Vector-Based RNAi Support
Explore the “Getting Started” and “Troubleshooting” sections for solutions to top inquiries and common problems. Browse through the “Guides and Tools” section to access comprehensive product-related support resources.
Getting Started
- What are the benefits of using a vector to deliver RNAi?
- Do you offer an inducible system for shRNA expression? If so, how does it work?
- What is a dose response curve or kill curve? And can you outline the steps involved?
- What is the difference between miR RNAi and shRNA?
- What is the difference between adenovirus and lentivirus systems?
Troubleshooting
- I’m trying to create my entry clone but am seeing mutated inserts. What should I do?
- I’m seeing a low level of gene knockdown or no gene knockdown. What can you suggest I try?
- I’m seeing some basal expression of my shRNA of interest in the absence of tetracycline induction when using the BLOCK-iT™ H1 construct or pLenti4/BLOCK-iT™-DEST construct. What could be causing this?
- I’m getting different sized colonies after TOP10 E. coli transformation when using the miRNA lentiviral expression system. Which one should I use?
- I’m getting a low viral titer with my miR RNAi lentiviral construct. What should I do?
