The doublets and cellaggregates did seriously influence the measurement of G0/G1 and M2 + G2 phase in fixed cells on solid tissue cells easily to produce doublets of DNA DDM could remove influence of doublets in DNA measurement.

• DNA测量粘连细胞及细胞团严重影响G0/G1及M2+G2期测量，在固定细胞、实体病细胞等易产生粘连情况，细胞样品DNA测量中应用DDM除去粘连细胞的影响。
