Cloning of plasma membrane H-ATPase gene in Populus euphratica Oliv.     

Ning De-juan Hou Pei-chen Hu Zan-min Shen Xin Chen Shao-liang College of Biological Sciences  Biotechnology  Beijing Forestry University  Beijing  P. R. China Institute of Genetics  Developmental Biology  Chinese Academy of Sciences  Beijing  P. R. China 《中国林学(英文版)》2006,8(4):15-19

For this paper, the plasma membrane (PM) H -ATPase gene has been cloned from Populus euphratica Oliv. through a homology based strategy. The isolated 3,210 bp cDNA contains a single 2,862 bp open reading frame (ORF) which encodes a putative H -ATPase protein of 953 amino acid residues, with a significant homology to plasma membrane H -ATPase of Primus persica, Phaseolus vulgaris, Sesbania rostrata and Daucus carota. The predicted protein has a molecular weight of 104,553 Da. The copy number analysis revealed multiple copies of the PM H -ATPase in the P. euphratica genome after digestion of their genomic DNA by the restriction enzymes EcoRI, NdeⅠ, FbaⅠand BglⅡ, and Southern blot.  相似文献   

PRRS ELISA试剂盒检测猪繁殖与呼吸综合征病毒抗体的应用   总被引：2，自引：0，他引：2  

吴延功王志亮  王君玮徐天刚张喜悦  宋翠平许立华 陈溥言 《中国动物检疫》2004,21(6):23-25

利用重组杆状病毒表达的PRRSV核衣壳蛋白作抗原制成ELISA诊断试剂盒，检测人工感染PRRSV猪血清、疫苗免疫抗体和田间血清，并与IDEXX公司生产的试剂盒进行比较。结果表明，该试剂盒在PRRSV感染后8天内就可检出感染性抗体，而用IDEXX公司生产的试剂盒在感染后的18天才检测到感染性抗体，对弱毒疫苗的免疫检测也基本能反映出疫苗的免疫应答状况。对华东地区PRRSV流行病学调查结果表明，PRRSV在国内普遍存在，同时也证明研制的试剂盒，是客观科学调查我国PRRS流行情较理想的检测工具。  相似文献

Experiment for Condensing Heat Transfer Performance in a New Type of Horizontal Three Dimensional Inner Microfin Tubes     

Du Yang Xin Mingdao Huang Shaoming 《保鲜与加工》1995,(5):50-56

A new type of three dimenstional inner microfin tube is devoloped. Under four different pressures and in the range of condensing mass velocities from 33 to 153 kg/m2 . s,and by the experimental study of the three kinds of tubes with different microfin parameters, the performances of the condensation heat transfer for R11 in the horizontal microfin tubes and obtained. The experiments show that the inner microfin tube is a hopeful and nighty effective condensing heat transfer enhancement tube.  相似文献

Research on the Realization of Remote Controlling for Multi-output Power Supply of Communication Equipment Based on Ethernet     

LI Xin  ZHANG Chun  ZHANG Cong-fi  SHI Guang 《保鲜与加工》2006,(9):28-32

According to the requirements of communication power supply, such as high reliability, wide application and high availability, the authors raise a new remote control design for a multi-output power supply for communication equipment based on TCPIP protocol and embedded technology. Then the hardware design is given for the system is discussed based on Ethernet professional chip PRTL8019AS and related circuits. The firmware software design for the salve-computer based TCPIP technology, and the soft design of communieation and control for the master-computer are proposed based on Winsoek and MFC technology in detail A test machine is built to do the testing, the test results prove that the test machine works stably and well, satisfies the design rules and also provides a feasible method for the remote supervise in communication power supplier whose requirement includes remote supervise, no-people on duty and so on.  相似文献
