    Separating Inner and Outer Membranes of Escherichia coli by EDTA-free Sucrose Gradient Centrifugation
    通过无 EDTA 蔗糖梯度离心法分离大肠杆菌的内膜和外膜
    作者:  Sheng ShuWei Mi, 日期: 03/20/2023, 浏览量: 434, Q&A: 0

    The envelope of Gram-negative bacteria consists of an outer membrane (OM), a peptidoglycan cell wall, and an inner membrane (IM). The OM and IM have different components of proteins and lipids. Separating the IM and OM is a basic biochemical ...

    Protein Pull-down Assay Using HiBiT-tag-dependent Luciferase Activity Measurement
    使用 HiBiT 标签依赖性荧光素酶活性测量的蛋白质下拉分析
    作者:  Masashi ArakawaEiji Morita, 日期: 03/20/2023, 浏览量: 349, Q&A: 0

    Co-immunoprecipitation or pull-down assays are frequently used to analyze protein–protein interactions. In these experiments, western blotting is commonly used to detect prey proteins. However, sensitivity and quantification problems remain ...

    Molecular Surveillance of Malaria Using the PF AmpliSeq Custom Assay for Plasmodium falciparum Parasites from Dried Blood Spot DNA Isolates from Peru
    使用 PF AmpliSeq定制检测法对秘鲁干血斑 DNA 中的恶性疟原虫寄生虫分子进行疟疾监测

    Malaria molecular surveillance has great potential to support national malaria control programs (NMCPs), informing policy for its control and elimination. Here, we present a new three-day workflow for targeted resequencing of markers in 13
