DNA ReplicationPlasmidsThe direct visualization of plasmid DNA inside Escherichia coli cells is demonstrated using phase-fluorescence microscopy of DAPI (4',6-diamidino-2-phenylindole)-stained bacteria. Small as well as large plasmids could be detected, both in minicells and in cells of larger size...
Bacterial plasmids may often reach a copy number larger than 1000 per cell, corresponding to a total amount of DNA that may exceed the amount of DNA within the bacterial chromosome. This observation highlights the problem of cellular accommodation of large amounts of closed-circular nucleic acids,...
G+ Bacteria Plasmid DNAOUT 产品及特点 本试剂盒用于革兰氏阳性(G+)细菌小量制备质粒 DNA。本产品基于改良后的碱变性法,首先菌体经溶菌酶破壁,然后菌体经碱裂解、高盐、低 pH 处理,质粒可从菌体中释放出来,并特异、高效地被离心吸附柱吸附。通过清洗液的洗涤可去除杂质,在低盐、高pH 条件下洗脱,最后得到纯...

A plasmid miniprep is a molecular biology technique used to extract and purify small amounts of plasmid DNA from bacterial cells. Plasmids are circular DNA molecules found in bacteria, and the miniprep process aims to isolate the plasmid DNA for further analysis ...

A multifunctional magnetic nanoparticle (MNP)-assisted bioseparation method was developed to isolate plasmid DNA (pDNA) from Escherichia coli culture. Using the pH-sensitive carboxyl-modified magnetic nanoparticles, both cell capture and the subsequent removal of genomic DNA/protein complex after lysis ca...
Naked plasmid DNA is an attractive nonviral gene vector because of its inherent simplicity and because it is easily produced in bacteria and manipulated using standard recombinant DNA techniques. It shows very little dissemination and transfection at distant sites following delivery and can be re...
Transfection-grade plasmid isolation kits are specifically designed for scientists who need to extract plasmid DNA (pDNA) with minimal levels of endotoxins from bacterial cultures. During the plasmid purification process, large amounts of endotoxins are released from lysed bacteria, which ...
