Abstract
Transfection arrays are useful to analyze multiple genes at one time. In order to carry out gene transfection, cells are cultured on a plate on which genes are spotted to make extracellular matrix. However, this method is limited by low cell adhesion and transfection efficiency. To overcome these problems, we attempted to construct a novel extracellular matrix protein consisting of a variety of functional peptides. Here we fused the elastin derived peptide Ala-Pro-Gly-Val-Gly-Val (APGVGV) with the cell adhesive peptides, Pro-His-Ser-Arg-Asn (PHSRN) and Arg-Gly-Asp (RGD). The resulting fusion proteins, E12PSGR, had high cell adhesive activity, transfection efficiency, and thermal stability.
