The CD133/PROM1 protein is critical for multiple processes including glomerular epithelial cell differentiation and retinal morphogenesis, showing biased expression in tissues such as lung and kidney. CD133/PROM1 Protein, Rat (HEK293, Fc) is the recombinant rat-derived CD133/PROM1 protein, expressed by HEK293 , with N-mFc labeled tag.
