A method for evaluating the stability of a separator, including the steps of: preparing a separator; determining the elongation properties of the separator by using dynamic mechanical analysis (DMA); comparing the determined value with the stability standards of the elongation properties; and classifying a separator as a stability-passing separator when the determined values satisfy the stability standards, and classifying a separator as a stability-failing separator when the determined values do not satisfy the stability standards, after the comparison.

Disclosed is a gene therapy vector in which the occurrence of recombination is minimized. In order to minimize the occurrence of recombination, which is a major problem in the production and infection of a retroviral vector virus that continuously expresses a therapeutic gene during virus replication, a cleaved MCMV promoter was prepared by cutting the MCMV promoter on the basis of a repeat sequence, and the cleaved MCMV promoter was introduced to prepare a vector. It was confirmed that the vector having the cleaved MCMV promoter incorporated therein does not cause recombinations even after being incubated multiple times, and shows a continuous expression of the therapeutic protein, and in cells transfected with the virus containing the vector, cell death effectively occurs when a prodrug is administered thereto. Accordingly, the vector with minimized recombination occurrence of the present invention can be advantageously used for the treatment of cancer.

Disclosed is a separator which includes a porous polymer substrate including a polymer showing a variation in phase angle represented by the following Formula 1 at 0.1 Hz depending on an increase in temperature. An electrochemical device including the separator is also disclosed.Variation in phase angle at 0.1 Hz=[(Phase angle&#x2212;Phase angle)/(Phase angle)]&#xd7;100&#x2265;0%,&#x2003;&#x2003;[Formula 1]wherein Phase anglemeans the phase angle of the porous polymer substrate at 0.1 Hz and 190&#xb0; C., and Phase anglemeans the phase angle of the porous polymer substrate at 0.1 Hz and 280&#xb0; C.
