Techniques: Expressing, Injection, Construct, Membrane, Marker

( A ) Construct design for the barcoded GFP-CAAX library plasmids. Each plasmid includes an AttB sequence (light blue), HS4 insulator element (medium gray) embedded with a unique 15-nt random sequence barcode (15xN, purple), a 4xnrUAS minimal promoter for tissue-specific Gal4 transcription activation (light gray), GFP-CAAX (green arrow) and SV40 polyA (dark gray). ( B ) Scheme illustrating the experiment-a high-complexity library of barcoded GFP-CAAX plasmids, each containing a different 15xN barcode (dark blue, magenta and yellow rectangles on the plasmids), was injected into 1-cell embryos of heterozygous pIGLET24 zebrafish containing a genomic AttP site on chromosome 24. The library was co-injected together with mRNA encoding for the PhiC31 integrase (red). 5 days later, the larvae were imaged to confirm GFP expression in neurons, and then selected for extraction of genomic DNA from their entire bodies (n=12 larvae). ( C ) the genomic extracts were used as templates for 10-cycle PCR amplification of the barcodes from all genomically integrated plasmids, using primers that specifically target the integration junction (shown in red arrows). The resulting 650-bp amplicon library is then re-amplified with different, internal primers (shown in blue arrows), to attach overhangs for Illumina next generation sequencing (blue) and add a 5-nt sample-specific multiplexing barcode (pink) for pooled sequencing. ( D ) Number of unique high-confidence barcodes identified in each fish, after barcode collapsing and filtering. ( E ) Histogram of barcode abundance for the injected source library and for the barcodes recovered from the fish-integrated plasmids. The injected library displays a narrow distribution, indicating high complexity (many rare barcodes appearing at similar low frequency) while the fish-recovered barcodes display a broader long-tailed distribution (some barcodes appearing much more than others), consistent with intra-fish clonal expansion of the integrated transgenes.

Figure Lengend Snippet: ( A ) Construct design for the barcoded GFP-CAAX library plasmids. Each plasmid includes an AttB sequence (light blue), HS4 insulator element (medium gray) embedded with a unique 15-nt random sequence barcode (15xN, purple), a 4xnrUAS minimal promoter for tissue-specific Gal4 transcription activation (light gray), GFP-CAAX (green arrow) and SV40 polyA (dark gray). ( B ) Scheme illustrating the experiment-a high-complexity library of barcoded GFP-CAAX plasmids, each containing a different 15xN barcode (dark blue, magenta and yellow rectangles on the plasmids), was injected into 1-cell embryos of heterozygous pIGLET24 zebrafish containing a genomic AttP site on chromosome 24. The library was co-injected together with mRNA encoding for the PhiC31 integrase (red). 5 days later, the larvae were imaged to confirm GFP expression in neurons, and then selected for extraction of genomic DNA from their entire bodies (n=12 larvae). ( C ) the genomic extracts were used as templates for 10-cycle PCR amplification of the barcodes from all genomically integrated plasmids, using primers that specifically target the integration junction (shown in red arrows). The resulting 650-bp amplicon library is then re-amplified with different, internal primers (shown in blue arrows), to attach overhangs for Illumina next generation sequencing (blue) and add a 5-nt sample-specific multiplexing barcode (pink) for pooled sequencing.
