Yoğunluk Gradyanlı Santrifüjleme: CLL Hücrelerini Periferik Kandan İzole Etmek İçin Bir Yöntem

Executive Industry Relevance

Isolating primary CLL cells from peripheral blood enables mechanistic studies of B-cell signaling and drug response in a disease-relevant system. This method supports target validation and phenotypic screening by providing purified primary cells for downstream assays. It enhances predictive confidence in preclinical models by reducing variability from mixed cell populations.
