SV40（with Enhancer） is a widely used strong promoter.

SV40 is an abbreviation for Simian Virus 40, a polyomavirus that is found in both monkeys and humans. SV40 promoter, which is one of the earliest virus promoter being found by biologists, can improve the gene expression level of many host cells.[1] Similar to 35S promoter, SV40 has a relatively small genetic structure and high expression driving ability.[2-3] As a strong promoter being widely used in genetic engineering,[4] SV40 has a close affinity with RNA polymerase and can direct the massive synthesizing of mRNA.

In our project, we construct SV40 and Renilla luciferase(Rlu) in the same plasmid. By detecting the expression of Rlu, we are able to tell the working efficiency of our system.

SV40 is 419bp in length. Fig. 2 shows the DNA sequence of SV40 is successfully amplified by PCR from psi-Check2 vector. In this electrophoretogram, Track 1,2 and 3 are all SV40 that are amplified. We can see the brightness of SV40 PCR product is rather high compared with DNA Marker, which indicates that the PCR product of SV40 is in a high concerntration.

Design Notes

We designed the following primers and amplified SV40 promoter from the vector psi-Check2:

By incorporating these primers into hUPII promoter, the promoter is flanked by the iGEM prefix and suffix after amplification.

Source

SV40 promoter with enhancer was achieved from Shenzhen Second People's Hospital.
