How can you use “pei” in a sentence? Here are some example sentences to help you improve your vocabulary:

Keeping the 1: 5 DNA: PEI ratio constant, lower yields were obtained at 0.2: 1 and 0.5: 2.5 DNA: PEI (Figure 4).
For example, a DNA/PEI ratio of 0.4 also produces reasonable numbers of transfected neurons in our system, meaning that the measurement of the DNA and PEI solutions need not be rigorously accurate for the transfection process to work.
This finding underscores the versatility of PEI as a method for introducing genes into postmitotic populations of cells, particularly as our previous efforts to transfect sympathetic neurons using lipid-based reagents (Lipofectamine and Lipofectin) had been unsuccessful.
A maximum of ∼ 9% β-gal +neurons were observed at 3 d post-transfection with 1: 5 DNA: PEI, followed by a progressive decrease from 3 d to 10 d.
PEI may be used in conjunction with adenovirus vectors [ 2, 9, 11, 18, 19] and can be conjugated to various ligands for targeted gene delivery [ 10, 16] or to minimize nonspecific interactions with blood when injected into the circulatory system [ 20].
