Directional and direct cloning strategy for high-throughput generation of recombinant baculoviruses.
The baculovirus expression vector system (BEVS) has become one of the most widely used systems for routine protein expression. We have developed an improved strategy to clone foreign genes directionally and directly into the baculovirus genome vector via a one-step procedure to generate recombinant viruses in a week. In this work, we constructed a host strain Escherichia coli DH10BacHB1.1, whic...
Starting from its translation initiation site, the Streptomyces lividans xylanase A signal peptide consists of 41 amino acids. This signal peptide was deleted and successively replaced with one of six signal peptides from other enzymes secreted by S. lividans and by a signal peptide from the outer membrane protein (LamB) of Escherichia coli. Deletion of the xylanase A signal peptide or modifica...
A strategy for the unambiguous identification and selective quantification of xanthan gum and locust bean gum (LBG) in gelled food concentrates is presented. DNA detection by polymerase chain reaction (PCR) showed to be a fast, sensitive, and selective method that can be used as a first screening tool in intact gelled food concentrates. An efficient isolation procedure is described removing com...
