a biotechnology company that develops and manufactures transfection kits for life sciences research, drug discovery and development. Cell transfection kits are pre-optimized for specific cell lines and primary cultures. Altogen® in vivo transfection reagents provide delivery of biomolecules into target tissues. 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 (DNA, RNA, or protein) 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 products for more than 120 cell types, and tissue-targeted in vivo applications.
Laboratory contract research services (Biology CRO Services) are provided by Altogen Labs – our GLP-compliant services include pre-clinical pharm/tox (IND) studies, assay development (ELISA, IC50, qPCR), xenograft animal models, RNAi and gene silencing services. Altogen’s cell culture scientists transform cell lines of choice to stably express gene of interest via development of stable cell line in just 28 days.
Altogen’s nanoparticle-, lipid-, and polymer-based transfection reagents enable the delivery of functional DNA and RNA (mRNA, siRNA, shRNA, microRNA) molecules in vivo for animal research. The PEG-Liposome delivery system reduces innate immune responses due to PEG modification, and provides highly efficient in vivo tissue delivery.
