Vectors for expression and secretion of FLAG epitope-tagged proteins in mammalian cells.
نویسندگان
چکیده
The FLAG peptide, AspTyrLysAspAspAspAspLys, has been used as an epitope tag in a variety of cell types. The modification of the cytomegalovirus (CMV) promoter containing vector, pCMV5, to create two transient expression vectors designed for secretion and intracellular expression of FLAG-fusion proteins in mammalian cells is described. As a functional test, the bacterial alkaline phosphatase gene was cloned into both vectors, and anti-FLAG monoclonal antibodies were used for detection of FLAG epitope-tagged bacterial alkaline phosphatase in mammalian cells. In addition, secreted bacterial alkaline phosphatase was purified from the extracellular medium by anti-FLAG affinity chromatography.

Epitope tagging is a method of expressing proteins whereby an epitope for a specific monoclonal antibody is fused to a target protein using recombinant DNA techniques. The aim of this study was to sub-clone the peroxisomal protein (PEP) cDNA into a mammalian expression vector leading to the formation of a chimeric PEP-cDNA containing the FLAG epitope. The FLAG-PEP recombinant cDNA was construc...

Inefficient secretion of the human coagulation factor (hFVIII) in mammalian expression systems is one ofthe main causes of the hFVIII low expression level, attributed to its interaction with a chaperone known asBiP/GRP78. In order to improve secretion efficiency of the hFVIII, based on the higher secretion level of theporcine FVIII and analysis of the hFVIII A110 region, that ...

Expression and purification of recombinant proteins are fundamental techniques in molecular biology. Many different cell systems ranging from bacteria to mammalian cell lines are commonly used. One of the most widely used systems is the baculovirus expression system. An alternative for large-scale production of eukaryotic proteins are stably transfected Schneider Drosophila line 2 cells (Catalo...

Gateway cloning technology facilitates high-throughput cloning of target sequences by making use of the bacteriophage lambda site-specific recombination system. Target sequences are first captured in a commercially available "entry vector" and are then recombined into various "destination vectors" for expression in different experimental organisms. Gateway technology has been embraced by a numb...

BACKGROUND In vivo overexpression of proteins is a powerful approach to study their biological function, generate disease models or evaluate gene therapy approaches. In order to investigate an exogenously expressed protein, specific and sensitive detection is essential. Unfortunately, antibodies that allow histological detection of the protein of interest are not always readily available. The u...
