Figure 4From: CSE1L, a Novel Microvesicle Membrane Protein, Mediates Ras-Triggered Microvesicle Generation and Metastasis of Tumor CellsPresence of phosphorylated CSE1L in sera from cancer patients. (A) Serum threonine-phosphorylated CSE1L analyzed by immunoprecipitation with agarose-conjugated anti-phosphothreonine antibodies and a pool of sera from 36 colorectal cancer patients (each 10 µL) or 36 healthy donors (each 10 µL) and immuno-blotting with anti-CSE1L antibodies. Control immunoprecipitation was performed using agarose-conjugated normal mouse IgG. (B) The levels of CSE1L in the pools of cancer sera (n = 36) and normal sera (n = 36) were analyzed by immunoblotting with anti-CSE1L antibodies (clone 24).Back to article page
