亲和常数 meaning in English
affinity constant
Examples
- The determination of human thymidine kinase ( htk ) in human serum , which is a key indicator of cancers can give information for the diagnosis and treatment of the malign diseases . the protein a layer was first self - assembled onto the gold electrode surfaces of quartz crystals , the monoclonal antibodies were then orientedly immobilized through the specific binding between the fc terminals of the antibodies and the self - assembled protein a . with this sensor , the affinity constant of antigen - antibody binding was estimated to be 1 . 85 106 l / mol according to the scatchard ’ s plotting method , which proved the high bioactivity of antibody . finally , an amplified piezoelectric immunosensor was designed to determine the htk in
实验中将蛋白a吸附于镀金压电石英晶体电极表面,用于定向固定htk单克隆抗体,成功研制了检测htk的压电石英晶体传感器,并基于标准scatchard绘图法,计算出免疫反应的亲和常数为1 . 85 106l / mol ,证明该单克隆抗体具有较高的免疫活性;同时基于酶催化沉淀技术,设计了的检测htk的质量放大压电石英晶体传感器,该传感器可在0 . 1 - 10ng范围内对htk进行定量检测,应用此传感器成功地对5种癌症病人血清中htk的浓度进行了测定,实验结果为癌症的临床诊断与治疗提供了参考。 - Two types of 11 - hsds were identified in vertebrates : whereas 11 - hsd2 , a nad - dependent oxidase , functions exclusively to convert biologically active gc into its inert form , attenuating gc ' s action , 11b - hsd1 was shown to act as a predominant nadp - dependent reductase in tact cells , thus amplifying gc ' s action
在体内，至少存在两种亚型的11 - hsd 。 11 - hsd2主要分布于盐皮质激素( mineralocorticoidhormone , mc )的靶器官，表现为单一的氧化酶活性，与作用底物的亲和力较高，亲和常数在nm水平。 - With anti - t - jgy establishing a radioimmunoassay , the quality of anti - t4 igy was appraised : litres was 1 : 25 00 , permitting rang of litres in the ria was from 1 : 2500 to 1 : 5000 ; the degree of cross reactivities with ta was 1 . 28 % ; affinity constants was 2 . 13 x 109l / mol
本文应用蛋黄正丁醇去脂获得的抗t4 igy建立了放免检测方法，对抗t4igy的质量进行鉴定：抗体滴度为1 ： 2500 ，工作浓度在1 ： 2500至1 ： 5000范围内；与t3的交叉反应为1 28 ；亲和常数为2 13x109l m 。
