摘要: We have developed a method for preparing high-quality total RNA from Ca-alginate-encapsulated Saccharomyces cerevisiae that is suitable microarray analysis. Encapsulated cells were harvested immobilized cell reactors and flash-frozen in liquid nitrogen. Following low-temperature mechanical disruption, freed Ca-alginate by reverse ionotropic gelation purified centrifugation, then was extracted using hot acid phenol. The yield quality of the consistently high; free contaminating alginate, analysis it performed as well isolated planktonic cells.
