2007, (2): 49-55.
Abstract:
Sea surface temperatures (SSTs) in the southwestern South China Sea have been reconstructed for the past 160 ka using the U37k paleothermometer from the core MD01-2392.The temperature differences between glacial times (MISs 6 and 2) and interglacial ...
Study of back-silting strength in the north passage channel of Changjiang Estuary

2007, (2): 56-64.
Abstract:
Temporal and spatial variations of the back-silting strength in the north passage channel of Changjiang Estuary are investigated using the empirical orthogonal function (EOF) method, with the aim to determine the imposed processes and time-scales.Dat...
Establishment of microsatellite-based triplex PCR for parentage analysis of Chinese shrimp Fenneropenaeus chinensis
GAO Huan, KONG Jie, LIU Ping, MENG Xianhong, LUAN Sheng, ZHANG Tianshi
2007, (2): 65-74.
Abstract:
Through exploring the microsatellite primers from the random genome sequences of Chinese shrimp (Fenneropenaeus chinensis), some microsatellite primers were obtained with rich polymorphic genetic information, and a triplex PCR was established using t...
Construction of white spot syndrome virus (WSSV) whole genome phage display library
ZHU Yanbing, YANG Feng
2007, (2): 75-83.
Abstract:
A rebuilt vector pCANTAB 5 EE was obtained by inserting a 34 bp double-stranded oligonucleotide which contained a EcoRV recognition sequence into pCANTAB 5 E.White spot syndrome virus (WSSV) genome DNA was fragmented by sonication to isolate fragment...
Enzymatic properties of UFE, a novel marine fibrinolytic enzyme
WANG Dianliang, LIU Wanshun, HAN Baoqin
2007, (2): 84-93.
Abstract:
A novel potent protease, Urechis unicinctus fibrinolytic enzyme (UFE), was firstly discovered.The enzymatic properties of UFE were further investigated.As a low molecular mass protein, UFE appeared to be very stable to heat and pH.When temperature wa...
