The Smallest Changes Lead to the Most Significant Discoveries

Transcription

1 The Smallest Changes Lead to the Most Significant Discoveries The StellARray Gene Expression System When using predefined normalizers, one often ignores small changes in gene expression. The dogma is that those small changes represent noise and are not relevant. In actuality, small changes in expression of key genes can have significant impact on metabolic pathways, and may consequently alter cell behavior. Even housekeeping genes change expression profiles,dependingonthemediaorenvironmentalfactorsto which they are exposed. The simplest way to recognize relevant gene expression changes is the StellARray Gene Expression System. Follow these three steps from database search to publishable results: n GeneSieve Query search a gene or biological pathway to screen 15 million publications and find the best StellARray Product n StellARray qpcr Arrays primers arranged in 96-well and 384-well formats for real time PCR n Global Pattern Recognition (GPR) Analysis Tool analyze data in minutes without housekeeping genes Visit togeta20%discountonyourfirstorderofstellarray GeneExpressionSystemProducts.

18 Stain DNA, not nature. How can you protect yourself, the environment, and your DNA sample? Answer: SYBR Safe. Fact is, it s just as effective as ethidium bromide, yet it s not a hazardous agent. So it s not only better for the environment, but better for you. And since SYBR Safe uses blue light for visualization, your DNA sample won t be damaged by UV, so you ll get better cloning efficiencies. Next time you re staining DNA, be sure to make the safer choice for yourself and the environment. Get SYBR Safe Invitrogen Corporation. All rights reserved.
