操作步骤【见下图】:
1、感受态细胞制备
30℃,于10ml YPD肉汤培养酵母菌直至中数量级(~5 x 106-2 x107 cells/ml 或OD600= 0.8-1.0)。以下步骤室温进行。
1-1,500 x g离心细胞4min,吸掉上清液;
1-2,加入10ml EZ1溶液清洗沉淀。重新离心沉淀细胞,吸掉上清液;
1-3,加入1ml EZ2溶液重悬沉淀细胞。
此时获得的感受态细胞即可直接用于转化或冻存备用(≤ -70°C)。注意需缓慢冻存细胞,不可使用液氮瞬间冻存细胞。
2、转化
以下步骤适用于新鲜制备和冻存(室温融化)的酵母感受态细胞。
2-1,取50µl感受态细胞与0.2-1µg DNA(体积少于5µl)混合;加入500µl EZ3溶液,完全混合;
2-2,30°C孵育45min,孵育过程中用手指轻弹或低速涡旋(如果适用于转化DNA)2-3次让其混匀;
2-3,从上面转化混合液中取50-150µl到适当平板上,没有必要沉淀或清洗细胞。、
2-4,30°C孵育平板2-4天使得转化子生长。

HIGHLIGHTS
- Fast: Yeast cells with high transformation efficiencies can be prepared in under 10 minutes.
- Simple: Easy method to transform with single or multiple plasmids in ≤ 1 hour with carrier DNA.
- Versatile: Can be used with S. cerevisiae, as well as other fungi, including C. albicans, S. pombe, and P. pastoris. Compatible with both circular and linear DNA.
DESCRIPTION
The Frozen-EZ Yeast Transformation II Kit is designed to make yeast transformations and library screening easier and more efficient than currently available methods. The yeast cells prepared with the Frozen-EZ Yeast Transformation II Kit can be used immediately for transformation or can be stored (i.e., ≤ -70°C) for use at a later time. Yeast prepared with this kit can be transformed with both circular and linear DNAs. Also, the Frozen-EZ Yeast Transformation II Kit can be used with other fungi including C. albicans, S. pombe, and P. pastors.
