Our aim is the biolistic transfection of organotypic cultures of rat visual cortex with plasmids coding for neurotrophic factors, which then become expressed for limited periods of time during postnatal ontogenesis. Out of two commercially available devices, we adopted the handheld 'Helios Gene Gun' instead of the stationary PDS-1000He (both Biorad, Munich, Germany). This device allows multiple...
Targeted DNA double-strand breaks have been shown to significantly increase the frequency and precision of genome editing. In the past two decades, several double-strand break technologies have been developed. CRISPR-Cas9 has quickly become the technology of choice for genome editing due to its simplicity, efficiency and versatility. Currently, genome editing in plants primarily relies on deliv...
Transfer of foreign genes into plant cells can be accomplished by several methods: agrobacterium-mediated, microinjection, biolistic particle bombardment and electroporation. The last one is frequently used for transfection of plant protoplasts for transient gene expression. Electroporation is a simple procedure and allows transfecting a large number of cells at one time. Square wave-modulated ...
Ion channels and PSD-95 are colocalized in specific neuronal subcellular locations by an unknown mechanism. To investigate mechanisms of localization, we used biolistic techniques to express GFP-tagged PSD-95 (PSD-95:GFP) and the K(+)-selective channel Kv1.4 in slices of rat cortex. In pyramidal cells, PSD-95:GFP required a single PDZ domain and a region including the SH3 domain for localizatio...
Red algae are extremely attractive for biotechnology because they synthesize accessory photosynthetic pigments (phycobilins and carotenoids), unsaturated fatty acids, and unique cell wall sulfated polysaccharides. We report a high-efficiency chloroplast transformation system for the unicellular red microalga Porphyridium sp. This is the first genetic transformation system for Rhodophytes and is...
