WiMedia超宽带平台的ECMA-368标准MAC协议

因IEEE 802.15.3 MAC集中式架构应用于超宽带系统存在问题,WiMedia联盟提出了新的ECMA-368MAC协议.本文着重研究了WiMedia MAC针对超宽带高速无线个域网的低功率、Ad-hoc网络及P2P移动性等特点设计的分布式架构及相关协议,并在文章的最后提出WiMedia MAC今后改进的建议.     

Effect of arginine on stability of GST-ZNF191（243-368）

For better understanding the chemical or biological information of ZNF191(243-368), we expressed the fusion protein of GST and ZNF191(243-368), and used it to obtain the binding DNA sequence of this zinc finger protein. But in the process of expression and purification, we found this fusion protein slowly degradated. For resolving this problem, we simultaneously added charged amino acids L-Arg and L-Glu to the solution of fusion protein, and demonstrated that this method can dramatically increase the stability of this fusion protein. This method can make the fusion protein suitable for the continuous works, especially for situations where high protein concentration and long-term stability without precipitate and degradation of protein are required.
