Antibody aggregation

Introduction. Formulating monoclonal antibodies (mAbs) at high concentrations may allow delivery via subcutaneous injection, but at high concentrations these formulations may exhibit reduced stability and increased viscosity. 1 Irreversible aggregation of proteins can provoke an immune response. 2 Subcutaneous injection typically requires viscosities below ….

The nearest neighbors and support vector regression models have the best performance in terms of the errors for the validation. Overall, our machine learning models performed considerably better than other existing tools for predicting antibody aggregation rate (Fig. 2).

With years of exploration in antibody engineering, Creative Biolabs has built a full-scale in silico technology platform. Antibody aggregation could be triggered by partial unfolding of its domains, leading to monomer-monomer association followed by nucleation and growth.

Gaining understanding on the aggregation behavior of proteins under concentrated conditions is of both fundamental and industrial relevance. Here, we study the aggregation kinetics of a model monoclonal antibody (mAb) under thermal stress over a wide range of protein concentrations in various buffer solutions. We follow experimentally the monomer …Background. Protein aggregation during monoclonal antibody (mAb) production can occur in upstream and downstream processing (DSP). Current methods to determine aggregate formation during cell culture include size exclusion chromatography (SEC) with a previous affinity chromatography step in order to remove disturbing cell culture components.The phenomenon of protein aggregation is a common issue that compromises the quality, safety, and efficacy of antibodies and can happen at different steps of the manufacturing process, including ...On account of the identification of aggregation-prone regions and their contribution to the thermodynamic stability of the protein, predicting and decreasing the aggregation propensity of monoclonal antibodies become available. With years of exploration in antibody engineering, Creative Biolabs has built a full-scale in silico technology platform.

Aggregation of human therapeutic antibodies represents a significant hurdle to product development. In a test across multiple antibodies, it was observed that IgG1 antibodies aggregated less, on average, than IgG2 antibodies under physiological pH and mildly elevated temperature. This phenomenon was …It led a $50 million funding round for vernacular news app NewsDog. Chinese internet giant Tencent has just made its first bet on India’s news ecosystem. Newsdog, an India-focused vernacular news aggregator, raised $50 million (Rs341 crore)...Controlling monoclonal antibody aggregation at the upstream stage itself can significantly reduce the burden on downstream processing and can improve the process yield. Hence, we have investigated the use of sugar osmolytes (glucose, mannose, sucrose and maltose) and formulation excipients (mannitol, polysorbate 20 and polysorbate 80) … ….

The aggregation analyses described above are typically carried out on mAb samples during the formulation development phase, although, as previously described, efforts are underway throughout the biopharmaceutical industry to determine propensity to aggregate as early in the antibody discovery process as possible, where samples will be greater ...The aggregation of therapeutic antibodies during the manufacturing process is problematic because of the potential risks posed by the aggregates, such as an unexpected immune response. One of the hallmark effects of trehalose, a disaccharide consisting of two alpha-glucose units, is as a chemical chaperone with anti-aggregation …

Jul 29, 2016 · Antibody aggregate level is normally controlled in bioprocessing by polishing steps after Protein A capture. This paper studied the Higher Order Structures (HOS) of antibo … Antibody aggregate is a common issue in therapeutic antibodies, which may compromise product efficacy and cause adverse effects. Perfusion reduces bispecific antibody aggregation via mitigating mitochondrial dysfunction-induced glutathione oxidation and ER stress in CHO cells. Pritam Sinharoy 1, Aaron H. Aziz 1,Hydrophobicity has been used to predict antibody aggregation in earlier works. Citation 13, Citation 16 In addition, in our previous work, we also found SCM_pos is an important feature for the antibody aggregation rate. It should be noted that SCM includes a distance cutoff of 10 Å, so SCM_pos_H2 does not mean only the positive charges on the ...
