目的：克隆长双歧杆菌ncc 2705株果糖结合蛋白bl 0033的基因，利用大肠杆菌表达GST - BL 0033融合蛋白并纯化。
Objective: to clone the gene of fructose binding protein BL0033 from Bifidobacterium longum NCC2705, and express and purify fusion protein GST-BL0033 in e.
另有两株为517和518、526和517位双位点突变，因为芯片上未点517位突变的探针，所以只检测到518和526位的突变，该突变与测序结果完全一致。
Because the probe of 517 rifampin-resistant did not be dotted on the gene chip, only sites of 518 and 526 mutations were detected, which were consistent with the results of DNA sequencing.
