在这里,我们报告的蛋白质(牛血清白蛋白,BSA)颗粒,这是暂时不溶的使用一种新的,还原不稳定的二硫化物为基础的交联剂的制造。交联后,蛋白质颗粒在水溶液中保持其完整性,并在还原环境下优先溶解。我们的数据表明,交联剂的裂解在反应性氨基上没有留下化学残基。通过瞬时不溶性PRINT蛋白颗粒实现自我复制RNA的递送。这些蛋白质颗粒可以为药物和基因递送提供新的机会。
Herein we report the fabrication of protein (bovine serum albumin, BSA) particles which were rendered transiently insoluble using a novel, reductively labile disulfide-based cross-linker. After being cross-linked, the protein particles retain their integrity in aqueous solution and dissolve preferentially under a reducing environment. Our data demonstrates that cleavage of the cross-linker leaves no chemical residue on the reactive amino group. Delivery of a self-replicating RNA was achieved via the transiently insoluble PRINT protein particles. These protein particles can provide new opportunities for drug and gene delivery.
