摘要

We describe here a simple method for analyzing the stability of recombinant yeast. The mouse salivary α-amylase gene was used in this system as a marker since the stability of recombinant yeast can be detected easily by a halo zone-forming assay on starch-supplemented plates. We used this method to evaluate the stability of recombinant yeast harbouring a 2μ directed episomal plasmid and of yeast harbouring the r-DNA directed integrative vector. Our results demonstrated clearly that the α-amylase gene was a convenient and reliable marker for evaluating the stability of recombinant yeasts in long-term cultivation.
