LCM samples collected 10-09-2013 (10022013 handcut 2 1.4ng/ul)


Purpose

  • Generate totoRNAseq libraries using RNaseIII digestion on LCM collected samples of human brain pyramidal neurons - same as 10032013 using 10 cells per sample
  • Determine minimum number of nuclei that can be used for the library preparation

Results of Amplification

  • Run 5ul on gel:


Final Library Preparation

  • Beads purify (0.8x), re-suspend in 50ul
  • Beads purify again at 0.8x (if primer dimer band was apparent)
  • Resuspend beads in 10ul
  • Run 1ul on gel:
