Dive Deeper into Research with Recombinant Proteins

MCE provides a wide range of high-quality recombinant proteins, including cytokines, enzymes, growth factors, hormones, receptors, transcription factors, and antibody fragments. These proteins are crucial for various cellular mechanisms such as cell growth, signaling, and differentiation, and many of our recombinant products are essential tools for research in protein structure and function, disease mechanisms, and drug targets.

Over 12,000 Recombinant Protein Products

• High Purity Grade: >95%
• Outstanding bioactivity
• Excellent Lot-to-Lot consistency

• Low endotoxin levels: < 1 EU/μg
• Flexible package size options available

High Purity

The purity of MCE’s mouse IL-13Rα₂ exceeds 95%, as determined by SDS-PAGE under reducing conditions and HPLC analysis.

Superior Biological Activity

MCE’s human GM-CSF promotes the proliferation of TF-1 cells, with an ED₅₀ of less than 0.5 ng/mL.

Excellent Lot-to-Lot Consistency

The ED₅₀ values of MCE’s human VEGF165 from three distinct lots are highly consistent.

Activity Comparison

A side-by-side comparison of the ED₅₀ values shows that MCE’s human VEGF165 is more potent than that of a competitor brand.

TNF-α (HY-P7058) treatment upregulates the expression of adhesion molecules on the surface of HUVECs. Additionally, by increasing the expression of CXCR4 and VLA-4, it enhances the inflammatory chemotaxis of MMCLs, greatly improving their transendothelial migration efficiency.
