Spheroplast and protoplast
WebE. coli spheroplasts can be used to deliver DNA vectors into plant protoplasts. The use of fluorescent dyes showed that 25–100% of the protoplast population was associated with 1–9 spheroplasts following incubation with several fusogens. Electron microscopy demonstrated spheroplasts attached to protoplasts via a plasma membrane protrusion … WebProtoplast and spheroplast preparations allow the transfer of macromolecules into cells and provide the basis for the generation of engineered organisms.
