As described, this is my first time to use these plasmids for overexpressing the gene of my interests.
BTW:
the pCDF1-MCS2-EF1-copGFP is based on FIV not HIV, so I am not sure whether psPAX2 and pMD2.G could be used.
Thanks!
For the envelope, of course, you can do pseudotyping with pMD2.G.
How could I get the P-value from the mean, SEM, and n of different groups in the t-test without the original data? For detail, I would like to know the P-value between BMP-2: 50ng/ml group and the...
