This method was reported by Hanahan and Meselson (1980, 1983) and is primarily used to treat bacteria transformed by plasmid cDNA libraries. A mixture of transf
The purpose of sinister mutation testing is mainly for figuring out the molecular mechanisms of human hereditary diseases in order to effectively target these d
The nested deletion mutagenesis method, in which multiple oligonucleotides are progressively deleted from one or the other end of the target DNA, has been used
This protocol uses the nuclease BAL31 (purified from the marine bacterium Alteromonas espejiana BAL31) to produce unidirectional or bidirectional deletions in c
Tabor and Richardson in 1985 and Studier and Moffatt in 1986 proposed a new expression system utilizing the T7 phage promoter, using transcriptional signals obt
This method is suitable for rapid screening of immunodetectable fusion proteins against λgtll recombinant phage. However, under other conditions (e.g., optimiz
This protocol will discuss the factors affecting plasmid expression efficiency in the Troubleshooting and Optimization of Inducible Promoter Expression Proteins
The methods described in this section are only for the preparation of antisera containing relatively low-titer anti-E. coli antibodies. If the treated antiserum
The λ phage PL promoter is a potent promoter controlled by a temperature-sensitive repressor (cIts857), which can repress transcription of the PL promoter at l
There are three methods for detecting bound antibodies: radiochemical screening, colorimetric screening, and chemiluminescent screening, the advantages and disa
