Branched polymer increases transfection efficiency of plasmid. (A) 7.5 nmol of HK or 0.375 nmol of HHK4b was mixed with PCI-luc, and luciferase activity was measured in MDA-MB-435 cells as described in Materials and Methods. *, P < 0.05, HHK4b versus HK, Student’s t-test. (B) In addition to MDA-MB-435 cells, HHK4b as a sole carrier was significantly better in augmenting gene expression compared to HK in CHO, MDA-MB-231, CRL-5800 and MCF7 cells. *, P < 0.05, HHK4b versus HK in CHO, MDA-MB-231, CRL-5800 and MCF7, Student’s t-test.
