Method for preparation of microprojectiles for efficient delivery of biologicals using a particle gun

摘要

The present invention relates to a process for uniform and efficient delivery of metal projectiles into living cells and tissue of plants and animals, by bombarding the cells with biological coated on metal bead particles. The metal bead particles are heated in dry oven to high temperature, prior to coating with DNA and by substituting ethanol with isopropanol while coating the particles with DNA, to give several fold higher expression of the nucleic acid delivered into cells.
