| abstract |
The invention relates to methods for introducing target biopolymers (e.g., nucleic acid molecules, proteins, etc.) and other compounds (e.g., non-polymeric organic molecules, such as steroids) into cells (e.g., eukaryotic cells). The invention further relates to compositions comprising target biopolymers and other compounds. In certain aspects, the invention relates to the deposition of target biopolymer-containing mixtures onto surfaces optionally followed by contacting these target biopolymer-containing mixtures with cells (e.g., eukaryotic cells). Additionally, when the target biopolymers are nucleic acid molecules, expression of these nucleic acid molecules by cells which are contacted with the target biopolymers may be monitored or detected. |
