Info

New aliquots of the 4 pools were mailed to the University of Colorado on 10/13/2021 for deeper sequencing. Data was retrieved on 11/09/2021

The four pools were mailed to the University of Colorado’s Genomics Core on 03/23/2021. Pools were ran on 03/30/21. Data uploaded 4/02/2021.

Use iProof Polymerase for this. We can play around with KAPA afterwards to see if we don’t need 2 taqs in house

Used this r-script to bind the Masterkey to the pool and mid plate map, this plate map, and the 2017 plate map to make this demux key

Reagents and Ordering

EcoR1 (20,000 units/ml)
MseI (10,000 units/ml)
T4 DNA ligase buffer (400,000 units/ml)
DNA polymerase (BioRad iProof or KAPA HiFi)
BSA (1 mg/ml)-We have this in 20 mg/ul
1 M NaCl-We have this at 5M
DMSO
EcoR1 adaptors (We need 1 uM MIDed in plates)
Mse1 Adaptors (10 uM stock probably need to dilute from 100 uM)
IIllpcr2 (10 uM working)
Illpcr1 (10 uM working)
Pool of above 2 primers (5 uM working of each)
