16:0 Biotinyl Cap PE

Vesicle fusion and vesicle microreactorsTo prepare functionalised AuNP vesicles, we first electroformed POPC vesicles in 0.5 M sucrose solution with 2 wt.% 16:0 Biotinyl Cap PE. When fluorescent lipids were present, these were at 1 wt.%. In the calcein dilution and protein expression experiments, vesicles were formed via emulsion phase transfer (see above), with 0.5 M sucrose/glucose density gradient. Next, 150 nm streptavidin-coated AuNPs (Nanopartz, CO, USA; product C11-150-TS-50; 2.5 mg ml−1) were added to the vesicles 1:9, with the sample vortexed for 30 min to drive conjugation. VIMs were formed as before, but with 0.25 M NaCl in the external solution. Vesicles were fused by focusing and applying a laser of 150 mW (at trap) or greater on the VIM interface. Vesicles were manipulated in space using a <100 mW laser (at trap) to avoid unintentional fusion (Supplementary Note 13). We also used Aurora-DSG Nanoparticles (AuNP-labelled lipids; 1–2 nm; Avanti), which did not result in fusion when embedded in the membrane at 2 wt.%.石家庄pg电子娱乐游戏app 生物制品供给有关產品:DSPE-PEG-LysozymeStearic acid-PEG-COOHDSPE-PEG-PLGADSPE-PEG-rhuMAb HER2-Fab’or scFv(二硬脂酰基磷脂酰工业乙醇胺-聚乙二醇-*靶点蛋白酶)cRGD-PEG-N3DSPE-PEG-Trastuzumab(二硬脂酰基磷脂酰无水乙醇胺-聚乙二醇-*靶向疗法淀粉酶)DSPE-PEG13-TFPDSPE-PEG-LSLERFLRCWSDAPA(二硬脂酰基磷脂酰工业乙醇胺-聚乙二醇-*靶向治疗蛋白质)DSPE-PEG-CSSRTMHHC(二硬脂酰基磷脂酰乙酸乙酯胺-聚乙二醇-*靶向疗法核蛋白)R6H4-PEG-DSPE上文章的内容的内容的来源各样学术期刊或学术论文,见谅知识产权侵权请结合各位删掉!
