Gel Electrophoresis Image - DNA/Protein Separation Analysis #3870222 (License: Personal Use)

This grayscale image displays a typical gel electrophoresis result with four sample lanes. Lane 1 shows a ladder with evenly spaced bands for size calibration; lane 2 contains a faint discrete band; lane 3 exhibits a thick, diffuse smear suggesting degraded nucleic acid or overloading; lane 4 shows two sharp bands likely representing purified fragments. The contrast and band clarity indicate proper staining and imaging conditions.

Used in molecular biology labs and educational resources to demonstrate nucleic acid or protein separation techniques; supports protocols for PCR verification, restriction digest analysis, or Western blot validation. Matches user intent for visual reference, troubleshooting, or teaching material.
