What is the best restriction enzyme?
What is the best restriction enzyme?
Your best choice would be a restriction enzyme within the multiple cloning sequence (MCS) e.g. EcoRI and HindIII. This will give you a number of advantages: MCS is within the lacz gene. This means you can use blue-white selection in E.
What type of enzyme cleaves?
restriction enzyme
restriction enzyme, also called restriction endonuclease, a protein produced by bacteria that cleaves DNA at specific sites along the molecule. In the bacterial cell, restriction enzymes cleave foreign DNA, thus eliminating infecting organisms.
Is PstI a restriction enzyme?
PstI is a type II restriction endonuclease isolated from the Gram negative species, Providencia stuartii.
What are the 3 restriction enzymes?
Today, scientists recognize three categories of restriction enzymes: type I, which recognize specific DNA sequences but make their cut at seemingly random sites that can be as far as 1,000 base pairs away from the recognition site; type II, which recognize and cut directly within the recognition site; and type III.
What is the original bacterial source of the PstI enzyme?
Providencia stuartii
Product Source A E. coli strain that carries the PstI gene from Providencia stuartii 164 (ATCC 49762).
What does PstI stand for?
PSTI
| Acronym | Definition |
|---|---|
| PSTI | Patient Specific Therapeutic Interchange |
| PSTI | Precise Software Technologies Inc (software developers; Ottawa, Ontario, Canada; est. 1989) |
| PSTI | Petroleum Science and Technology Institute (UK) |

Does PstI have a high fidelity version?
Product Information PstI has a High Fidelity version PstI-HF ® (NEB #R3140). High Fidelity (HF) Restriction Enzymes have 100% activity in CutSmart Buffer; single-buffer simplicity means more straightforward and streamlined sample processing. HF enzymes also exhibit dramatically reduced star activity.
What is one unit of PSTI?
One unit is defined as the amount of PstI required to digest 1 µg of λ DNA in 1 hour at 37°C in a total reaction volume of 50 µl. May exhibit star activity in rCutSmart Buffer. Not sensitive to CpG, dcm, or dam methylation. Why Choose Recombinant Enzymes? What is the activity of PstI at 25°C? Is PstI used in special techniques?
What is the relationship between E coli plasmids and genes?
In principle, most E. coli genes should be carried by one or more plasmids in this collection, but the problem is that only a small proportion of the plasmids have been characterized with regard to identifying the particular E. coli segment that is present in individual plasmids.
