4、lasmablast differentiationwhile increasing antibody class switching to IgG1. IPI-3063 is a p110 selective compound with an IC50=0.1nM in p110-specific cell-based assays and cellular IC50 values for the other class I PI3K isoforms are atleast 1,000-fold higher (IC50=19011318 nM for p110, IC50=102.835
5、.7 nM for p110, IC50=418.8117.2nM for p110). IPI-3063 is very potent in reducing p-AKT (significant effect at 1nM). IPI-3063 also reduces p-ERK1/2 with a significant effect at 10nM. IPI-3063 is very potent, achieving a significant decrease in B cellsurvival when present at 10nM 1.PROTOCOLKinase Assa

9、ood mononuclear cells (PBMCs) are first purified from blood by density gradient centrifugation.Human B cells are then purified from PBMCs by negative selection. B-cell purity is increased from 4% to70% as measured by FACS analysis using anti-CD19 PE conjugated antibody. Purified B cells are seededat
