Determination of the content of 1 - cyanoguanidine of the metformin hydrochloride sustained - release tablets by hplc
法測定鹽酸二甲雙胍緩釋片中雜質雙氰胺含量Extraction and determination of xanthochrous nilgheriensis teng polysaccharide and its antioxidation property
高效液相色譜法測定甲氰咪胍氯化鈉注射液的含量The total rna was purified from the germ in the liquid by the guanidine isothiocyantehod method, then the total rna digested by dnase that had not rnase was used for rt - pcr. i change the magnesium ion dencity in the pcr system in order to optimize the pcr condition. at the end i selected the magnesium ion density as 1. 25 mm. the production of rt - pcr was inserted directionally into pgem ? z ( ampr ). the pgem ? z ( ampr ) was used to transform e coli jm109. i got a positive clone through culling and identificatin. the dna sequence inserted into pgem ? z ( ampr ) was sequenced and blasted with the cdna sequence of the # - mannanase mature peptide that got from genbank
分取誘導培養液中的菌體，用異硫氰酸胍法提取總rna ，總rna再經無rna酶的dna酶處理後用于rt ? pcr 。在pcr擴增目的基因時，通過優選擴增體系，使鎂離子濃度為1 . 25mm時rt ? pcr可順利地獲得目的基因，並能定向克隆到載體pgem ? 3z （ amp ~ r ）中。用克隆載體轉化宿主大腸桿菌jm109 ，通過篩選獲取陽性克隆子，對陽性克隆子進行酶切與pcr鑒定，並對載體中插入的目的基因進行測序。
