Test condition for haplotyping[edit]
- Continue with lab note 11.3.11
- Tagmentation and PCR
Samples[edit]
- Non-MDA ~1pg cell lysates: from same patch of cells as MDA samples, Ptnase treatment, Nextera
- MDA samples: 1ul each of all 8 MDA product [17ct-2, 22ct-3, 27ct-3,4, 30ct-1,2,3,4] ranging from 1ng - 20ng
Procedure[edit]
- Tagmentation: 1ul 1:50d Trp-I, 1ul LMW buffer, fill up to 5ul
- PCR: 15ul Kapa QPCR MM, 0.3ul each B/O primer, fill up to 30ul
Results[edit]

Simplify protocol[edit]
- Skip purification after MDA
- Combine 2 rounds of PCR
Samples[edit]
- 10ng jurkat + 1ul dALS + 1ul dNS + 7ul MDA MM --> take 3ul for tagmentation
- 1ul each of all 8 MDA product [17ct-2, 22ct-3, 27ct-3,4, 30ct-1,2,3,4] ranging from 1ng - 20ng
Procedure[edit]
- 3ng jurkat in 10ul MDA MM --> 65C, 3min
- 5ul tagmentation reaction
- 30ul PCR: 15ul Kapa QPCR, 0.6ul Adaptor 1, 0.6ul barcoded-adaptor 2 (GA-A2 Indx73-80)
- 58C, 4 cycles; 62C, 8 cycles
Results[edit]
- Consistent with previous curve, suggesting 1 step PCR works
- Jurkat gDNA directly with MDA MM seems fine with tagmentation and PCR, suggesting purification can skip
