• 使用CopyControl™克隆系统构建具有可抗污染噬菌体T1和T5的克隆的诱导拷贝数基因组文库。
• Construction of inducible-copy-number genomic libraries using the CopyControl™ Cloning System, with clones that are resistant to contaminating phage T1 ａnd T5.

噬菌体抗T1的TransforMax™EPI300™-T1 ^R 大肠杆菌  具有功能强大的TransforMax EPI300™ 大肠杆菌  感受态细胞的所有优点，  此外还具有对噬菌体T1和T5（tonA  基因型）的抗性。一旦引入实验室环境，噬菌体T1就会迅速裂解   克隆应用中常用的大肠杆菌菌株，并导致大量的实验室停机时间和有价值的克隆丢失。噬菌体T1特别难以从实验室中清除，并且可以休眠多年。所述  TONA  基因型保护噬菌体TransforMax EC100-T1耐T1- ^ř  通过噬菌体T1免受攻击细胞和有价值的克隆。

Phage T1-Resistant TransforMax™ EPI300™-T1^R E. coli have all the benefits of the highly versatile TransforMax EPI300™ E. coli competent cells with the addition of being resistant to bacteriophages T1 ａnd T5 (tonA genotype). Once introduced into the lab environment, bacteriophage T1 rapidly lyses E. coli strains that are commonly used in cloning applications ａnd results in significant lab downtime ａnd the loss of valuable clones. Bacteriophage T1 is particularly difficult to eliminate from the lab ａnd can lay dormant for many years. The tonA genotype protects the phage T1-resistant TransforMax EC100-T1^R cells ａnd valuable clones from attack by bacteriophage T1.

与标准TransforMax EPI300  大肠杆菌一样，该菌株经过特殊设计，可与EPICENTRE的CopyControl™克隆系统一起使用。*细胞含有可诱导的突变  trfA  基因，其基因产物是从CopyControl上的ori V 起始复制所需  的pCC1™载体或使用EZ-Tn5™< ori V / KAN-2>插入套件通过CopyControl功能改造的克隆。该过程使TransforMax EPI300-T1 ^R.  coli  能够将CopyControl载体保持为单拷贝，直到在DNA纯化前立即进行诱导。

Like the standard TransforMax EPI300 E. coli, this strain has been specially engineered for use with EPICENTRE＇s CopyControl™ Cloning Systems.* The cells contain an inducible mutant trfA gene whose gene product is required for initiation of replication from the oriV contained on the CopyControl pCC1™ Vectors or on clones that have been retrofitted with CopyControl capability using the EZ-Tn5™<oriV/KAN-2> Insertion Kit. This process allows TransforMax EPI300-T1^R E. coli to maintain CopyControl vectors at single copy until induction occurs immediately before DNA purification.
