公式:
length of insert (bp)/length of vector (bp) x ng of vector = ng of insert needed for 1:1 insert:vector ratio
(插入片段长度 (bp) X 载体重量(ng) ) / 载体长度 (bp) = 插入片段:载体比例为1:1时所需的插入片段重量(ng)

'Telomere dynamics, chromosomal instability, and cellular viability were studied in serial passages of mouse embryonic stem (ES) cells in which the telomerase RNA (mTER) gene was deleted. These cells lack detectable telomerase activity, and their growth rate was reduced after more than 300 divisions and almost zero after 450 cell ... More
