载体简介

FLAG和3XFLAG:

A Proven System for Detection and Purification of Proteins The FLAG Expression System is an established way to express, purify and detect recombinant fusion proteins. FLAG and 3xFLAG have proven utility in numerous applications such as Western blotting, immunocytochemistry, immunoprecipitation, flow cytometry, protein purification, and in the study of protein-protein interactions, cell ultrastructure and protein localization. These small hydrophilic tags facilitate superior detection and purification of recombinant fusion proteins when using our highly specific and sensitive ANTI-FLAG antibodies. Ideal Epitope Tags: Small, Hydrophilic and Cleavable The FLAG expression system utilizes a short, hydrophilic 8-amino acid peptide that is fused to the recombinant protein of interest. Because of its hydrophilic nature, the FLAG peptide is likely to be located on the surface of the fusion protein. As a result, the FLAG peptide is easily accessible for cleavage by enterokinase (Ek) and for detection with antibodies. In addition, because of the small size of the FLAG peptide tag, it is not likely to obscure other epitopes, domains, or alter function, secretion, or transport of the fusion protein. The 3xFLAG system is an improvement upon the original system by fusing 3 tandem FLAG epitopes (22 amino acids). Detection of fusion proteins containing 3xFLAG is enhanced up to 200 times more than any other system. Like the original FLAG tag, 3xFLAG is hydrophilic, contains an Ek cleavage site, and is relatively small. Therefore, the risk of altering protein function, blocking other epitopes or decreasing solubility is minimized. 

载体简介:

The p3XFLAG-CMV-7.1 Expression Vector is a 4.7 kb derivative of pCMV5 used to establish transient intracellular expression of N-terminal 3XFLAG fusion proteins in mammalian cells. The vector encodes three adjacent FLAG epitopes (Asp-Tyr-Lys-Xaa-Xaa-Asp) upstream of the multiple cloning region. This results in increased detection sensitivity using ANTI-FLAG M2 antibody. The third FLAG epitope includes the enterokinase recognition sequence, allowing cleavage of the 3XFLAG peptide from the purified fusion protein.

The p3XFLAG-CMV-7.1 Expression Vector is a shuttle vector for E. coli and mammalian cells. Efficiency of replication is optimal when using an SV40 T antigenexpressing host.

The p3XFLAG-CMV-7-BAP Control Plasmid is a 6.2 kb derivative of pCMV5 used for transient intracellular expression of N-terminal 3XFLAG bacterial alkaline phosphatase fusion protein in mammalian cells. The vector encodes three adjacent FLAG epitopes (Asp-Tyr-Lys-Xaa-Xaa-Asp) upstream of the multiple cloning region. The third FLAG epitope includes the enterokinase recognition sequence, allowing cleavage of the 3XFLAG peptide from the purified fusion protein.

Principle
The promoter-regulatory region of the human cytomegalovirus drives transcription of FLAG-fusion constructs.
