Product description and procedure summary:Target cells are either selected or depleted by incubating the sample with the biotin antibody cocktail followed by incubation with magnetic Streptavidin Nanobeads (Cat. No. 480015\/480016). The magnetically labeled fraction is retained by the use of a magnetic separator. The untouched cells are collected. If these are the cells of interest; do not discard the liquid. Some of the downstream applications include functional assays, gene expression, phenotypic characterization, etc.Sample Preparation:Enzymatic digestion of mouse brain followed by myelin removal is recommended to achieve the highest purity and yield. There are several protocols published that can be applied. As a general guideline, Trypsin digestion followed by a 70\/37\/30% percoll gradient will increase final purity and yield.Scale up volumes if using 14 ml tubes and Magnet, and place the tube in the magnet for 10 minutes.
