Transfection of Wild-Type Amoeba via Electroporation with Bacterial Feeding Support

Executive Industry Relevance

Efficient genetic manipulation of wild-type Dictyostelium discoideum using electroporation with bacterial feeding support addresses a key bottleneck in functional genomics for non-axenic strains. This approach enables robust target validation and mechanistic studies in physiologically relevant amoeba systems, supporting early discovery and de-risking in cell biology-driven pipelines. The method expands the toolkit for genetic engineering in model organisms where axenic adaptation is not feasible, enhancing translational continuity and predictive confidence.

Strategic Applications in Biopharma R&D

Early Discovery & Target Validation

• Enables direct interrogation of gene function in wild-type amoeba, supporting pathway clarification.
