4 . the result of ability to a - complement testified the protein pair we prepared was highly active for a - complementation Ea 、 ed蛋白的a一互补功能试验证实制备的ea 、 ed蛋白能二成功互补，形成具有高活性的卜半乳糖昔酶。
The results show that , ( 1 ) in different human tumor cells , n - acetylgalactosaminyltransferases gene expression levels differ from each other 这表明： (一)在不同肿瘤细胞中， n -乙酰氨基半乳糖转移酶基因的表达水平不一。
Dried milk , dried ice - mixes and processed cheese - determination of lactose content - enzymatic method utilizing the galactose moiety of the lactose 奶粉干冰混合物和加工的奶酪.测定乳糖含量.利用乳糖中半乳糖含量的酶催化方法
But the ppl researchers have succeeded in knocking out only one copy of the gene for the enzyme , called alpha 1 ， 3 galactosyl transferase 但是, ppl医疗公司的研究人员只是成功地去除了产生这种叫? 1 , 3半乳糖转移酶的基因的一个副本。
The a - complementation reaction of & - galactosidase ea and ed was also used in dna cloning , protein protein interactions monitoring and expressing immunoassays studying -半乳糖苷酶的ea 、 ed这种-互补性还被用于分子生物学、蛋白质相互作用的监控、表达免疫分析等方面的研究。
Objective to analyze the differences of n - acetylgalactosaminyltransferases gene expression profile in different human tumor cells with preliminarily made cdna microarrays 目的本研究初步创建了低密度基因芯片，并对人不同肿瘤细胞中的n -乙酰氨基半乳糖转移酶基因家族进行表达谱分析。
Saccharide : glucose , mannose , xylose and galactose and so on are included . this kind of amylose can improve human immunity , and acts on the prevention and cure of cancer and aids 糖类：包括葡萄糖、甘露糖、木糖、半乳糖等。这类多糖对提高人体免疫功能，对癌症和艾滋病的防治有一定作用。
Ability to a - complement of the ea / ed protein was determined by the addition of onpg western blot test with rabbit to e . coli p - galactosidase pcab as first antibody was used to verify the fusion proteins 以兔抗p半乳糖昔酶抗体做western blot以证实与gst融合表达的ea工d蛋白是p半乳糖昔酶的成分。实验结果1
