Покрытые карбоксиметил-декстраном суперпарамагнитные наночастицы оксида железа (superparamagnetic iron oxide nanoparticles (SPIONs), были синтезированы с использованием метода ко-преципитации в водной среде. Затем они были конъюгированы с антителами против GD 2, мечеными флуоресцентным красителем (флуоресцеин-5-малеимид). Далее конъюгат anti-GD 2-mAbs@SPIONs был очищен с помощью диализа.</p><p>Концентрацию железа, покрытия (карбоксиметил-декстран) и белка (антитела против GD 2) в полученной наносуспензии измеряли с помощью тиоцианатного метода, с помощью количественной оценки реакции полимера с антроновым реактивом и по методу Бредфорда, соответственно. С применением динамического светорассеяния были получены данные о поверхностном заряде конъюгатау, установлен их гидродинамический размер и характер дисперсности. Анализ МР-контрастирующих свойств проводили с использованием метода МРТ фантомного образца на ЯМР-спектрометре.</p><p>Взаимодействие конъюгата anti-GD 2-mAbs@SPIONs с клетками линии U 251 (глиобластома человека) регистрировали с помощью конфокальной микроскопии.</p></sec><sec><title>РЕЗУЛЬТАТЫ</title><p>РЕЗУЛЬТАТЫ.

Было показано специфичное накопление препарата в клетках глиобластомы по сравнению с наночастицами, неконъюгированными с антителами против GD 2.</p></sec><sec><title>ЗАКЛЮЧЕНИЕ</title><p>ЗАКЛЮЧЕНИЕ.

They were then conjugated with antibodies against GD 2 labeled with a ﬂuorescent dye (ﬂuorescein-5-maleimide). Next, the anti-GD 2-mAbs@SPIONs conjugate was puriﬁed by dialysis.</p><p>The concentration of iron, coating (carboxymethyl-dextran) and protein (antibodies against GD 2) in the resulting nanosuspension was measured using the thiocyanate method, by quantifying the reaction of the polymer with an antron reagent and by the Bradford method, respectively. Using dynamic light scattering, data on the surface charge of conjugates were obtained, their hydrodynamic size and the nature of dispersion were established. The analysis of MR-contrasting properties was carried out using the MRI method of a phantom sample on an NMR spectrometer.</p><p>The interaction of the anti-GD 2-mAbs@SPIONs conjugate with cells of the U 251 line (human glioblastoma) was recorded using confocal microscopy.</p></sec><sec><title>RESULTS</title><p>RESULTS.
