ColE1 is a plasmid found in bacteria. Its name derives from the fact that it carries a gene for colicin E1 (the cea gene). It also codes for immunity from this product with the imm gene.

复制起点（replicon）是使用质粒时必须要考虑的一个基本元件，它显著影响着质粒拷贝数，一种复制起点不一定能在所有生物体中行使其功能，使用质粒时需要对复制起点进行选择。 01复 …

2023年8月3日 · The name ColE1 stands for the gene colicin E1. This plasmid is found in bacteria E. coli. It is a naturally occurring plasmid in bacteria. ColE1 plasmid belongs to the family of …

2024年8月22日 · ColE1质粒存在于大肠杆菌中，是细菌素家族成员，通过反义RNA控制复制。它是非接合质粒，无法自主传输。ColE1质粒常用于基因工程，其抗性基因被用于工业。大肠杆 …

ColE1 (大肠杆菌素),这个质粒的真身就是从大肠杆菌中发现的天然的质粒,是个原核质粒,所以它的ori只需要1个。而慢病毒、逆转录病毒属于RNA病毒,只有1个复制起点。

质粒的自主复制性（可扩增性）： 质粒能利用寄主细胞的DNA复制系统进行自主复制，并根据在每个细胞中的分子数（拷贝数）多寡，质粒可分为两大复制类型：严紧型复制控制的质粒1~3拷 …

ColE1 is the prototype of many closely related high-copy-number plasmids. Its replication control circuit has been investigated in great detail (for a review, see Eguchi et al., 1991) . ColE1 does …

ColE1载体价格4800元，ColE1载体质粒图谱 (Vector map)，载体序列 (Sequence)见下文，载体质粒抗性为Col E1imm，质粒大小为6.6 kb。 ColE1载体是质粒。

Analysis of plasmid ColE1, its naturally occurring relatives ColK and CloDF13, and a wide range of ColE1 derivatives containing either insertions or deletions of genetic material has allowed …

ColE1-like plasmids constitute the most popular vectors for recombinant protein expression. ColE1 plasmid replication is tightly controlled by an antisense RNA mechanism that is highly …
