==library hybridization== #Aliquot 500ng of preped gDNA libraries and concentrate at <45C down to 3.4ul. If the samples dried up completely, resuspend in 3.4ul ddH2O. #mix the component according to below at RT to prepare hybridization buffer (if precipitate forms, warm the hybridization buffer at 65C for 5 minutes): ##For every reaction, add 25ul of SureSelect Hyb #1, 1ul of SureSelect Hyb #2 (red cap), 10ul of SureSelect Hyb #3 (yellow cap), 13ul of SureSelect Hyb #4, total is 49ul ##For every 4 reactions, add 100ul of SureSelect Hyb #1, 4ul of SureSelect Hyb #2 (red cap), 40ul of SureSelect Hyb #3 (yellow cap), 52ul of SureSelect Hyb #4, total is 196ul #prepare the SureSelect Oligo Capture Library Mix for target enrichment (keep everything on ice for next few steps): ##add 5ul of SureSelect Oligo Capture library and 1ul ddH2O ##prepare 1:1 dilution of the RNase Block (purple cap) ##add 1ul of diluted RNase Block to each capture library and mix thoroughly by pipetting ##keep tubes on ice #prepare library for target enrichment in a separate tube (for the following steps, make sure evaporation is no more than 3-4ul): ##put 3.4ul of prepped library(500ng) into tube B add 2.5ul of SureSelect Block #1, 2.5ul of SureSelect Block #2, and 0.6ul of SureSelect Block #3 ##mix well by pipetting and cap the tubes ##heat up the prepped libraries + blockers at 95C 5min and 65C hold ##maintain the tubes at 65C while load 40ul of hybridization buffer into tube A (# of tubes needed is the # of prepped libraries) ##incubate both tubes at 65C for at least 5 min before go on #put the SureSelect Oligo Capture Library from step 3.4 into tube C and incubate at 2 min (now the thermocycler should have three tubes per sample incubating at 65C) #while maintaining the tubes at 65C, transfer 13ul from tube A (hybridization buffer) into tube C (SureSelect capture library) for each sample #while maintaining the tubes at 65C, transfer the entire content from tube B (prepped libraries) into tube C (SureSelect capture library) for each sample #mix well by pipetting and the hybridization mix should be around 27-29ul #incubate the hybridization mixture at 65C for 24-72 hrs with heated lid at 105C (make sure no extensive evaporation if incubating more than 24hr)
