Vehicle for delivery of particles to a sample

摘要

The present invention relates to a vehicle for delivery of particles to a sample of cells. The vehicle includes a barrier to retain the particles, which barrier in one embodiment is a frangible, dissolvable or meltable material. Once released into the sample, the particles are useful in methods to lyse or disrupt cells or in methods to separate cellular components from one another if the cells in the sample are already lysed or disrupted.
