Competent yeast cells can be stored at -80°C for up to one year without loss of transformation potential1. However, flash freezing in liquid N2 or in a -80° freezer is not recommended for competent yeast cells. Competent yeast cells need to undergo slow freezing like mammalian cells in a cryoprotectant. This can be carried out as follows:

The outcome of Li alloying based 2-D-LiZnSb transformation yielded the 2-D-ZnSb product, which did not return to its 3-D form. Song et al. showed that once formed, the layered 2-D-ZnSb was a stable.

Using yeast in log phase is only important if you need really high transformation efficiency (2 hybrid or library screening). For routine transformations we dilute yeast 1:5 and grow 2-3 hours before transforming (not quite log phase). Also, adding DMSO to about 10% in your transformation mix can improve efficiency about 5 fold.

Our polymeric carrier based transformation approach yielded 17,100 colonies of yeast transformants per 1 µg of DNA, while the standard electroporation protocol resulted in 1000 colonies, and chemical LiAc-based transformation yielded 8300 colonies .

The cell‐growth stage of yeast is an important factor in both cryopreservation and transformation. Yeast cells in the stationary phase generally become more resistant to cryoinjury and hypertonic stress than do those in the exponential phase (Morris et al., 1988; Lewis et al., 1993).

I am just starting my first attempts at yeast transformation in preparation for a Y2H screen. After two attempts withe Clontech Yeast.

potentially novel interactions. One reason why the Yeast Transformation System 2 yields more transformants (per µg of DNA) than many other commonly used methods is because it includes an uncommon but crucial incubation step: After the addition of DNA and treatment with DMSO, yeast cells are incubated in YPD Plus Liquid Medium—a
