Biogene's Viral RNA Mag 96 Kit have been optimized for use with biological fluids and cell-free samples such as serum, plasma, swabs, and cell culture media. RNA isolation from cell-free samples presents some unique challenges compared to RNA isolation from tissues or cultured cells. These include low viral titers, large volumes to be processed, and sample complexity. Also, the procedure must be compatible with real-time qRT-PCR. The Mag Viral RNA Kits address all of these issues, without the need for organic solvents or RNA precipitation, eliminating the problems often encountered with filter-based RNA isolation methods such as clogging, large elution volumes, and inconsistent yields.
