What is gTOW6000?

  • gTOW6000 is a plasmid collection covering the whole genes (about 5,700) in Saccharomyces cerevisiae. We constructed those plasmids to analyze the upper limit of copy number for each gene by gTOW method.
  • Each gene has been cloned into the plasmid vector pTOWug2-836 and transformed into S. cerevisiae BY4741 strain for long-term storage.
  • We store two clones per each gene. The gene coverage is >90% and can be browsed in gTOW6000 Datasheet.
  • The insert size of each gene has been checked by PCR (NOT by restriction digest and/or sequencing).

To whom wish to use our resource

  • Individual information for each gene can be found in gTOW6000 Datasheet.
  • gTOW6000 is available via NBRP-yeast.
  • Please mote:
    • NBRP manages each gene by the location on a plate e.g. BYgTOW00A01 means plate #0, position #A01.
    • There may be several clones lost during storage process, even though it certainly exists in the datasheet. Inquire NBRP for details.
    • There may be some genes successfully cloned after the datasheet was made (so it appears negative in the datasheet). Contact Hisao Moriya for details.
  • Contact us if you would like to use primers or gene products in the gTOW6000 project (we may offer a collaborative studies).

Schemes for constructing gTOW6000


1. Design primers which cover promotor and terminator regions of individual gene on genome
2. Amplify target gene by PCR
3-4. Clone PCR product into plasmid pTOWug2-836 in S. cerevisiae BY4741 strain by Gap-Repair Cloning, and transform cells on 96-well plate
5. Pick up two colonies per each gene
6. Static culture cells in two different liquid media
7. Extract DNA individually from both media
8. Verify insert size by PCR
9. Glean unsuccessful genes in case the verification at step 8 fails to confirm expected size of insert; re-design primers, recover colonies and repeat steps 2-6

Cells containing plasmid with expected size (verified by PCR) have been considered to be gTOW6000 clones and stored.
