  • ✓ Illumina ChIp-seq prep: Pc-TF ChIP samples 1-6 (Day one)


Illumina ChIP-seq prep
> Follow manufacturer's protocol, with some modifications
> Samples (dated 12/20/10):

  1. "32, 126-1 myc" (hPc-TF)
  2. "33, 126-1 IgG" (hPc-TF mock)
  3. "36, 132-8 myc" (TF)
  4. "37, 132-8 myc" (TF mock)
  5. "38, FTRx K27m" (plain cells)
  6. "39, FTRx K27m" (plain cells mock)
