To prove our hypothesis that Lcn-2 is present in tumor EC fluids, we analyzed the Lcn-2 protein content in wildtype EC fluids by ELISA (Figure 3i) and quantified Lcn-2-bound iron (Figure 3j) via AAS after the immunoprecipitation of Lcn-2 in EC fluids. The gene discussed is LCN2; the disease is neoplasm.
