詳細
An intermediate strength constitutive bacterial promoter that allows for protein expression in E. coli. This promoter was derived by modification of the RecA E. coli promoter to remove the LexA repressor site followed by random mutagenesis to create a pael of promoter. This promoter was found to demonstrate intermediate expression levels when gene expression was analysed during E. coli log phase growth in shaking culture. The promoter in this plasmid is called OXB11 because it demonstrates roughly intermediate levels of expression between OXB1 and OXB20 which are the promoters showing the lowest and highest levels of promoter activity in this product range respectively.
Promoter Expression Level: This plasmid contains a medium strength constitutive E. coli promoter that was derived from the RecA promoter by random mutagenesis. It is part of our constitutive bacterial promoter range. This promoter (OXB11) shows the intermediate levels of expression in the range with OXB1 showing the lowest level and OXB20 showing the highest level of expression. They require no inducing agent for expression.

アプリケーション
Cloning in a gene: This plasmid has been designed to be compatible with a range of cloning techniques. The multiple cloning site contains a range of standard commonly used restriction sites for cloning. Using these sites genes can be inserted using standard cloning methods with DNA ligase. Other methods such as ligase independent cloning (LIC) Gibson Assembly InFusionHD or Seamless GeneArt can also be used and because all of our plasmids are based on the same backbone the same method can be used for cloning into all of our catalogue vectors.
Multiple cloning site notes: There are a few important sites within the MCS. These include the NcoI site the XbaI site and the BsgI and BseRI sites. The NcoI site contains a start codon that is immediately downstream of both a Kozak and Shine-Dalgarno ribosomal binding site. These allow for optimal positioning of genes when the start codon is placed in this location. If this is not required and you wish to use a downstream site for gene cloning you can remove the NcoI site by cleaving the plasmid with KpnI.
The XbaI site contains a stop codon. This stop codon is positioned in a specific position in relation to the BsgI and BseRI sites that are immediately downstream. When either BseRI or BsgI cleave the plasmid they produce a TA overhang from the stop codon in the XbaI site that is compatible with all of our peptide tag plasmids cut with the same sites. BseRI and BsgI sites are non-palindromic and cleave a defined number of bases away from their binding site.
Whenever we clone a gene into our multiple cloning site we always position the start and stop codon in the same positions in the MCS. If the start and ends of the genes are not compatible with NcoI and XbaI we extend the sequence to the nearest external sites but keep the start and stop codons locations consistent.

The Notch3 signaling pathway is thought to play a critical role in cancer development, as evidenced by the Notch3 amplification and rearrangement observed in human cancers. However, the molecular mechanism by which Notch3 signaling contributes to tumorigenesis is largely unknown.

Recycling of signaling proteins is a common phenomenon in diverse signaling pathways. In photoreceptors of Drosophila, light absorption by rhodopsin triggers a phospholipase Cβ-mediated opening of the ion channels transient receptor potential (TRP) and TRP-like (TRPL) and generates the visual
