Is CAG a strong promoter?

The CAG promoter is a strong synthetic promoter frequently used to drive high levels of gene expression in mammalian expression vectors.

Is CAG a ubiquitous promoter?

Although the CAG promoter is a ubiquitously active promoter, the effect of methylation is usually, though not always, strong enough to silence the promoter activity and prevent EGFP expression.

How big is the CAG promoter?

Plasmid: CAG promoter

How long does CAG promoter take?

The lengths of the CAG, HEF1‐α, CMV mutant, CHEF‐1α, CAG enhancer, mouse CMV, PGK, and CMV promoter inserts were 1662, 1659, 589, 1335, 287, 523, 555, and 589 bp, respectively. Given that each vector contains different cis‐acting elements, their lengths are different.

What is T7 promoter?

The T7 promoter is a sequence of DNA 18 base pairs long up to transcription start site at +1 (5′ – TAATACGACTCACTATAG – 3′) that is recognized by T7 RNA polymerase1 .

What is T3 promoter?

T3 Promoter. 5′ AATTAACCCTCACTAAAG 3′ T3 RNA polymerase starts transcription at the underlined G in the promoter sequence. The polymerase then transcribes using the opposite strand as a template from 5´→3´. The first base in the transcript will be a G.

What is the T5 promoter?

The IPTG-inducible T5 promoter consists of a strong constitutive promoter flanked by lac operator sequences and works in any strain of E. coli. The PhoA promoter does not require expensive or metabolizable inducers, but auto-induces once the cells have depleted the phosphate from the media.

How does T7 work?

T7 RNA polymerase is a very active enzyme: it synthesizes RNA at a rate several times that of E. coli RNA polymerase and it terminates transcription less frequently; in fact, its transcription can circumnavigate a plasmid, resulting in RNA several times the plasmid length in size.

What is CAG promoter?

The CAG promoter is a strong synthetic promoter frequently used to drive high levels of gene expression in mammalian expression vectors. CAG promoter was constructed in the lab of Dr Jun-ichi Miyazaki from the following sequences: ( A) the promoter, the first exon and the first intron of chicken beta-actin gene,

Is CAG a strong promoter for recombinant protein expression in hek293f cells?

In conclusion, our data show that the CAG promoter is a strong promoter for recombinant protein expression in HEK293F cells. cytomegalovirus (CMV) enhancer fused to the chicken beta‐actin promoter

What is chicken beta actin (CAG) promoter?

^ Alexopoulou, AN; Couchman, JR; Whiteford, JR (2008). “The CMV early enhancer/chicken beta actin (CAG) promoter can be used to drive transgene expression during the differentiation of murine embryonic stem cells into vascular progenitors”.

Which promoter‐driven vector has the shortest transgene expression?

In this study, the CMV promoter was used in the control vector to evaluate the transgene expression levels from seven other promoter‐driven vectors. Of the eight promoters investigated here, the CAG enhancer was the shortest, followed by the mouse CMV and PGK promoters.
