The shake flask is connected to the port terminus using aseptic techniques, and then the clamps are ... disconnected. At this point, the harvest port terminus must be covered up again with sterile cotton and ...

Expression and Purification of Recombinant Proteins That Have Native Amino Acid Sequence

... expressed protein. Because EK cleaves at the C terminus of its recognition target, which is also the N terminus of the inserted polypeptide sequence, cleavage ... cleavage of all sequences at the N terminus of the polypeptide of interest and produces ...

Efficient Cleavage of Fusion Proteins to Yield Native Amino Termini

... an efficient, sitespecific protease that cleaves at the carboxy terminus of its recognition target. Cleavage of fusion proteins that contain the ... to fuse the 5-amino-acid EK target site to the natural amino terminus of the JNK protein. The PCR product was inserted into the ...

RNA Interference and Gene Silencing: History and Overview

... active RISC then targets the homologous transcript by base pairing interactions and cleaves the mRNA ~12 nucleotides from the 3' terminus of the siRNA (3 , 18 , 27 , 29 ...

Sequence-Validated and Expression-Tested Human cDNA in a Dual Expression Vector

... and tandem consensus sequences for optimal translation initiation in both systems. The c-myc epitope and HIS6 purification tags at the carboxy terminus of the expressed protein allow proteins to be detected and purified, respectively. The tags can be separated from the protein encoded by the cDNA ...
