半岛bd体育手机客户端 说明
一般描述
Recombinant DNA technology enables the insertion of specific short sequences into genes of interest. This can provide an ′affinity handles′ (tags) for the selective identification and purification of the recombinant protein.1-3 The addition of Bacterial Alkaline Phosphatase tag to a given gene, creates stable fusion product that does not appear to interfere with the bioactivity of the protein, or with the biodistribution of the Bacterial Alkaline Phosphatase tagged product. Bacterial Alkaline Phosphatase (also known as PhoA, EC 3.1.3.1) is a app. ～50 kDa protein, derived fromE.coli.
特异性
Monoclonal Anti-BAP antibody specifically recognizes Bacterial Alkaline Phosphatase-tagged fusion protein.
应用
Monoclonal Anti-Bacterial Alkaline Phosphatase antibody may be useful in various immunotechniques, to identify the expression of Bacterial Alkaline Phosphatase fusion protein in situ or by immunoblotting, in bacteria, bacterial lysates, and cells or tissues transfected with Bacterial Alkaline Phosphatase fusion protein expressing vectors. In addition, expression system that exploits the Bacterial Alkaline Phosphatase signal sequence in order to translocate a target protein to the periplasm, may be used to evaluate how changes in the composition and sequence of amino acids near the Bacterial Alkaline Phosphatase-target protein junction influence the periplasmic accumulation of the target recombinant protein.8
生化/生理作用
Alkaline phosphatase appears to require export to the periplasm for its enzymatic activity.4 Fusions of the secreted alkaline phosphatase to an integral cytoplasmic membrane protein ofE.colishows different activities depending on where is it fused with the membrane protein.5 Fusions to positions in or near the periplasmic (extracellular) domain lead to high alkaline phosphatase activity, whereas those located to positions in the cytoplasmic domain reside in low activity. Consequently, analysis of alkaline phosphatase fusions to membrane proteins of unknown structure are generally useful in determining their membrane topologies.4 Expression of enzymatically active protein fusions inE.colicould facilitate the analysis of proteins and even replace some reagents frequently used in immunology such as chemically-produced antibody-enzyme conugates.6,7
