Intended Use:
Designed for NK cell and CAR-NK cell preparation from peripheral blood (PBMC) and cord blood.Process development stage: Accelerates early-stage cell therapy development while reducing time and cost, facilitating faster advancement of CAR-NK/NK cell therapy products.
Performance Specifications
Performance Parameter Specification NK Cell Purity (%) >90% CD3+ Cell Residual (%) <1% NK Cell Expansion Fold >5,000-fold Cell Viability (%) >80% Data Summary:
As NK cells are increasingly developed as allogeneic, off-the-shelf therapeutics, stringent requirements are placed on both expansion capacity and purity. The Blue Kit® NK Cell Expansion System enables:
• Robust and reproducible expansion - achieves >10,000-fold NK cell proliferation within 14 days
• Donor-to-donor consistency - maintains stable expansion rates across different donors
• High purity NK populations (left panel)Notably, 14-day expanded NK cells retain potent tumoricidal activity even after cryopreservation and thawing (right panel).
T Cell Purity (Pre- vs Post-Selection)
T Cell Expansion Performance:
The high-purity T cells (＞98% CD3+) are then activated using GMP-grade T Cell Activation Reagent and expanded in serum-free T Cell Basal Medium,
demonstrating:＞100-fold proliferation (Day 10-14),Consistent viability ＞90%
Maintained T-cell functionality (CD4+/CD8+ ratio preservation)
Cell Expansion & Viability
CD19 CAR Transduction Efficiency:
The CAR Gene Transduction Module, when combined with Viral Transduction Enhancer B (Viral E-hancer B),
demonstrates:＞60% CAR+ T cells by flow cytometry 2-3 fold enhancement in lentiviral transduction efficiency vs. standard protocols
