Stable RNAi Cell Line Generation: Stable Gene Knockdown
RNA interference (RNAi) is a cellular process in which gene expression is reduced in a sequence specific manner following the expression of short-hairpin RNA (shRNA) within the cell. Transfection of a plasmid DNA construct containing shRNA and an antibiotic resistant gene induces the knockdown gene expression of the gene of interest and enables selection and isolation of successfully transfected cells. Cells with a prolonged ability to proliferate in the presence of a selecting agent (antibiotic) are capable to initiate a stable RNAi gene knockdown cell line. This important research tool has been vital to the studying of mammalian gene function and gene targeting for potential therapeutic treatments.
Altogen Labs offers generation of stable RNAi cell lines expressing shRNAs targeting genes of interest. Such stable RNAi cell lines can be a powerful research tool, however, the generation of RNAi cell lines and primary cells can be very laborious, expensive, and time-consuming to produce. Development of stably expressing cell lines is important for long term research involving the investigation of the biological impact of gene and protein expression levels. The distinction of a stable cell line is that the exogenous genetic material (in this case shRNA) has been fully incorporated into the genome of the cell resulting in permanent expression of the vector (plasmid DNA construct).
Altogen Labs offers the generation of stable knockdown (RNAi) cell lines based on individual client requirements and project specifications. Validation of gene silencing is performed using real-time qRT-PCR (mRNA expression level) or Western blot (protein expression level). Company scientists bring years of extensive cell culture experience and cell line development expertise.
