Depositor Comments

The pMM310-BlamVpr plasmid reagent was obtained through the NIH AIDS Reagent Program, Division of AIDS, NIAID, NIH: pMM310(Cat#11444) from Dr. Michael Miller. The DNA sequences encoding for Beta-lactamase (Blam) was replaced with HindIII-mCherry-PC-NotI-PC-YFP-BamHI encoding sequences.
