Overview of dsRNA dsRNA molecules consist of two complementary strands that form a helical structure, resembling the double helix of DNA. They play a critical role in RNA interference (RNAi), a biological process used by cells to regulate gene expression and defend against viral infections. ...
This approach allows for the activation of endogenous genes without altering their DNA sequence, making it a valuable tool for studying gene function in a more natural context. ...
Transfection, the first step in the process, involves the introduction of a foreign plasmid (DNA molecule) into a host cell. The plasmid carries the gene coding for the protein of interest, and the cell's machinery copies this gene and uses it as a blueprint to manufacture the protein. This procedure is a delicate balancing act, with scientists ...
The Mechanism Ionic channels expression systems function based on recombinant DNA technology. They utilize plasmid vectors---vessels that carry the genes of interest---to express the required ionic channels. Researchers introduce these plasmids into host cells, usually bacterial or mammalian, where they target the cell's genetic machinery to ...
The clinical sample types generally include fresh or frozen tissue that often yield high quality DNA and samples that often yield low quantity and/or compromised quality DNA like FFPE (formalin-fixed paraffin-embedded) tissue, decalcified FFPE tissue, bone marrow trephines, smears, and fine needle aspirates (FNA), plasma, and circulating tumor cells. Some studies ...
Type II restriction enzymes have been widely used in DNA molecular cloning and sequence analysis because they do not require ATP to hydrolyze DNA and do not methylate or otherwise modify DNA. ...
In recent years, a variety of strategies have been used for mRNA delivery, and most of these methods are inspired by siRNA and plasmid DNA delivery technologies. Difficulties in mRNA vaccine delivery As a new type of therapeutic drug, mRNA has great potential in vaccine research. ...
The growing pipeline of cell and gene therapy therapies has led to an increase in demand for gene delivery vehicles such as plasmid DNA (pDNA), messenger RNA (mRNA) and viral vectors. They can be used as stand-alone treatments or can be used as starting materials required for further processing of cell and gene therapeutics. ...
Given the height of the bacteriophage M13 (3-4 nm), a single bacteriophage may have been imaged at 1720 cm-1 (C=O) and 1667 cm-1 (amide I) via PiFM. As is the case in many instances, PiFM images reveal features that are not clear in ...
