H*****e 发帖数: 120 | 1 Hi experts,
I need to sequence PI3K and PTEN in tumors for determine whether there is
mutation. But I do not know much about sequencing mutations since I only
work kinase for years. So I have a few basic questions, wish to get answers
here:
1.RNA or DNA, The tumor sample will be provided by a colleague in Hospital.
I can get both DNA and RNA purified. Should I sequence DNA or RNA after I
PCR them out?
2.If only 1 copy has mutation and the other copy is wt, can routine sequence
in core lab detect it? Or I have to use the so-called pyrosequence?
Thanks! | k*******s 发帖数: 214 | 2 The fast way is to PCR the target region and sequence. If only one mutation
, there will be two peaks at the specific sit and it can seen from the
sequencing chromatograph.

the future.
2. Yes.
