Mouse anti-CD71, clone MRQ-48 - 7 ml

CD71, also known as transferrin receptor, is a membrane glycoprotein that mediates the uptake of iron from transferrin for hemoglobin synthesis in erythroid cells. Early erythroid precursors and erythroblasts contain the highest mass of transferrin receptors, and expression is lost as these cells cease hemoglobin synthesis and mature into erythrocytes. Therefore, anti-CD71 is a useful marker for highlighting erythroid precursors in bone marrow specimens. Increased CD71 expression is also associated with active cell growth including neoplastic tumor growth and may be seen in various carcinomas such as thyroid carcinomas, lung carcinomas, breast carcinomas, hepatocellular carcinomas and colorectal carcinomas.
