B-Xpander™ – Unleash the Power of B Cell Expansion

This cutting-edge multimeric human CD40L cytokine is designed to overcome the inefficiencies of current B cell expansion methods, offering a powerful solution for researchers and clinicians alike.

Why B-Xpander™?

B-Xpander™ stands out by mimicking the natural interaction between CD40L and CD40 molecules on B cells, eliminating the need for additional enhancers. This results in a more efficient and robust B cell activation and proliferation process. Here’s what makes B-Xpander™ a game changer:

• Enhanced Activation and Proliferation: B-Xpander™ significantly boosts the proliferation of human primary CD19+ B cells, ensuring you get the cell number of cells you need without the hassle.
• High Bioactivity and Purity: Produced using a proprietary protocol in a GMP-compliant CHO cell line, B-Xpander™ guarantees high bioactivity, verified through rigorous ELISA and cell-based assays.
• Consistency and Safety: With low endotoxin levels and animal-component-free production, B-Xpander™ ensures batch-to-batch consistency and safety for your research and clinical applications.

Transforming Adoptive Cell Therapy (ACT)

B-Xpander™ is an essential tool in the field of adoptive cell therapy. It supports the expansion and activation of B cells alongside T cells in tumor-infiltrating lymphocytes (TILs), leading to improved tumor-specific TILs. This enhancement translates into greater efficacy in targeting and eliminating cancer cells, making B-Xpander™ an essential tool in immunotherapy research.

Proven Efficacy

Experimental data showcases B-Xpander™’s superior performance:

• B Cell Proliferation: B-Xpander™ increases the proliferation of human primary CD19+ B cells more efficiently than other types of multimeric human CD40L.
• B Cell Activation: It activates B cells without the need for additional enhancers, as evidenced by the increased expression of CD86/CD19 positive cells.
