  • Primer sequences [1]
  • huNu sorted for Fluidigm C1 runs on 01.23.14 and 01.28.14
  • RNA was extracted from matched whole brain tissue (area corresponding to huNu) or 100,000 sorted NeuN+ nuclei using Zymo MicroRNA Kit

Purpose[edit]

  • To provide pooled RNA-seq libraries of human brain section/sorted nuclei for comparison with Fluidigm C1 single nuclei libraries

Results of Amplification[edit]

  • Run 5ul on gel:

File:01282014 PCR1 Gel1.jpg

Results: 0.1U of RNAseIII (id 81, 85, 89, 93) appears to over fragment this RNA. Anywhere from 0.075 to 0.025 units seems to be effective - sequencing will be needed to determine with condition is best.

Final Library Preparation[edit]

  • Beads purified twice at (0.8x), re-suspended in 10ul
  • PCR on 0.5ul each library using ILMN_PCR_F and either ERCC130R227 or ERCC130R964.
