What is pGEM easy vector?
The pGEM®-T Easy Vector Systems are convenient systems to clone PCR products generated by certain thermostable polymerases. These polymerases often add a single deoxyadenosine, in a template-independent fashion, to the 3´-ends of the amplified fragments.
What is the size of the pGEM T Easy vector?
Plasmid: pGEM-T Easy Vector
|5′ Sequencing 1 Primer:||T7, SP6, M13Fwd or M13Rev|
Is pGEM T Easy used in TA cloning?
One of the easiest methods for cloning blunt-ended DNA fragments including PCR products is T-vector cloning, such as with pGEM®-T or pGEM®-T Easy Vector Systems. This method takes advantage of the “A” overhang added by a PCR enzyme like Taq DNA Polymerase.
What is a pET vector?
The pET vector system is a powerful and widely used system for expressing recombinant proteins in E. coli. The gene of interest is cloned into the pET vector under the control of the strong bacteriophage T7 transcription and translation regulatory system.
What gene does pGEM t easy carry?
The pGEM®-T Vectors carry a segment of the lacZ gene that encodes the amino terminal fragment of beta-galactosidase.
What is the purpose of TA cloning?
Abstract. TA cloning is one of the simplest and most efficient methods for the cloning of PCR products. The procedure exploits the terminal transferase activity of certain thermophilic DNA polymerases, including Thermus aquaticus (Taq) polymerase.
What is difference between plasmid and vector?
The main difference between plasmid and vectors is that plasmid is an extra-chromosomal element of mainly bacterial cells whereas vector is a vehicle that carries foreign DNA molecules into another cell. Plasmids can also be used as vectors.
What is pET system?
The pET System is the most powerful system yet developed for the cloning and expression of recombinant proteins in Escherichia coli Target genes are cloned in pET plasmids under control of strong bacteriophage T7 transcription and (optionally) translation signals, expression is induced by providing a source of T7 RNA …
What feature makes the pGEM T vector suitable for ligation of PCR products?
The pGEM®-T Easy pre-linearized Vector contains 3´-T overhangs at the insertion site to provide a compatible overhang for PCR products. The provided 2X Rapid Ligation Buffer allows reactions to be completed in 1 hour at room temperature.
What is TA cloning explain its steps?
TA cloning is one of the simplest and most efficient methods for the cloning of PCR products. The procedure exploits the terminal transferase activity of certain thermophilic DNA polymerases, including Thermus aquaticus (Taq) polymerase.
