Published: March 2021

In monoclonal antibody (mAb) production, aggregates represent a major class of product-related impurities that needs to be removed by the downstream process. Protein A chromatography is generally less effective at removing antibody aggregates under typical conditions, and in most cases aggregate removal relies on a subsequent polishing chromatography. Here we describe a procedure for effective removal of antibody aggregates using the mixed-mode chromatography resin Capto MMC ImpRes. Clearance of aggregates was confirmed by analytical size-exclusion chromatography (SEC) and native gel electrophoresis.

Autophagy has emerged as an essential quality control pathway in plants that selectively and rapidly removes damaged or unwanted cellular components to maintain cellular homeostasis. It can recycle a broad range of cargoes, including entire organelles, protein aggregates, and even invading microbes. It involves the de novo biogenesis of a new cellular compartment, making it intimately linked to endomembrane trafficking pathways.

Objective: Self-criticism (SC) is a central transdiagnostic factor in several psychopathological conditions, influencing the development and maintenance of symptomatology. The importance of this construct has stimulated quantitative and qualitative research about it. The main purpose of this systematic review is to highlight which qualitative methods have been used most frequently and which are most suitable for studying SC.

Unlabelled: Despite some skepticism regarding the amyloid hypothesis, there is growing evidence that clearing amyloid by targeting specific species of amyloid (plaque, oligomers, fibrils, and protofibrils) for removal has therapeutic benefits. Specifically, there is growing evidence that, in mild cognitive impairment and mild dementia due to Alzheimer's disease (AD), robust and aggressive removal of amyloid can slow cognitive decline as measured by global instruments, composite measures, and cognitive testing. Furthermore, clinical efficacy signals coupled with clear biomarker changes provide the first evidence of disease modification.
