title: A nanophosphor-based method for selective DNA recovery in Synthosomes.
abstract: A nanocompartment system composed of an ABA triblock copolymer, where A is poly(dimethylsiloxane) and B is poly(2-methyloxazoline), has been developed for selective recovery and detection of DNA. Translocation of TAMRA-labeled complementary primers into the nanocompartment system has been achieved through two deletion mutants (FhuA Delta1-129; FhuA Delta1-160) of the channel protein FhuA. Translocation was monitored by fluorescence resonance energy transfer through hybridization of the TAMRA-labeled primer to the complementary sequence of a nanophosphor-DNA-conjugate, which reduces its half-life (FhuA Delta1-129, 16.0% reduced; FhuA Delta1-160, 39.0% reduced).
