We demonstrated that recombinant baculovirus vectors expressing p35 (Ac-CMV-p35) and eGFP could be transduced into human kidney 293 cells efficiently. The level of transgene expression was viral dose dependent and high-level expression of the target gene could be achieved under the heterogonous promoter.

本研究证明重组杆状病毒载体Ac-CMV-p35和Ac-CMV-GFP能有效地转导人胚肾293细胞,并介导外源基因高效表达,目的基因的表达水平与杆状病毒的感染剂量成正线性相关。

This paper studies the exponential stability of cellular neural networks with time- varying delay by making use of the homoeomorphism theory, the idea of vector Lyapunov function, M- matrix theory and inequality - technique, offering the grounds for uniqueness of equilibrium point existence and the global exponential stability and estimating the exponential convergence rate index.

利用同胚映射理论、向量Lyapunov函数思想、M-矩阵理论和不等式技术,研究了具有变时滞的细胞神经网络模型的全局指数稳定性,给出了判定平衡点的存在唯一性以及全局指数稳定性的一个判据,并且估计了收敛速度指标。

Amplified cells were cultured in PGC culture medium and non-adherence culture flask till idiosome formed, adhered and differentiated.
