الانتقاء المناعي السلبي: طريقة لتنقية الخلايا البائية من خلايا الدم المحيطية أحادية النواة

Executive Industry Relevance

Negative immunomagnetic selection enables the rapid and reproducible purification of B cells from heterogeneous PBMC samples, supporting high-confidence target validation and mechanistic studies in hematological disease research. This approach minimizes contamination from non-B cell populations, increasing predictive confidence in downstream assays and translational workflows. The method is strategically positioned for early discovery and preclinical research in immunology and oncology portfolios.
