Tic spectrometer (Applied Photophysics, UK). The samples were excited with the same laser that was used for phosphorescence measurements [30,31]. The fluorescence time profiles were recorded at 460 nm using an R928 photomultiplier (Hamamatsu). SODF was calculated as the difference between TPP fluorescence in an air (oxygen) atmosphere and in a vacuum.Treatment of the baculoviruses on the surface of nanofiber textiles doped with TPPBaculoviruses in TMN H insect medium (Sigma) (25 or 50 ml; approx. 56104 PFU) were applied to nanofiber textiles and treated as described above. The liquid containing the virus was then collected from the surface of the nanofiber textiles; 26100 ml of insect medium was added to extract the remaining virus; and the combined virus fractions were transferred to a 24-well dish containing Sf9 cells grown on coverslips.Confocal fluorescence and fluorescence lifetime imaging microscopyThese measurements were carried out using a MicroTime 200 inverted epifluorescence confocal microscope (PicoQuant, Germany) [31]. The configuration used in these analyses included a pulsed diode laser (LDH-P-C-405, 405 nm, PicoQuant) providing 80 ps pulses with a repetition rate of 40 MHz, a 505DRLP dichroic mirror, an LP500 Pentagastrin custom synthesis long-pass filter (Omega Optical), a water immersion objective (1.2 NA, 606) (Olympus) and a PDM SPAD detector (MPD, USA).Treatment of the mouse polyomavirus and the recombinant baculovirus in TPPS get 79983-71-4 solutionsViruses were incubated in 100 ml of appropriate media; (see above) containing different concentrations of water-soluble TPPS (0, 0.001, 0.005, 0.010 ) for 30 minutes either in darkness or upon irradiation. The media containing the viruses were then used for infection of the cells growing on coverslips.Continuous irradiation of the nanofiber materials in the presence of AMAA piece of the nanofiber material was peeled off of the supporting polypropylene textile, coiled around a quartz plate (1064061 mm), and inserted into a thermostatted 10 mm quartz cell (22uC) containing a 1024 M aqueous solution of AMA. The cell was irradiated using a 300 W stabilized Xe lamp with an optical cut-on filter (l 400 nm). The changes in UV/VIS absorbance due to the formation of oxidized products were recorded at regular time intervals and compared with the changes observed in a blank solution without irradiation.Viral infection of cellsAdsorption of the polyomavirus to the surface of the 3T6 cells was performed by incubating the virus and cells together for 1 hr at 0uC. Then, 1 ml of pre-warmed DMEM containing 10 FCS was added to each well, following which the cells were incubated at 37uC in a 10 CO2 air humidified incubator for 20 hours and finally fixed. Adsorption of the baculovirus to the surface of the Sf9 cells was performed by incubating the virus and cells together for 1 hr at room temperature. The medium was then removed, and 1 ml of 1326631 pre-warmed TMN H insect medium containing 10 FCS was added to each well, following which the cells were incubated at 27uC for 36 hours and subsequently fixed.Viruses and cellsSpodoptera frugiperda cells (Sf9) were cultured as a monolayer at 27uC in TNF-FH medium containing 10 fetal calf serum (FCS), as described by Hink [42]. The recombinant baculovirus pVLVP1, carrying the mouse polyomavirus VP1 gene driven by a polyhedrine promoter, was used to infect insect cells [43].
