Single-Domain Antibodies for Brain Targeting
Inappropriate activation of the Fc receptor-expressing cells by antibodies can lead to cytokine release and toxicity. On the other hand, their long circulation half-life results in poor contrast in im…

ADC Development Robust Despite Lackluster Performance
The agent is internalized by the tumor cell after it is bound to the cell by the mAb end of the ADC molecule. Inside the tumor cell, the ADC breaks down into its components, which releases the cytotox…

Preclinical Evaluation of Product Related Impurities and Variants
This may be attributed to the complexities related to the use of cell lines, media formulation, and other bioprocessing steps that are prone to variability to varying degrees (4).
The inherent …

Quality by design for biotechnology products—part 1
In some cases, an IgG1 isotype is ideal for cell killing, whereas IgG2 is a favored isotype for eliminating the effector function of an antibody on target binding. For further enhancement of cell kill…

Safety Drives Innovation in Animal-Component-Free Cell-Culture Media Technology
By Tom Fletcher, Holden Harris
Regulatory expectations for cell-culture-based biologics production processes changed dramatically once it was discovered in 1996 that a fatal disease (variant Creut…

Applications of Surface Plasmon Resonance for Detection of Bispecific Antibody Activity
Blincyto targets cell surface proteins CD19 and CD3 simultaneously, helping to put T cells within reach of the targeted cancer cell with the goal of allowing the T cells to inject toxins into cancer c…
