Affinity Peptides With pH Sensitivity for the Enrichment of CD38+ Cells
Biotechnology and Bioengineering, EarlyView.ABSTRACT The selective enrichment of cell populations based on surface markers is critical for the advancement of gene and cell therapies. Current antibody‐based cell isolation methods, such as fluorescence‐ and magnetic‐activated cell sorting (FACS and MACS), offer high specificity but are limited by scalability, cost, and potential adverse effects on

Tetrazine Ligation in Living Systems: Beyond Fast Kinetics to Effective Bioorthogonality
Chemistry – A European Journal, EarlyView.Rapid reaction kinetics (k2) alone do not ensure successful tetrazine ligation in living systems. This review introduces ‘effective orthogonality’—focusing on chemical survival, availability, and encounter—as a practical framework. We highlight how bottlenecks shift from cellular sinks to in vivo delivery limits, offering design strategies for reliable
