不同電擊管的電壓參數(shù)需要換算，時間相同。以20ul電擊管參數(shù)為基準，100ul比20ul約上調10V；200ul是20ul的約2.4倍；1000ul是20ul約2.5倍；120ul的是20ul的約1.4倍，600ul的是20ul的約1.6倍。下面是轉換示例：
20ul：500V
100ul: 510V （20ul電壓+10V）
200ul：1200V （20ul電壓的2.4倍）
1000ul：1250V （20ul電壓的2.5倍）
120ul：700V （20ul電壓的1.4倍）
600ul：800V （20ul電壓的1.6倍）
*部分單核細胞相關的細胞系，電轉質粒后幾乎所有電轉成功的細胞會死亡，而電轉mRNA，siRNA和Cas9 RNP沒關系。Celetrix公司專門開發(fā)了試劑盒可以幫助單核細胞類的細胞系進行質粒電轉，目前驗證過THP-1和U937這兩種細胞系電轉效果非常好，而Molm-13和Sup-M2細胞電轉質粒細胞死亡問題還沒有解決。

*Many monocyte or macrophage related cell lines such as THP-1, U937, HL-60 and Molm13 will die out within two to three days after plasmid electroporation. These cells have no problem with mRNA, siRNA and Cas9 RNP electroporation. The efficiency would be nearly 100% and cell survival is not affected. Celetrix has developed the THP-1 Helper Kit for plasmid electroporation of monocytic cell lines. A significant portion of THP-1 and U937 cells can survive and grow with the helper kit, enabling easy generation of stable cell lines. Our THP-1 Helper Kit does not help cell lines such as Molm13 and SUP-M2 with plasmid electroporation and we are actively researching the solutions.
