Save on Sino Biological Cytokines and MMP Proteins

For researchers working in translational research, cell therapy, immunology, oncology or cancer biology, reliable recombinant proteins are an essential part of the workflow. This autumn, Bio-Connect offers two limited-time Sino Biological promotions to support ongoing and upcoming research projects with selected high-quality protein reagents.

Until December 31, 2026, you can benefit from:

• GMP-grade cytokines: Buy 1, Get 1 Free
• Matrix metalloproteinases: 30% off

These promotions apply to selected products only. The terms and conditions and eligible product names and numbers are listed below.

Buy 1, Get 1 Free on GMP-Grade Cytokines

Sino Biological’s GMP-grade and DMF-filed cytokines are manufactured under stringent GMP-compliant quality management and quality control systems, delivering consistent, high-quality reagents for cell therapy and translational applications. They support cell expansion, activation and differentiation in areas such as cell therapy, immunotherapy, stem cell research, organoid culture and regenerative medicine. Animal-free options are also available.

Buy 1, Get 1 Free: purchase any eligible GMP-grade cytokine and receive a second qualifying product free. It’s a great opportunity to expand your cytokine portfolio while making your research budget go further. Simply add promo code SINO1+1 in the comment section of your webshop or email order to enjoy the offer.

Eligible GMP-Grade Cytokines

30% Off Matrix Metalloproteinase Proteins

Matrix metalloproteinases (MMPs) remodel the extracellular matrix and play key roles in T-cell engager development and conditional activation, supporting protease-mediated mask cleavage, linker screening and activation studies. They are also widely used in cancer biology, immunology, inflammation and disease progression research.

Save 30% on eligible MMP proteins, available across multiple species and formats and including endotoxin-free options ideal for cell-based assays, to support your T-cell engager, conditional biologics, tumor biology and ECM remodeling research. Just add promo code SINOMMP-30 in the comment section of your webshop or email order to unlock your discount.
