==set up the suppressor oligo mixture== the average concentration of cpg97k probe is ~20ng/ul (~600nM).The volume of probe in a 10ul capture reaction is 2.5ul. The volume of suppressor oligo is 1ul/capture reaction. The mole ratio of suppressor oligo: probe is 100:1. So the suppressor oligo concentration in a 10ul capture reaction should be: ((600nM*2.5)/97k)*100=1.5nM. I prepared the 100x suppressor oligo as 150nM/each, then dilute to 10x working mixture. I adjusted the concentration of oligoes according to their read abundance. For cpg55B subset, the read abundance range from 430-1673. The oligo(50uM) volume used is 0.5ul/each. The final volume of mixture = (50uM*0.5ul)/150nM = 167ul. So I take 0.5ul oligo (50uM)/each and added 162ul ddH2O to get the final volume of 167ul. For cpg55A subset, I adjusted the ration according to the abundance range. A1-E1: take 5ul/oligo; (25ul) F1-H1: take 3ul/oligo; (9ul) A2-H3: take 1ul/oligo; (14ul) A4-H12: take 0.5ul/oligo; (63ul) add ddH2O to get the final volume of 167ul. ==recapture the PGP samples with two cpg97k subsets== The probe set was prepared by Alan. {| border="1" cellpadding="5" cellspacing="0" align="center" |- | align="center" style="background:#f0f0f0;"|'''No ''' | align="center" style="background:#f0f0f0;"|'''sample ''' |align="center" style="background:#f0f0f0;"|'''sample concentration''' | align="center" style="background:#f0f0f0;"|'''10xLigase buffer''' | align="center" style="background:#f0f0f0;"|'''template+cpg97k_A(25.6ng/ul_06/18) vol+suppress oligo+H2O''' | align="center" style="background:#f0f0f0;"|'''template+cpg97k_B(21ng/ul_06/18) vol+suppressor oligo+H2O''' |- |09_1||NA21687*1 062507 ||95.4ng/ul ||1ul||2+2.5ul+1ul+3.5ul||2+2.5ul+1ul+3.5ul |- |09_2||NA21781*1 102307||120.2ng/ul ||1ul||2+2.5ul+1ul+3.5ul||2+2.5ul+1ul+3.5ul |- |09_3||NA21833*1 101807||121.5ng/ul||1ul||2+2.5ul+1ul+3.5ul||2+2.5ul+1ul+3.5ul |- |09_4 ||NA21660*1 053007||120.3ng/ul||1ul||2+2.5ul+1ul+3.5ul||2+2.5ul+1ul+3.5ul |- |09_5 ||NA21731*1 101807 ||127.3ng/ul||1ul||2+2.5ul+1ul+3.5ul||2+2.5ul+1ul+3.5ul |- |09_6 ||NA21846*1 100407||151.3ng/ul||1ul||2+2.5ul+1ul+3.5ul||2+2.5ul+1ul+3.5ul |- |09_7||NA21070*1 100406 ||311.2ng/ul||1ul||2+2.5ul+1ul+3.5ul||2+2.5ul+1ul+3.5ul |- | ||positive control||Jurkat bis-gDNA 200ng/ul||1ul||1+1ul+1ul+6ul||1+1ul+1ul+6ul |- | ||negative control||0||1ul||0+1ul+1ul+6ul||0+1ul+1ul+6ul |} dNTP concentration 10mM(NEB) ddH2O Ligase Buffer Ligase Amplitaq dNTP 2U/ul AmpliTaq Stoffel fragment; 0.5U/ul AmpLigase; 1mM dNTP: 0.5ul 0.1ul 0.1ul 0.2ul (10mM)0.1ul x80 40ul 8ul 8ul 16ul 8ul ==PCR== Template 10ul x9 2X iProof Mastermix 50ul 450ul AmpF6.3SoL (10uM) 4ul 36ul AmpR6.3SoL (10uM) 4ul 36ul 50X SYBG I 0.4ul 3.6ul H2O 31.6ul 286.2ul [[Image: 20090622_cpg97k_A subset_No09_1~7.jpg| 20090622_cpg97k_A subset_No09_1~7.jpg]]20090622_cpg97k_A subset_No09_1~7 [[Image: 20090622_cpg97k_B subset_No09_1~7.jpg]]20090622_cpg97k_B subset_No09_1~7 Egel purify the A subset captured targets. qiaquick purify the B subset captured targets.
