The devices are available with different outlet connectionsSterivex filter units can process volumes up to 1,000 mL or 2,000 mL, depending on the type of membrane used in the device. A choice…

The Steriflip filter unit is designed to work with standard 50 mL centrifuge tubes, which eliminates sample transfer. To filter, just attach the unit to a 50 mL centrifuge tube containing your sample, flip it over, and apply the vacuum. When finished, the filtrate collects in the attached 50 mL centrifuge tube.Steriflip Nylon Net filters are now available in 40, 60 and 100 µm pore sizes, making them ideal for stem cell, cardio…

Sterivac vacuum-driven filter units are ideal for bottle-top filtering directly into receiver flasks at flow rates as fast as 1.5 L/min. The unique "start & stop" filtration action makes setting up, filtering and transferring the unit to another receiver fast and easy. Push a button to stop filtering, move the device to an empty bottle and restart

The Stericap ™ PLUS Universal Bottle-Top Filter Device provides fast, large-volume filtration into any sized bottle.

Dextran Sulfate (MW 500,000) is used as an additive in probe hybridization solutions. Its presence accelerates the rate of hybridization by 10 fold. The addition of Dextran Sulfate favors the formation of probe networks, resulting in greater sensitivity during membrane-bound nucleic acid analysis. The product is supplied as a 50% (w/v) solution.

Hybrisol® Hybridization Solutions are pre-made, ready-to-use solutions optimized for sensitive single and multiple gene copy detection using membrane-based hybridization techniques. They are designed to give maximum signal and clean background for hybridizations performed on nylon and nitrocellulose membranes. Hybrisol® Solution contains 10% Dextran Sulfate, 1% SDS, 50% Formamide, 6X SSC, Sheared DNA, and Modified Denhardt's S…

EMD Millipore's hERG membrane preparations are crude membrane preparations made from HEK293 stable recombinant cell lines, which are ideal HTS tools for screening antagonists against the hERG channel. The membrane preparations exhibit a Kd of 5.2 nM for [3H]-Astemizole. With 10 μg/well hERG Membrane Prep and 3.0 nM [3H]-Astemizole, a greater than 4-fold signal-to-background ratio was obtained.
