The performance of these 3 classes of polylysine analogs was evaluated by assessing eGFP and IgG production in transient gene expression experiments with CHO DG44 cells , which revealed that protein production generally increased with increasing molecular weight and that at comparable molecular weight , the hyperbranched analogs were superior as compared to the dendritic and linear polylysines .
