In Topic: Problem/qPCR, 2 peaks en melting curve

26 July 2012 - 09:07 PM

It may be due to residual  genomic DNA in your RNA miniprep.

Try to digest your RNA with "RNase-free DNase" and then perform qPCR. Hopefully, you would not have that unwanted peak :)

In Topic: Pen/Strep from Sigma unit confusion

It's 100X concentrate;

Streptomycin 10'000 μg/ml

Penicillin 10'000 Units/ml

By adding 1ml of this antibiotics solution to 100ml (99+1) medium you would have 100μg and 100 Units of Streptomycin and  Penicillin, respectively.

you can also perform colony PCR using vector-insert primers to confirm correct orientation.

You would have to do a control transformation in order to rule out this possibility.
