1381 and 1392 using Invitrogen maxi prep kit have too much RNA. After treating sample 1381 and 1392 with 0.5 ul RNAse (Qiagen) at 37oC , After 2-3 hours, there are still too much RNA on the gel, adding 10 ul (100mg/ml RNAse) into the sample and incubate at 37C for another 4-6 hours, precipitate DNA with isoprapanol. There isn't pure (Ratio is low), so the DNA reading is very low (minus value).There is too much RNase protein. Paul run the sample on the qiagen column again and there is no too much DNA left. Need re-do maxipre for this two sample.
