    (RSS) (BioRxiv All) Structure of HIV-1 Env glycoprotein on virions reveals an alternative fusion subunit organization and native membrane coupling: An effective vaccine for Human Immunodeficiency Virus type-1 (HIV-1) has yet to be developed, and detailed characterization of functional Env glycoprotein, the primary antigenic target on virions, has remained elusive. While engineered Env trimers recapitulate many aspects of functional Env, key… https://www.biorxiv.org/content/10.64898/2026.01.09.698652v1?rss=1&utm_source=dlvr.it&utm_medium=mastodon #BioRxiv #MassSpecRSS

    (RSS) (ChemRxiv) High performance interface for boosting ion transmission in native mass spectrometry and beyond.: Electrospray ionization (ESI)-based native mass spectrometry (MS) has been extensively used to study non-covalent protein complexes and their structural aspects in the gas phase. As such it has a stable place in the portfolio of modern structural biology and biopharmaceutical analysis techniques. It is also promising as an… https://dx.doi.org/10.26434/chemrxiv-2026-011h9?rft_dat=source%3Ddrss&utm_source=dlvr.it&utm_medium=mastodon (RSS) #chemrxiv #MassSpecRSS
