High purity AAV vectors make difference to CNS experiments
14 April 2015: Differences in AAV purity can affect the success of in-vivo CNS applications. A recent publication by Acta Neuropathologica Communications (1)compares AAV standards from two alternative sources in US & Europe. As it turns out, improved purity standards increase the survival of neurons significantly that can be measured 12 weeks post-operation. Cell survival in turn affected the results of the experiment massively,underlining the necessity to choose the best possible tools available for your lab work. more....

Improved lentiviral applications with non-toxic transduction enhancementWorking with lentivirus vectors is on the rise. Low transduction efficiencyremains a key issue, specifically when working with primary cells, as was confirmed in a survey at Washington's AACR meeting.
In vitro, the cationic polymere polybrene is conventionally used to increase lentiviral transduction rates. Polybrene functions by breaking down charge repulsion between virion and cell surface, increasing the accessibility for the virus particle. Despite its advantages, the use of polybrene is limited due to cytotoxic side effects at higher concentrations (Figure 1) excluding its use inin vivo applications or when hard to transfect cell types necessitate high virus titers. More...
Fine-tuning of gene expression levels is reaching new heights; latest data indicate full control is now possible, even in primary cellsThe secret code to full control of gene expression levels is “TET”, Tetracycline-controlled transcriptional activation. In combination with tailor-made adenoviral vector elements you will control and guide expression intensity for better, clearer research results. There are close to no limits concerning cell type; TET works even with primary cells. This applies to knockdown and overexpression systems equally well. TET in combination with the right adenoviral delivery system allows for stunning results not possible only a few months ago. More.....

90% knockdown rates on GPCR's now easy to achieveMembrane-spanning GPCRs are notorious for their high resistance against shRNA knockdown applications. Even newest approaches only manage mediocre knockdown rates. Strategies achieving less than 60% knockdown on mRNA levels  are still accepted into high impact publications today (Impact factor - 6.5). A scan through recent literature confirms this being the norm rather than the exception [2-3]. More....
