Specifications

DescriptionThe EGY48 strain is a strain used for the LexA system yeast two-hybrid experiment developed by Clontech, MATα type, which can be directly transformed into a plasmid for protein interaction verification or library screening test
Gene TypesMATα, ura3, his3, trp1, LexAop (x6)-LEU2
Size100 µL/vial
QC resultTransformation efficiency of pGBKT7 plasmid detection:>104 cfu/μg DNA.
Note1. Competent cells should be thawed on ice as much as possible.
2. Transforming high concentrations of plasmids can correspondingly reduce the amount of bacteria that are ultimately used for plating.
3. The amount of plasmids can be increased when 2-3 plasmids are transformed at the same time.
4. The EGY48 yeast strain is sensitive to high temperature, and the suitable growth temperature is 27-30°C; above 31°C, the growth rate and transformation efficiency decrease exponentially.
5. Powdery colony is not contamination, it is a common phenomenon in yeast cell growth. When the cells were cultured on the plate for a few days, the Adenine on the plate was consumed by the yeast, and the yeast tried to synthesize Adenine for use through its own metabolic pathway. However, the ADE2 gene of some strains was destroyed, and the Adenine synthesis pathway was blocked; The genes 5, 6, 7, and 8 are all normal, so the intermediate product P-ribosylamino imidazole (AIR) accumulates in the cells and turns the colonies pink.
6. The growth rate of yeast in the defective medium is slower than that of the YPDA medium. The more defective components in the medium, the slower the growth. Take transformation plating as an example: apply YPDA plate at 29°C for 48 h to see clones with a diameter of 1 mm; Coat SD single-deficiency plates at 29°C for 48-60 h to see clones with a diameter of 1 mm; coat SD double-deficient plates at 29°C for 60-80 h to show colonies with a diameter of 1 mm; coat SD triple-deficient or quad-deficient plates at 29°C, 80-90 h of culture, 1 mm diameter clones can be seen.
