By consistently using the stable and species-specific actin antibody as my loading control, I ensure accurate protein analysis in Western blotting, allowing me to confidently investigate protein stability, interactions, and expression levels in my research. The reliable detection of actin in each experiment validates equal protein loading, enabling meaningful comparisons across different samples and experimental conditions. This systematic approach ensures the robustness of my findings and enhances the overall reliability of my Western blot data.

Experimental Design and Results Summary

Applications

Western blot

Sample

Cell extract

Primary Incubation

1:10000 in blocking buffer (5% milk in TBST) for 16 hr at 4 degrees C

Blocking Agent

5% milk in TBST

Secondary Incubation

Goat anti-mouse IgG HRP at 1:5000 dilution in blocking agent for 1 hr at room temperature.

Results Summary

Having consistent actin expression across different samples on the blot confirms the successful use of actin as a loading control in my Western blot experiments. This ensures equal protein loading in each lane, providing a reliable foundation for comparing and analyzing the stability, interactions, and expression levels of target proteins under various experimental conditions. The uniform actin bands empower me to confidently normalize my data, enabling meaningful and accurate conclusions to be drawn from my research findings.
