Also in the early 1990s, scientists were learning about the ability of plasmid DNA to stimulate both humoral immunity (antibodies) and cell-mediated immunity (T cells) and thus the potential for plasmids to be used as vaccines. In this case, the plasmids are designed to produce specific proteins from the relevant pathogen and then purified.The plasmid is an extrachromosomal DNA which means it is not a chromosome and can replicate independently of the chromosome. It is a small circular DNA strand in a bacterium's cytoplasm. The ...Dec 24, 2022 · The term plasmid was first introduced by the American molecular biologist Joshua Lederberg in 1952.

Plasmids naturally exist in bacterial cells, and they also occur in ...Key points: Restriction enzymes are DNA-cutting enzymes. Each enzyme recognizes one or a few target sequences and cuts DNA at or near those sequences. Many restriction enzymes make staggered cuts, producing ends with single-stranded DNA overhangs. However, some produce blunt ends. DNA ligase is a DNA-joining enzyme.Plasmid pLKO.1 GFP shRNA from Dr. David Sabatini's lab contains the insert GFP shRNA and is published in Science. 2008 Jun 13. 320(5882):1496-501. This plasmid is available through Addgene.TOPO® Cloning. Toposiomerase based cloning, often called TOPO® cloning or TA cloning, is a method that relies on the hybridization of the complementary base pairs adenine (A) and thymine (T). TOPO® cloning utilizes the Taq polymerase which naturally leaves a single adenosine (A) overhang on the 3' end of PCR products.The Cre/lox system is a well-established research tool, especially in the field of mouse transgenics. A few of the most common uses are listed below. Cre-dependent gene expression – placing a stop codon with loxP sites on either side (often called a “lox-stop-lox” or “LSL” cassette) upstream of a gene of interest will prevent gene ...All plasmids are compatible with standard cloning, LIC, InFusionHD, Gibson Assembly, Seamless Geneart.
