Cell Lines Or Primary Cells KB luciferase cells
Animal Model
Administration Route
Output Type Luciferase knockdown (48 h; normalized to total protein)
Output Value ~63% knockdown vs untreated
Output Units
Output Notes Knockdown reduced to ANTP-NP level when excess free folate (2 mM) added, indicating folate receptor involvement; negative control siRNA NP not significant.
