The cDNA sequence of human NAMPT was amplified by PCR from the pGex-6p-3-hNAMPT plasmid (kindly gifted from Dr Shui-qing YE, College of Missouri). The PCR items were digested and cloned into a pET21a+ vector using NdeI and XhoI restriction enzymes. A degree mutation was launched by the short transform website-directed https://capsaicin32109.mybuzzblog.com/6035223/xeruborbactam-can-be-fun-for-anyone
