Fig. 1From: Prognostic impact of CXCL16 and CXCR6 in non-small cell lung cancer: combined high CXCL16 expression in tumor stroma and cancer cells yields improved survivalAntibody validation. In the lung adenocarcinoma cell line A549 we detected protein bands corresponding to CXCL16 and CXCR6. Transfection with specific siRNAs caused a marked decrease of protein expression. Equal loading was ensured by staining for beta-actinBack to article page
