Fold-change分析
Webマイクロアレイによる 遺伝 子発現解析では,一般的に対照となるコントロールのシグナル値(蛍光強度)で測定対象のシグナル値を割った相対比を fold-change (倍率変化)として評価に用いる. fold-change は処置群とコントロール群のアレイのシグナル値を ... Webfold change仅仅靠最终值与初始值的比率计算即可得到。 2、例如,若初始值为A,最终值为B,则fold change为B/A。 3、再举一个例子,从80变到20,则fold change为0.25,反之,20变到80的fold change为4。一些开发值将小于1的fold change替换为对应的负数。 4、例如,从80变到20时 ...
