pMD18-T Simple Vector Information

pMD18-T Simple Vector is a high-efficiency TA cloning vector constructed from pUC18, of which the initial multiple cloning sites (MCS) were destroyed. Thus the cDNA should be amplified by PCR with primers containing a restriction site for subclone. Competent cells appropriate for pUC18 are also appropriated for the Vector, e.g. JM109, DH5α, TOP10. The pMD18-T Simple Vector is 2.6kb in size. Selection of the plasmid in E. coli is conferred by the ampicillin resistance gene. The coding sequence was inserted by TA cloning at site 425.

pMD18-T Simple Usage Suggestion

The coding sequence can be amplified by PCR with M13-47 and RV-M primers.

Cathepsin E Protein (CTSE Protein) is a member of the peptidase C1 family that is a gastric aspartic protease that functions as a disulfide-linked homodimer. Cathepsin E Protein (CTSE Protein) is predominantly present in the cells of immune system and is frequently implicated in antigen processing via the MHC classⅡ pathway which however does not appear to be involved in the digestion of dietary protein. The protein has a specificity similar to that of pepsin and pepsin. Cathepsin E Protein (CTSE Protein) is found in highest concentration in the surface of epithelial mucus-producing cells of the stomach and also been found in more than half of the gastric cancers. It appears, therefore, to be an oncofetal antigen.
