Question No amplification using pfu polymerase



Urgent help needed....
I am trying to amplify a gene from strep chormosomal DNA extraction to clone. Works beautifully with TAQ but when i try the same conditions using pfu hot start doesn't work at all.............Have tried manufacturers instructions..doesn't work!! getting desperate...Please trouble shoot...

Have you noticed that pfu polymerase has lower extension rate?

I find it can help to try a range of MgCl2 concentrations in your PCR mix. You'd be suprised what an impact it can have.

It require very high qulity of your template DNA. Did you check your DNA qulity?

I had the same problem with pfu but by using a fresh DNA it worked very well.
try to purify ur DNA sample or fresh extract the dna.

i am really sorry to disturb you but i would like to tell you that right now i am working on an amplification of a gene with pfu and unfortunately it does not work so i was wondering what have you done and if you have resolved the problem. please let me know as soon as possible because these experiments are really important for my university thesis

hello

you should fresh DNA sample.IT works very well when fresh DNA sample is used.
You should also use a blend of Taq nad Pfu.I use 1:2 ratio of taq and pfu.
