Hi, After a quick look on Google: 'The GFP+ gene contains GC-rich codons as well as mutations that improve the fluorescence signal (T65), making it suitable for ‘fluorescein’-oriented fluorescence optics.'
Therefore the construct you make will be in the exact same was as if you were generating an expression vector with GFP rather than GFP plus.
As ever just make sure the tag is on the correct terminus and in frame with the rest of you gene of interest and you should be all set! And also check the codon bias, depending on what cells you are trying to express your gene in this could also have an effect.
