New England Biolabs (NEB) is an American life sciences company which produces and supplies recombinant and native enzyme reagents for life science research. [2] It also provides products and services supporting genome editing , synthetic biology and next-generation sequencing . [ 3 ]
HindIII (pronounced "Hin D Three") is a type II site-specific deoxyribonuclease restriction enzyme isolated from Haemophilus influenzae that cleaves the DNA palindromic sequence AAGCTT in the presence of the cofactor Mg 2+ via hydrolysis.
A rare-cutter enzyme is a restriction enzyme with a recognition sequence which occurs only rarely in a genome. An example is NotI, which cuts after the first GC of a 5'-GCGGCCGC-3' sequence; restriction enzymes with seven and eight base pair recognition sequences are often also called rare-cutter enzymes (six bp recognition sequences are much more common).
This is a list of abbreviations used in medical prescriptions, including hospital orders (the patient-directed part of which is referred to as sig codes).This list does not include abbreviations for pharmaceuticals or drug name suffixes such as CD, CR, ER, XT (See Time release technology § List of abbreviations for those).
EcoRI (pronounced "eco R one") is a restriction endonuclease enzyme isolated from species E. coli. It is a restriction enzyme that cleaves DNA double helices into fragments at specific sites, and is also a part of the restriction modification system. [1]
Together, these two processes form the restriction modification system. [6] More than 3,600 restriction endonucleases are known which represent over 250 different specificities. [7] Over 3,000 of these have been studied in detail, and more than 800 of these are available commercially. [8]
Neb may refer to: Neb, transcription of an ancient Egyptian hieroglyph of a basket, Gardiner sign V30; Neb, the pen name of British political cartoonist Ronald Niebour (1903–1972) NEB may refer to: Nose in Everyone's Business, a busybody or gossip; National Enterprise Board, a UK government body from 1975 to 1981
BamHI, like other type II restriction endonucleases, often requires divalent metals as cofactors to catalyze DNA cleavage. [2] Two-metal ion mechanism is one of the possible catalytic mechanisms of BamHI since the BamHI crystal structure has the ability to bind two metal ions at the active site, which is suitable for the classical two-metal ion mechanism to proceed.
