tn5-059 NXTA_ME_B vs ez-tn5 NXTA_ME_B for secondary fragmentation troubleshooting R3[edit]


  • will test with 1000 cell, 6 ng DNA john chang samples to make sure they work. when preparing 100 cell, 500 cell GM12878 libraries used custom transposons with ez-tn5 for secondary fragmentation and adaptor addition. tn5059 should be better.

AFTER IVT RNA HAS ALREADY BEEN GENERATED AND CLEANED WITH ZYMO

8. single strand synthesis MMLV RT (Clontech)

20 uL reaction

1. Add 2.5 uL 20 uM (100 ng total) RANDOM HEXAMERS to RNA sample. Bring to final volume of 11.5 uL with
   Nuclease free H2O

2. heat the mixture to 70C fo 3 minutes.  Immediately cool on ice.

3. Add the following to the reaction.
   4  uL 5X first strand buffer
   2  uL dNTP mix
   2  uL 100 mM DTT
  .5 uL SMART MMLV RT and mix (ADD LAST!!!!!)
  ____
   20 uL total

4. Incuvate first at Room Temperature for 10 minutes. Then incubate at 42C for 60 minutes.

5. Terminate the reaction by heating at 70C for 10 minutes



9. RNase H digestion

  • Use .5 Units for 20 uL reaction. Stock is at 5 Units/ul, thus dilute 10X and use 1 uL per reaction.

a. Add 1 uL of 10X diluted Rnase H to the reaction.

b. Incubate for 20 minutes at 37C.



10. Second strand synthesis: Adding sss_NPA_prmr primer and polymerases. Can incubate at higher temps (usually at 16C since RNA is nicked) since sss_NPA_prmr has a high Tm.

a. Add 2.5 uL of 20 uM sss_NPA_prmr to each reaction. 

b. Incubate solutions for 2 minutes at 65C. Cool immediately on ice.


d. Add polymerases etc to reactions

          taq5X: Add  5.875 uL, Incubate at 72C for 8 minutes


11. Clean DNA with AMPURE beads depending. elute in 20 uL and concentreate. (can also use qiaquick)

  • USED AMPURE DNA BEADS AT 1:1.8X RATIO
  • add 45 uL N-H2O
  • add 135 uL beads per reaction
  • elute on 20 uL

can quantitate with Qubit or on TBU gel.


11.5. Eluted DNA into 20 uL per sample, since when eluting in smaller amounts more sample is lost. Thus after elution used vaccum centrifuge commentator to concentrate sample size to ~4-5 uL per sample.

  • Also ~4-5 uL per sample is preferred for transposition, which has always been performed in low volume solutions. Additionally less transposome will be needed when doing that.

RAN FOR 16 MINUTES


12. Fragmenting and 3' End tagging with Custom Nextera transposome

USING NXTA_ME_B WITH TN5059, SAMPLES 2,4,6,8

EZ-TN5 NXTA_ME_B FOR CONTROL, SAMPLES 1,3,5,7

1 uL custom buffer D6
2 uL lysed/pure genomic DNA (X ng/pg DNA)
X uL Nuclease free H2O
1 uL prepared T7 transposomes (MAKE SURE TO ADD LAST)
___________
5 uL total solution

Incubate at 55C for 6 minutes, cool briefly on ice after


13. Protease digestion of transposase, protease inactivation

To each tube, add:
1 uL  Qiagen Protease, for 5 uL reaction 1 uL of .5 for .1 AU final. (stock is 5 AU and diluted 10X. want .5 AU/uL final [])
Incubate: 50C 10 minutes, 70C 20 minutes



14. Fill in reaction

  • Add 6 uL 2X taq polymerase, run at 72C for 3 minutes. (same as nextera)


15. PCR addition of barcodes MAKE SURE TO USE NEXTERA INDEXES!!!!!

KAPA SYBR FAST qPCR mix until saturation, X35 cycles

  • terminate before curves saturate (usually cycle 6-8)


16. Gel Size selection

  • gel size select from 400-800 bp, follow gel size selection protocol
  • do not need to include controls.
