R&D Systems now offers a human Progranulin Quantikine ELISA Kit (Catalog # DPGRN0 ). Progranulin is a ubiquitously expressed, secreted glycoprotein involved in the regulation of cell proliferation, differentiation, and development. It is also associated with pathological processes including tumorigenesis in breast cancer, clear cell renal carcinoma, invasive ovarian carcinoma, glioblastoma, adipocyte teratoma, and multiple myeloma. The Quantikine ELISA is designed to measure human Progranulin in cell culture supernatants, serum, plasma, saliva, urine, and milk. <table border="0" cellspacing="1" cellpadding="3" style="border: solid thin #0f4b8c;"> <tr> <td><img src="/f_img/RSD/6163.jpg"></td> </tr> <tr> <td style="font-family:verdana;font-size:12px;"><strong>Assessment of the Levels of Progranulin in Cell Culture Supernatants</strong> Aliquots of cell culture supernatants from human MCF-7 breast cancer cells, MCF-10A mammary epithelial cells, A549 lung cancer cells, ME-180 cervix cancer cells, PC3 prostate cancer cells, or OVCAR-3 ovarian cancer cells were assayed for Progranulin using the human Progranulin Quantikine ELISA Kit (Catalog # DPGRN0).</td> </tr> </table>
