Dear All,
Im planning to use qiagen long range PCR and qiagen seqtarget system to amplify my gene of interest which is 40 kb in size.
The seqtarget provided 4 primers that covers the entire gene of my interest. And i manage to optimize the pcr for these 4 amplicons
But my problem are:
1. the pcr prod showed no bands if i use master mix
2. i get distinctive band if i add each reagents (dntp, q solution, taq, dH2O, primer) one by one (which means that i dont do master mix)
3. But wen i do many samples at a time , i tend to get faint bands.
I desperately need help in solving this issue.
Besides i need to pool these 4 amplicons into one before proceeding with Nextera XT kit for Miseq. So if u pool these faint pcr prod will it affect the pcr quality?
