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.

The carbonic anhydrases (or carbonate dehydratases) are classified as metalloenzyme for its zinc ion prosthetic group and form a family of enzymes that catalyze the rapid interconversion of carbon dioxide and water to bicarbonate and protons, a reversible reaction that takes part in maintaining acid-base balance in blood and other tissues. The carbonic anhydrasekl (CA) family consists of at least 11 enzymatically active members and a few inactive homologous proteins. Carbonic anhydrase protein (CA) VIII, which is a member of the CA gene family, has been shown to have no catalytic CA activity and its biological function is still unknown. Increased expression of CA-RP VIII was observed in 78% of colorectal carcinomas. It suggested that CA-RP VIII plays a role in the process of invasion in colorectal cancer.
