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.
Why use pGEM-t Easy vector?
The pGEM®-T Easy Vector Systems offer all of the advantages of the pGEM®-T Vector Systems with the added convenience of recognition sites for BstZI, EcoRI and NotI flanking the insertion site. Thus, several options exist to remove the desired insert DNA with a single restriction digestion.
Is pGEM-T Easy used in TA cloning?
Plasmid: pGEM-T Easy Vector This allows the insert DNA to be removed with a single restriction digest using either of these enzymes. Parental vector for TA cloning of PCR products.
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 a TA vector?
T vectors are linearized plasmids that have been treated to add T overhangs to match the A overhangs of the PCR product. PCR fragments that contain an A overhang can be directly ligated to these T-tailed plasmid vectors with no need for further enzymatic treatment other than the action of T4 DNA ligase.
What is TA cloning used for?
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 the importance of the f1 origin for the plasmid?
The purpose of the f1 ori in the pEGFP plasmid is to facilitate ssDNA replication and phage packaging [53, 60].
What is TA in genetics?
What is TOPO TA cloning used for?
TA cloning is a simple method to clone any desirable fragment with an extra A (Adenine nucleotide) overhang into any linearized vector with T (Thymidine nucleotide) overhang. TOPO TA cloning is restriction digestion-free and ligation-free cloning.
What is the MCS in plasmid?
A multiple cloning site (MCS), also called a polylinker, is a short segment of DNA which contains many (up to ~20) restriction sites – a standard feature of engineered plasmids. Restriction sites within an MCS are typically unique, occurring only once within a given plasmid.
What is TA cloning kit?
The TA Cloning™ Kit uses the pCR™2.1 cloning vector and ExpressLink™ T4 DNA Ligase to generate a ligation product in a fifteen-minute, room-temperature ligation step. Reactions typically yield >80% recombinants containing inserts.
What is the pGem-T easy vector system?
The pGEM-T Easy Vector Systems are convenient systems for cloning PCR products. They offer all of the advantages of the pGEM-T Vector Systems with EcoRI and NotI sites flanking the insertion site. The pGEM-T Easy Vector Systems are convenient systems to clone PCR products.
What is the ligation buffer for pGem ®-T easy vector systems?
The pGEM ® -T and pGEM ® -T Easy Vector Systems include a 2X Rapid Ligation Buffer for ligation of PCR products. Reactions using this buffer may be incubated for 1 hour at room temperature. The incubation period may be extended to increase the number of colonies after transformation. 1.
How is the pGem®-T easy vector multiple cloning region structured?
The pGEM®-T Easy Vector multiple cloning region is flanked by recognition sites for the restriction enzymes EcoRI, BstZI and NotI, providing three single-enzyme digestions for release of the insert. The pGEM®-T Vector cloning region is flanked by recognition sites for the enzyme BstZI.
