COVID-19 is currently destroying hundreds of thousands of lives around the world. Widespread testing for this virus is necessary to control its spread, but in many places, conducting tests costs too much money because of the reagent cost. We have collected expression plasmids for the most expensive test components, the enzymes. With these expression plasmids, users can produce the enzymes needed to do testing locally much cheaper than it would cost to purchase or import them, which we hope will allow for more COVID-19 tests.

What is it:
This is a collection of 5 different protein-coding genes in expression vectors, including 2 reverse transcriptases (HIV-RT and MMLV-RT), two DNA polymerases (Taq and Bst-LF), and one RNA inhibitor. All vectors, except HIV-RT, are ampicillin resistant, with HIV-RT being kanamycin resistant. The RNAse inhibitor plasmid and the Taq polymerase plasmid both use the tac promoter, while the HIV-RT, MMLV-RT, and Bst-LF plasmids use the T7 promoter.

Shipped as purified and dried down DNA stained with Cresol Red in one 96-well plate. Each well contains approximately 50 ng of DNA. Cresol Red will not impact plasmid transformation.

Plate map can be found here.

What can it be used for:
These enzymes can generally be used for reverse transcription and PCR or LAMP amplification. Any protocol that requires any of those 3 reactions can use the enzymes expressed in these vectors.

Thanks to:
These materials were created by the Dickinson lab at UC Chicago, Alex Brown at National Jewish Health, John Schloendorn at Gene And Cell Technology, and the Open Bioeconomy Lab at Cambridge University.

Where I can find more information:

Here are the genbank format files for each detection enzyme expression vector. You will need the free SnapGene® viewer or other program.
