Figure 5

(A) Gel electrophoresis of pDNA coated with either 10 or 40 dips (5 seconds drying time) recovered over a period of 7 days. (B) HaCaT cell transfection efficiency as determined by flow cytometry using recovered pDNA (pEGFP) surface-coated onto microneedles for 1, 5, or 7 days. Data presented as mean ± SD (n=4); One way analysis of variance, P > 0.05.
