First 12 WGBS of K-Bay Bleaching Samples

Using the Zymo Pico Methyl Seq Library Prep Kit For 12 Montipora DNA Samples from KBay Project

Goal Start prepping 12 of the 40 samples for this project
Results All libraries worked, the concentrations are very high
Takeaways Looks like ~70ng/ul is overloading the TapeStation and I should either dilute the whole library or dilute before adding. I might elute the library from the cleanup in a larger volume next time. Using the KAPA mix causes greater yields.

This library prep followed the closely the protocol for the Zymo Pico Methyl Seq Kit from me. See that protocol for detailed descriptions of each steps. Tables and values specific for this prep are included below.

Bisulfite Conversion

  • Followed exact steps as in protocol
  • Put samples in fridge overnight

Post-BS Conversion cleanup 20210510

  • Followed exact steps as in the protocol

Amplification with Prep-Amp Primers

  • Followed exact steps as in the protocol
  • Priming Master Mix calculations (PMM):
    • 2ul PrepAmp Buffer * 12.3 = 24.6ul
    • 1ul PrepAmp Primer * 12.3 = 12.3ul
  • PrepAmp Master Mix calculations (PAMM):
    • 1ul PrepAmp Buffer * 12.3 = 12.3ul
    • 3.75ul PrepAmp PreMix * 12.3 = 46.12ul
    • 0.3ul PrepAmp Polymerase * 12.3 = 3.69ul
  • Dilution calculation of PrepAmp Polymerase to add 0.5ul:
    • 0.3 PrepAmp Polymerase * 12.3 = 3.69ul
    • 0.2ul DNA elution buffer * 12.3 = 2.46ul

DNA Clean and Concentrator

  • Followed exact steps as in the protocol

First Amplification

  • Followed exact steps as in the protocol
  • 1st Amp Master Mix calculation:
    • 12.5ul Library Amp Mix * 12.3 = 153.75ul
    • 1ul Library Amp Primers * 12.3 = 12.3ul

Second DNA Clean and Concentrator

  • Followed exact steps as in the protocol

Second Amplification with Index Primers

  • Followed exact steps as in the protocol, except I used the KAPA HiFi HotStart Ready Mix instead of the Library Amp Mix and I used only 13ul of it, and that the indexes had been combined so I only used 1ul of the combined indexes
  • Table for components in tubes for amplifications:

21 12ul 13ul 1 1ul
22 12ul 13ul 2 1ul
26 12ul 13ul 3 1ul

1X Bead Clean

  • Followed exact steps as in protocol
  • Samples were Qubited immediately so they were put on an ice bucket not frozen yet
