Most moisture analyzers use chemicals or high temperatures. Not AquaLab. Instead, an infrared beam focused on a tiny mirror determines the precise water activity of the sample. That water activity reading is then translated into moisture content, based on a product-specific calibration model.What Products Work?Most products with less than 40% moisture (by weight) will work using the dew point method. Products with moistures a…

A pooled BAC library is an invaluable tool for PCR-screening. It allows for the easy retrieval of BAC clones of interest. This type of library is especially useful when genome size is large and creating an arrayed library is cost-prohibitive. We typically construct a minimum 5X BAC library and BAC clones are then pooled and distributed in 96-well plates. Each well will contain about 400-500 original BAC clones. HMW DNA isolati…
