The cells targeted by the Nanobeads are either selected or depleted by incubating your sample with the directly conjugated magnetic particles. The magnetically labeled fraction is retained by the use of a magnetic separator. After collection of the targeted cells, downstream applications include functional assays, gene expression, phenotypic characterization, etc.Note: For Human CD4 Nanobeads, please refer to the protocol found on the product webpage for MojoSort\u2122 Human CD4 Nanobeads (Cat. No. 480013\/480014).
