During the analysis steps of hydrogen deuterium exchange (HDX) mass spectrometry (MS) there is an unavoidable loss of deuterons, or back-exchange. Understanding back-exchange is necessary to correct for loss during analysis, to calculate the absolute amount of exchange, and to ensure that deuterium ...

Quantitative proteomic platforms based on precursor intensity in mass spectrometry (MS1-level) uniquely support in vivo metabolic labeling with superior quantification accuracy but suffers from limited multiplexity (≤3-plex) and frequent missing quantities. Herein, we present a maximally-multiplexed...

Alphaviruses are mosquito-vectored, positive-strand RNA viruses causing rheumatic and neurological diseases. Like all RNA viruses, they encode an RNA-dependent RNA polymerase (RdRp, nsP4). Purification of an nsP4 derivative capable of processive RNA synthesis from a heteropolymeric template has been...

Immunoglobulin light chain amyloidosis (AL) is a life-threatening disease caused by the deposition of monoclonal light chain (LC) and its fragments containing variable (VL) and portions of constant (CL) domains. AL patients feature either monoclonal free LCs circulating as covalent and noncovalent h...

Immunoglobulin light chain (LC) amyloidosis (AL) is a life-threatening human disease wherein free monoclonal LCs deposit in vital organs. To determine what makes some LCs amyloidogenic, we explored patient-based amyloidogenic and non-amyloidogenic recombinant LCs from the λ6 subtype prevalent in AL....

Antibody light chains can aggregate as amyloid fibrils to cause systemic AL amyloidosis. Amyloid deposition requires unfolding of the light chain from its native state, but the mechanistic details of how this occurs are not fully understood. Inhibiting amyloid formation by stabilizing the precursor ...

Immunoglobulin light chain (LC) amyloidosis is a life-threatening disease whose understanding and treatment is complicated by vast numbers of patient-specific mutations. To address molecular origins of the disease, we explored 14 patient-derived and engineered proteins related to κ1-family germline ...

Antigen-antibody interactions play a key role in the immune response post vaccination and the mechanism of action of antibody-based biopharmaceuticals. 4CMenB is a multicomponent vaccine against Neisseria meningitidis serogroup B in which factor H binding protein (fHbp) is one of the key antigens. I...
