Figure 1From: Polysialic Acid Neural Cell Adhesion Molecule (PSA-NCAM) is an adverse prognosis factor in glioblastoma, and regulates olig2 expression in glioma cell lines Standard curve of PSA-NCAM ELISA. (A) Increasing amounts of purified PSA-NCAM from P0 mouse brains were detected by the developed ELISA. Data are presented as mean +/- standard deviation of duplicate measurements. (B) ELISA test on serial dilutions of TE671 extract expressing PSA-NCAM or treated with endoN.Back to article page
