High Purity

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

Superior Bioactivity

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.
