R&D Systems™ Recombinant Human sCD4 Protein

Description

Extensive quality control produces industry leading bioactivity and lot-to-lot consistency that instills confidence in results and ensures reproducibility. Applications: Bioactivity

Measured by the ability of the immobilized protein to support the adhesion of HeLa human cervical epithelial carcinoma cells. The ED50 for this effect is 1-8 μg/mL. Optimal dilutions should be determined by each laboratory for each application.
