SiRNA Transfection protocol technique method in vivo

Welcome to siRNA transfection resource.  In biomedical applications, this process of RNA interference has encouraged researchers to study ways in which this process can be utilized to shut down or effectively incapacitate a defective or non-wanted gene’s ability to replicate. These studies focus on conditions such as cancer and autoimmune diseases. Research is underway by academic institutions and pharmaceutical companies around the world to utilize the testing of RNAi-based functions and RNAi therapies to treat conditions such as viral infections and cancer. Small interfering RNA, more commonly known as, belong to a class of double-stranded RNA molecules, known as silencing RNA. Commonly studied and analyzed in the field of molecular biology, siRNA defines a mechanism of cellular replication (or inhibition) that has been greatly utilized in research of antiviral defense mechanisms. siRNA is vastly utilized in molecular genetics as a research tool in RNAi technologies and studies.

We introduce a simple and cost-effective technique for the efficient transient transfection of suspension cells through the coating of cell culture plates with chicken egg white.

The method is characterized by minimal toxicity and correct gene expression. Although established for the mast cell line C7 and the myeloid cell line HL-65 the technique is likely to be used for other suspension cell lines as well. Our improved protocol demonstrates that the overcoming of the non-adherent character of suspension cells substantially supports transfection efficiency, and that this can be achieved by a simple chicken egg white-based system. However, not all transfection methods can be applied to all types of cells, and there is a wide variation with respect to the achieved cell viability and the expression level of the gene of interest. The determination of the most appropriate transfection technique depends on several factors, such as the cell type or the adherence ability of the cells. Suspension cell lines have traditionally proven to be very difficult to transfect. Here we present an efficient transfection method for suspension cell lines (please see our protocol for details).

Close Mammalian cell transfection is a technique commonly used to express exogenous DNA or RNA in a host cell line (for example, for generating RNAi probes ). There are many different ways to transfect mammalian cells, depending on the cell line characteristics, desired effect, and downstream applications. In this article, I will review the different methods of expressing exogenous DNA or RNA sequences in mammalian cells. These methods can be broadly divided into two categories: those used to generate transient transfection, and those used to generate stable transfectants. Transient transfections are most commonly used to investigate the short-term impact of alterations in gene and protein expression. Plasmid DNA (pDNA), messenger RNA (mRNA), short-interfering RNA (siRNA), short-hairpin RNA (shRNA) and microRNA (miRNA) are commonly used in transfection experiments. During transient expression, however, the nucleic acid sequence is not integrated into the host cell genome. On the other hand, when long-term expression of the sequence is desired, stable transfection protocols are used to generate permanent expression in cell lines. In this case, the transfected genetic material is integrated into the host cell genome. A selection marker is used to identify cells that have successfully integrated the sequence of interest.

The selecting agent enriches and enables the growth of a subpopulation where the exogenous genetic material has been incorporated into the genome. Transfection of DNA or RNA molecules into cultured mammalian cells can be accomplished using various methods and reagents.
