An alternative approach to study the enzymatic specificities of the CfrBI restriction–modification system

open access: yesHeliyon, 2019
Restriction–modification systems (RMS) are the main gene-engineering tools and a suitable model to study the molecular mechanisms of catalysis and DNA–protein interactions.

Highly specific PCR-RFLP assays for karyotyping the widespread 2Rb inversion in malaria vectors of the Anopheles gambiae complex [PDF]

open access: yes, 2020
Background: Chromosomal inversion polymorphisms play a role in adaptation to heterogeneous environments. Inversion polymorphisms are implicated in the very high ecological flexibility of the three main malaria vector species of the Afrotropical Anopheles

A one pot, one step, precision cloning method with high throughput capability.

open access: yesPLoS ONE, 2008
Current cloning technologies based on site-specific recombination are efficient, simple to use, and flexible, but have the drawback of leaving recombination site sequences in the final construct, adding an extra 8 to 13 amino acids to the expressed ...

Rapid Generation of Nested Deletions by Differential Restriction Digestion

open access: yesBioTechniques, 2002
A method was devised for generating nested deletions in DNA that exploits the difference in frequency of restriction sites recognized by compatible restriction endonucleases.

Site-specific restriction endonucleases in Bacillus licheniformis [PDF]

open access: yesFEMS Microbiology Letters, 1995
We systematically studied site-specific restriction endonucleases in Bacillus licheniformis strains and detected endonuclease activity in 25 of 217 strains tested. Three different activities were obtained. One of these activities detected in 21 strains was the most representative within the species and produced a banding pattern, after digestion of A ...

Frequencies of restriction sites

open access: yesNucleic Acids Research, 1983
Restriction sites or other sequence patterns are usually assumed to occur according to a Poisson distribution with mean equal to the reciprocal of the probability of the given site or pattern. For situations where non-overlapping occurrences of patterns, such as restriction sites, are the objects of interest, this note shows that the Poisson assumption

Restriction Site-Free Insertion of PCR Products Directionally into Vectors

open access: yesBioTechniques, 2000
A restriction site-free cloning method has been developed for inserting a PCR product into a vector flexibly and precisely at any desired location with high efficiency. The method uses a pair of DNA integration primers with two portions.

Performance and diarrhoea in piglets following weaning at seven weeks of age: Challenge with E. coli O 149 and effect of dietary factors [PDF]

open access: yes, 2009
Four dietary factors (ad libitum versus feed restriction, control versus protein restriction at ad libitum feeding, control versus inclusion of lupine as a protein source at ad libitum feeding, and control versus extra vitamin E at ad libitum feeding ...

Automatic construction of restriction site maps [PDF]

open access: yesNucleic Acids Research, 1982
A computer program is described which constructs maps of restriction endonuclease cleavage sites in DNA molecules, given only the fragment lengths. The program utilizes fragment length data from single and double restriction enzyme digests to generate maps for linear or circular molecules.
