- Evaluation of nanoparticle tracking analysis (NTA) in the characterization of . . .
Nanoparticle tracking analysis (NTA) is a relatively new technique for the size characterization of particles between 40 and 1000 nm Recent studies have shown an increasing interest in NTA as a complementary technique in the field of pharmaceutical sciences
- Application Application Note Note - Horiba
Shear Induced Aggregation: mAb otein solutions Figure 6 shows the increase in aggregation when a monoclonal antibody formulation is subjected to shear with the stirrer in the VewS zer sample cell Confounding effects of shear during sample transfer are avoided by applying shear in situ with the stir bar
- NTA: Protein Aggregation - Malvern Panalytical
In this seventh chapter of the Nanoparticle Tracking Analysis (NTA) application and usage review, we discuss the reports of the use of NTA in furthering understanding of aggregate formation in therapeutic proteins The use of the complementary technique of Dynamic Light Scattering (DLS) is also discussed
- Monitoring gold nanoparticle conjugation and analysis of biomolecular binding with . . .
Furthermore, an assay for the detection of mouse IgG was developed using NTA to detect the binding to antibody–AuNP conjugates This assay provided a detection limit of 3 2 ng mL −1; however, the formation of aggregates resulting from the use of a polyclonal antibody and multiple binding sites on the antigen prevented the determination of
- Prediction and Reduction of the Aggregation of Monoclonal Antibodies
Protein aggregation remains a major area of focus in the production of monoclonal antibodies Improving the intrinsic properties of antibodies can improve manufacturability, attrition rates, safety, formulation, titers, immunogenicity, and
- Classification and Characterization of Therapeutic Antibody Aggregates
Protein aggregates may present self-antigens that break B-cell tolerance (stimulating B-cells without T-cell help) to produce neutralizing antibodies (11, 12) Unlike rigid arrays, protein aggregates, however, appear to be irregular and amorphous and thus unlikely to display repeating antigenic motifs (13)
- Comprehensive Guide to Antibody Aggregation and Fragment: Causes, Effects, and . . .
Antibody aggregates poses significant risks to the efficacy and safety of therapeutic antibodies Understanding the mechanisms of aggregate formation, such as structural disruption and disulfide bond formation, is essential for developing strategies to mitigate these aggregates
- A Comprehensive Evaluation of Nanoparticle Tracking Analysis (NanoSight) for . . . - PubMed
Shaking-induced protein aggregation could also be sensitively monitored by NTA In conclusion, NTA analysis can be used as a robust stability-indicating method for the characterization of proteinaceous submicron particles and thereby complement other analytical methods, provided that consistent sample handling and parametric settings are
