A cosmid is a type of hybrid plasmid that contains a Lambda phage cos sequence. [1] Often used as cloning vectors in genetic engineering, cosmids can be used to build genomic libraries. They were first described by Collins and Hohn in 1978. [2] Cosmids can contain 37 to 52 (normally 45) kb of DNA, limits based on the normal bacteriophage ...
Lambda phage is a non-contractile tailed phage, meaning during an infection event it cannot 'force' its DNA through a bacterial cell membrane. It must instead use an existing pathway to invade the host cell, having evolved the tip of its tail to interact with a specific pore to allow entry of its DNA to the hosts.
Phage therapy, viral phage therapy, or phagotherapy is the therapeutic use of bacteriophages for the treatment of pathogenic bacterial infections. [1] [2] [3] This therapeutic approach emerged at the beginning of the 20th century but was progressively replaced by the use of antibiotics in most parts of the world after the Second World War.
Phage therapy has gained recent attention in the United States as an alternative to standard antibiotic therapy. [ 5 ] [ 6 ] [ 7 ] It has been in practice for just over 100 years in countries such as Russia and Georgia , but due to the recent clinical attention of antibiotic resistance , Western countries have slowly been integrating phage ...
The earliest identified members of the serine recombinase family were known as resolvases or DNA invertases, while the founding member of the tyrosine recombinases, lambda phage integrase (using attP/B recognition sites), differs from the now well-known enzymes such as Cre (from the P1 phage) and FLP (from the yeast Saccharomyces cerevisiae).
Lambdavirus (synonyms Lambda-like viruses, Lambda-like phages, Lambda phage group, Lambda phage) is a genus of viruses in the class Caudoviricetes. Bacteria serve as natural hosts, with transmission achieved through passive diffusion. There are five species in this genus.
Phage display of antibody libraries has become a powerful method for both studying the immune response as well as a method to rapidly select and evolve human antibodies for therapy. Antibody phage display was later used by Carlos F. Barbas at The Scripps Research Institute to create synthetic human antibody libraries, a principle first patented ...
The founding member of the YR family is the lambda integrase, encoded by bacteriophage λ, enabling the integration of phage DNA into the bacterial genome. A common feature of this class is a conserved tyrosine nucleophile attacking the scissile DNA-phosphate to form a 3'-phosphotyrosine linkage.
