  • We show here that transient RNAi of endogenous or exogenous gene, which has been achieved after short-term transfection with the gene-targeting 21mer dsRNA (siRNA), 27mer dsRNA or shRNA-generating DNA vector, does not fail for 2-3 days after onset of apoptosis.

  • A number of methods are in use or under investigation for introducing DNA into cells (a process known as transfection) - using viruses, chemical agents or physical injection. - latest science and technology news stories

  • ELISA, western blot, and molecular biology methods such as transfection and microRNA techniques, high throughput screens, or computer sciences to integrate and analyze genetic, molecular, physicochemical, functional and behavioral data would be viewed as added value.

  • After failing for along time, trouble shooting and all, I realised that there was no DNA in the tube she'd given me... strange that the transfection didn't work huh?

    It could be worse...

  • “These nanocarriers developed by our team have a variety of applications in medication and as a gene transfection agent for biological research,” said Dr Yi-Yan Yang, who led the project team comprising Yong Wang, Shujun Gao, Wen-Hui Ye and Ho Sup Yoon.
