The structure was visualized with PyMOL
The structure was visualized with PyMOL. Collectively, the experimental results and modeling suggest that the RBD has a well-defined structure of a three-helix fold, which forms a spatial cluster of important amino acids in the interface of helix 1 and 3. 3.4. process of B19V and further explain the efficient neutralization of B19V by antibodies against the VP1u region. 2. Materials and Methods 2.1. Cells and Viruses UT7/Epo cells were kindly provided by Eiji Morita (Tohoku University or college School of Medicine, Sendai, Japan) and produced in RPMI 1640, 5% fetal calf serum (FCS), 2 U/mL recombinant human being erythropoietin (rhEPO), supplemented with l-glutamine and penicillin/streptomycin. Human being plasma from a parvovirus B19 infected person (5 109 virions/L, genotype 1) was from our donation center (CSL Behring AG, Charlotte, NC,…
