Electrophoretic Mobility Shift Assay (EMSA), also known as gel shift or band shift assay, is a molecular biology technique. It’s used to study protein–DNA interactions by observing changes in the mobility of DNA fragments in an electrophoresis gel when proteins bind to them, helping analyze DNA-protein interactions. This is an […]
Enzyme-Linked Immunosorbent Assay (ELISA) is a biochemical test used to detect and quantify specific proteins, antibodies, or antigens in biological samples. It involves using antibodies and enzymes to create a color change that indicates the presence and concentration of the target molecule, making it valuable in various research and diagnostic […]
The CRISPR-Cas (Clustered Regularly Interspaced Short Palindromic Repeats and CRISPR-associated proteins) system is a revolutionary genome editing tool in molecular biology. It enables precise modification of DNA sequences in living organisms, allowing for gene insertion, deletion, or replacement. Cas proteins, guided by RNA molecules, target specific DNA sequences for modification, […]
Cre-lox recombination is a genetic engineering technique used to manipulate DNA in living organisms. It involves the enzyme Cre recombinase, which recognizes specific DNA sequences (loxP sites) to excise, insert, or invert genetic segments. It is valuable for conditional gene knockout and controlled gene expression in research and biotechnology. This […]
The central dogma of molecular biology is a fundamental concept that describes the flow of genetic information in cells. It states that DNA encodes genetic instructions, which are transcribed into RNA, and then translated into proteins. This unidirectional process governs how genetic information is used to build and regulate living […]
