GeneArt™ pYES1L Vector with Sapphire™ Technology

We would recommend trying to re-streak the colony on a fresh plate and repeat colony PCR. Do not break open the yeast cells with the beads supplied with the kit; the beads are for transformation into E. coli. Additionally, use less than 0.5 µL of diluted yeast lysate in a 50 µL PCR reaction.

Ensure that yeast transformations are incubated at 30 degrees C for 3 days for proper colony formation.

Please review the following suggestions:
– Perform transformation exactly as described in protocol.
– Do not freeze-thaw or vortex MaV203 yeast competent cells.
– Use CSM-Trp agar plates for the transformation.
– For best results, use fresh DMSO from an unopened bottle. You may use DMSO stored at -20 degrees C.

Yes, you should be able to adapt your E. coli vector into a yeast-compatible cloning vector using the GeneArt High-Order Vector Conversion Cassette (Cat. No. A13291) for use with the GeneArt High-Order Genetic Assembly System with the following provisions:
– Start by using the DNA Oligo Designer web tool, and verify that your vector and the GeneArt High-Order Vector Conversion Cassette do not share internal homology to prevent potential re-arrangements when using your adapted vector with the GeneArt High-Order Genetic Assembly System.
– Use a vector with a single- or low-copy-number origin for a final construct of >15 kb, if the final plasmid construct will be transferred into E. coli. Usually, low-copy-number E. coli vectors have significantly higher capacity than high-copy number vectors.
– Avoid chloramphenicol selection markers on the custom vector since this is the marker on the cassette.
– After ligation (1:10 vector: insert ratio recommended), transform competent E. coli cells with the ligation mixture and plate on double selection LB plates (chloramphenicol plus the antibiotic marker on your custom vector backbone).To linearize your yeast-adapted cloning vector for multi-fragment assembly, a double-digestion is required to avoid background caused by residual palindromic end sequences resulting from a single enzyme digestion.

Stitching oligonucleotides used for insertion editing must have a 30-nucleotide overlap with each adjacent fragment in addition to the insertion bases (for a total length of up to 80-mer, including up to 20 insertion bases). See manual for diagram. Note: This applies for a 2-fragment assembly and the insertion applies only to the internal junction. Use a 40-bp overlap (i.e., an 80-mer oligonucleotide) for the remaining seamless junctions.


Stitching oligonucleotides used for deletion editing must have a 40-nucleotide overlap with each adjacent fragment, annealing up to 6 nucleotides from the junction into each fragment, thus leaving up to 6 bp at the end of each fragment to be deleted during transformation-associated recombination. See manual for diagram. Note: This applies for a 2-fragment assembly and the deletion applies only to the internal junction. Use a 40-bp overlap (i.e., an 80-mer oligonucleotide) for the remaining seamless junctions.
