− | RNAseq protocol:
| + | [[Notes]] |
− | Flash freeze tissue from six snakes, two organs per snake
| |
− | RNA range: 100 ng to 10 micrograms
| |
− | --> how do we know that the correct portion of tissue was sampled?
| |
− | Convert RNA to mRNA using polyT oligonucleotides attached to beads, such that mRNA base pairs with beads
| |
− | Convert mRNA to cDNA with RT (reverse transcriptase, uses RNA as a template to make DNA) and dNTP)
| |
− | | |
− | -RNA fragmentation, cDNA synthesis, and clean-up
| |
− | high throughput sequencing has only ~75bp of accurate reads
| |
− | fragmentation takes one long mRNA and cuts it into similarly sized fragments so that there are more edges to read from
| |
− | How to prime every RNA simultaneously? Generate every possible hexamer for the primers (4^6 different combinations)
| |
− | Product:
| |
− | Look at images in pptx
| |
− | Second band of images: gel purified RNA
| |
− | Third band of images: reamplified (considered good cDNA library for RNAseq)
