Transfection Efficiency

Transfection efficiency is the proportion of cells in a biological sample that successfully take up and express introduced nucleic acids, making it a key measure of gene-delivery performance. It depends on factors such as the delivery method, nucleic-acid type, cell condition, and the interaction between genetic material and its carrier; expression is commonly assessed with a reporter gene or other measurable signal. In biology, comparing transfection efficiency helps researchers optimize plasmid DNA, messenger RNA, or small interfering RNA delivery for gene-function studies, protein production, disease modeling, and therapeutic research. Reliable measurements also support reproducible interpretation of experimental results.

We present our optimized high-throughput nucleofection protocol as an efficient way of transfecting primary human monocyte-derived dendritic cells with either plasmid DNA or siRNA without causing cell maturation. We further provide evidence for successful siRNA silencing of targeted gene RIG-I at both the mRNA and protein levels.

An Introduction to Transfection

0 Views •

2023

Transfection is the process of inserting genetic material, such as DNA and double stranded RNA, into mammalian cells. The insertion of DNA into a cell enables the expression, or production, of proteins using the cells own machinery, whereas insertion of RNA into a cell is used to down-regulate the production of a specific protein by stopping translation. While the site of action for transfected RNA is the cytoplasm, DNA must be transported to the nucleus for effective transfection. There, the...

Neuronal Transfection Methods

Transfection - the process of transferring genetic material into cells - is a powerful tool for the rapid and efficient manipulation of gene expression in cells. Because this method can be used to silence the expression of specific proteins or to drive the expression of foreign or modified proteins, transfection is an extremely useful tool in the study of the cellular and molecular processes that govern neuron function. However, mature neurons have a number of properties that make them...
