Sound direction modifies the inhibitory as well as the excitatory frequency tuning characteristics of single neurons in the frog torus semicircularis (inferior colliculus)

We describe the site-specific enzymatic biotinylation of recombinant anti-estradiol Fab fragments through a 13 amino acid acceptor peptide translationally fused to the C-terminus of the Fd chain. The Fab-peptide fusion proteins were secreted to the periplasm of Escherichia coli, purified, and biotinylated in vitro using biotin ligase, biotin, and ATP. The E. coli biotin ligase (the BirA protein) was produced as a novel N-terminal fusion protein with glutathione S-transferase (GST) and purified in one step from bacterial cell lysate using a Glutathione Sepharose affinity column. The purified fusion protein worked as such (without cleavage of the GST part) for the in vitro biotinylation of the Fab fragments. After the removal of nonbiotinylated Fab fragments by monomeric avidin chromatography, the overall yield of biotinylated Fab was 40%. The site-specifically biotinylated Fab fragments (BioFab) were tested in streptavidin-coated microtitration wells, to which they were shown to bind linearly with respect to the amount of BioFab added, specifically as indicated by biotin inhibition, and tightly with a half-life of several days. Moreover, the enzymatic BioFab exhibited uniform antigen binding affinity unlike the same recombinant Fab fragments biotinylated through random chemical conjugation to surface lysines. Finally, the BioFab demonstrated its potential as a well-behaving immunoassay reagent in a model competitive assay for estradiol.

单色光石英退偏器的退偏机理及性能研究

研究了单色光石英退偏器的退偏机理；定义了退偏度作为衡量退偏器性能的物理量。从实验上在４４０～９２０ｎｍ的光谱范围测试了器件的退偏度，结果表明：只要器件的结构角适当，或者适当调节入射光束的截面大小，便可对某一单色线偏振光实现很好的退偏。     

面向对象数据库（OODB）与关系数据库（RDB）之比较研究

面向对象数据库至今还没有权威的定义，为把握与了解面向对象数据库的实质，我们采用比较研究法，首先从数据库发展史来剖析面向对象数据库与关系数据库之间的联系与差异。然后在功能，性能上分别讨论各自的亿势与劣势，阐面向对象数据库的本质与特征。     

浅谈中华老字号六味斋豆腐干系列包装再设计

随着社会经济的发展,面对消费者货比三家的消费之道,为了跟上或者引领消费者的消费理念,商家在不断地自我更新和自我完善。产品包装的更新换代成了商家必须考虑的问题之一。承前继后,不断发展是设计师与商家一直努力追求着的理念。本文以六味斋豆腐干系列包装再设计为例浅析再设计的方法和原则。在一连串的整合、分析、探讨后,我们在企业品牌核心理念的基础上,用包装在设计的手段来更新我们的生活。
