General description

500 mL bottle with cap
The Stericup® vacuum filtration system is the most efficient single-use, disposable process for sterile media preparation. It combines a Steritop filter unit with a receiver flask for processing and storing volumes from 150 mL to 1,000 mL in a single, ready-to-use format. Its no-tip, easy-grip flask design and balanced profile improve stability during filtration in tight laminar flow hoods, and the convenient labeling and packaging make it easy to open and track each device. The bottom of the receiver flask is slightly recessed, so you can conveniently stack capped flasks after filtration, maximizing precious refrigeration space. You can also use Steritop bottle-top devices with your own sterile capture flask or bottle.

Features & Benefits

Millipore Express PLUS membrane for fastest flow rates and low protein binding to minimize absorption and protein loss, which affect downstream performance and costs
Durapore membrane for ultra-low protein binding for minimum absorption and protein loss
Snug tight packaging, easy tear-open pouch, and convenient label designs make storing, opening and tracking your devices easy and efficient
Stable base and easy grip design of the Stericup device enable any user to comfortably perform all stages of the workflow in a laminar flow hood
Recessed bottom of Stericup receiver flasks allows flasks to be stacked easily in refrigerated spaces

Nuclear processing of most miRNAs is mediated by Microprocessor, comprised of RNase III enzyme Drosha and its cofactor DGCR8. Here, we uncover a hidden layer of Microprocessor regulation via studies of Dicer-independent mir-451, which is clustered with canonical mir-144. Although...
