- this cell lysate was used as it was.
- the Protein Assay was performed using a Bio-Rad Protein assay kit.
- PEG-C9000 greatly improved the expression in a manner dependent on the Anion Z cation ratio.
- Example 4 Gene expression in polyethyleneimine / PEG derivative / plasmid complex A three-component complex of the gene and polyethylenimine PEG derivative was prepared, and this complex was allowed to interact with human hepatoma cell HepG2, and the expression of the luciferase gene was confirmed.
- HepG2 cells were seeded on a 96-well multiplate with 1 ⁇ 10 4 cels / well and incubated for 24 hours.
- Example 2 To (2), a solution of the PEG derivative (Mal-PEG-A / C, Lac-PEG-A / C) produced in Example 1 was added so that the desired anion: cation ratio was obtained. It was left still at 37 ° C for 0 minutes.
- the anion: cation ratio is, specifically, a molar ratio of the charges of polyethyleneimine and the PEG derivative.
- FIGS. 9 and 10 The results are shown in FIGS. Here, the value of _ / + in the figure is the ratio of anion to cation, specifically, the molar ratio of the charge of the PEG derivative to polyethyleneimine.
- protein Means all proteins contained in the cell. "Relative luciferase activity per mg of protein” is a value indicating how much of the protein produced by cells is due to this gene.
- Fig. 9 shows the results for Lac-PEG-A / C, where the expression activity was highest at an anion / cation ratio of 4, which was about three times that of the case without Lac_PEG_A / C. Expression increased.
- Fig. 10 shows the results for Mai-PEG-A / C.
- the expression was increased about 2-fold.
- the obtained syrup was dissolved again in pure water, ion-exchanged with Amberlite B-120, and freeze-dried to obtain a PEG derivative having a dalcoside side chain and a carboxyl side chain. Yield The ratio of sugar side chains to carboxyl side chains in the polymer as calculated by 45 mg go NMR spectrum was 19:81.
- FIGS. 11, 12, and 13 show NMR spectra of GuI-N-PEG-C, Gal-N-PEG-C, and Man-N-PEG-C, respectively. All publications, patents and patent applications cited herein are hereby incorporated by reference in their entirety. Industrial applicability
- gene expression activity is higher than that of a conventional gene-chitosan complex, and cell-specific gene delivery can be achieved.
- gene expression activity is higher than that of a conventional gene-polyethyleneimine complex, and cell-specific gene delivery can be achieved.
