A representative Western blot analysis of EL protein abundance. Positive control lane (+) contained the commercial EL standard product, which was used to normalize the signal response across all gels. (A), The abundance of EL protein on urine samples; (B), EL abundance on cancer tissue samples and matching noncancerous samples from gastric cancer patients with no treatment. The β-actin serves as an internal loading control for estimating the relative protein abundance levels; (C), EL protein abundance in serum samples.
