Example Expression Performance

93% Purity After One Step Protein A Purification

HPLC analysis illustrates the high yield and-purity possible with B-Body® Bispecific antibody expression and one-step purification. Bispecific Ab was transiently expressed in CHO cells and purified by Protein A purification. HPLC analysis provides readouts of yield and purity as well as valuable, predictive insights for analytical development, downstream processing, and formulation optimization.

High Performance Across a Range of Formats and Samples

This dataset comprises 549 protein samples (~493 unique sequences) expressed in CHO at 50–200 mL scale, spanning IgG1, One Arm, 1×1, 2×1, 2×2, and trispecific formats.

Panel A shows crude yield after capture purification (x-axis) versus crude purity (y-axis), illustrating that the service can successfully express antibodies across a broad range of molecular formats and a large range of antibody specificities.

Panel B summarizes purity distributions for crude and polished samples. In each box plot, the central line represents the median, the box edges mark the 25th and 75th percentiles, and whiskers indicate the statistical minimum and maximum values (outliers excluded). In all cases, polishing improved purity, with the lowest observed values exceeding 85%, demonstrating that the service reliably delivers high-quality material across diverse antibody architectures.
