WebMar 11, 2024 · A: Preparation protocol for Erythro-VLPs: Erythrocyte liposomes were prepared from human RBCs. 14 mg/ml erythrocyte liposomes were incubated in a 3 μ M and 25 mM Triton-X100 solution. The detergent was removed by Amberlite XAD-2 and size-exclusion chromatography (SEC). WebJan 19, 2024 · An approach for discriminating the threo and erythro configurations of polyacetylene glycosides by 1H NMR spectroscopy was developed. Using acetic acid-d4/D2O as the solvent, a relatively larger 3JHH value (7.0 Hz) for the acyclic vicinal diol group was unambiguously assigned to the threo configuration, whereas the smaller value …
