The therapeutic antibody landscape has expanded rapidly, with monoclonal antibodies (mAbs) established as a dominant class of biologics across oncology, autoimmune, and infectious diseases. At the same time, the number of investigational antibody candidates continues to increase, placing pressure on development pipelines to deliver candidates efficiently.

​AACR Immuno-Oncology Conference (AACR IO) 2026 was held in Los Angeles from February 18-21. The conference featured talks on basic, translational, and clinical research in immunology, inflammation, and immunotherapies for cancer, with 600+ scientists in attendance.

Bispecific antibodies (bsAbs) are engineered molecules capable of simultaneously binding two distinct antigens or epitopes. This property enables mechanisms of action not achievable with conventional monoclonal antibodies, including immune cell redirection, dual pathway inhibition, and targeted payload delivery. As a result, bsAbs have become a major focus in therapeutic antibody development, particularly in oncology.

Learn what makes an antibody developable, including stability, aggregation, manufacturability, formulation, and in silico prediction methods.

January 2026 deal activity leaned heavily toward bispecific, trispecific, and ADC assets, particularly in oncology and immunology, alongside steady investment in AI-enabled target discovery and antibody engineering platforms. Several of the month’s largest transactions focused on late preclinical and early clinical programs, pointing to continued pharma interest in differentiated antibody modalities with well-defined mechanisms as the year gets underway.

This article examines HEK293 and CHO across biological characteristics, productivity, glycosylation, product integrity, and application-specific strategy, integrating findings from recent comparative studies.

PepTalk 2026 highlights and event recap. Biotech antibody conference!

Bispecific antibodies (bsAbs) represent a rapidly advancing class of therapeutic biologics engineered to simultaneously bind two distinct antigens or epitopes. Their dual-targeting capability enables novel mechanisms of action, including redirected cytotoxicity, receptor clustering, and enhanced specificity, which are being exploited across oncology, immunology, and infectious disease applications.

Discover how machine learning and protein language models transform antibody developability, improving antibody design, screening, and biologics development.

Antibody affinity is a core metric in immunology and biopharmaceutical science. It refers to the strength of the interaction between a single antigen epitope and the paratope (binding site) of an antibody. In the case of VHH antibodies, also called single-domain antibodies or nanobodies, this interaction occurs through the unique, compact paratope located on their heavy-chain-only variable domain.
