Transfection of mammalian cells, human lymphocytes (above) and human carcinoma HeLa cells (below), by means of calcium alginate microbeads bearing immobilized DNAs. Phase-contrast micrographs (left panel), and fluorescent micrographs (right panel) show expression of the pEGFP-C1 plasmid containing the CMV promoter and the EGFP gene.
