Paper Serum Stability and Physicochemical Characterization of a Novel Amphipathic Peptide C6M1 for SiRNA D
Peptide C6M1
Delivery Success Class no
In Vivo Flag no
Uptake Confirmed no
Label Confidence high
In Vitro Functional Effect yes
Endosomal Escape Evidence
Peptide Concentration Peptide stock 1 mM; complexes formed at molar ratio (C6M1:siRNA) 30:1 for knockdown; incubated 20 min RT before use.
Rna Concentration 50 nM siRNA final concentration (western blot knockdown); also tested 5–100 nM (optimum 40–50 nM).
Mixing Ratio Molar ratio (C6M1:siRNA) = 30:1 for transfection (gel shift shows full encapsulation at ≥15:1; higher ratios improve stability).
Formulation Format Noncovalent peptide/siRNA complex (electrostatic co-assembly)
Formulation Components C6M1 amphipathic peptide complexed with GAPDH siRNA; complexes prepared in water then introduced to PBS and diluted into Opti-MEM for cell treatment.
Size Nm 70.00
Zeta Mv 30.00
Model Scope in_vitro
Model Type in vitro
Cell Lines Or Primary Cells CHO-K1 (Chinese hamster ovary) cells
Animal Model
Administration Route
Output Type In vitro functional RNA effect: GAPDH protein knockdown (western blot)
Output Value ≈72% decrease in GAPDH protein vs untreated (ImageJ quantification) at 50 nM siRNA, MR 30:1; naked siRNA and C6M1+NC-siRNA showed no significant knockdown
Output Units
Output Notes Study focuses on physicochemical characterization (DLS/TEM/CD/serum stability) and demonstrates in vitro functional knockdown in CHO-K1; no in vivo experiments.
