Background Information

CA9(Carbonic anhydrase 9) may be involved in the control of cell proliferation and transformation and appears to be a novel specific biomarker for a cervical neoplasia(PMID:18703501).It is a tumor-associated antigen that has been shown to have diagnostic utility in identifying cervical dysplasia and carcinoma.The protein is presentboth on the plasma membrane and in the nucleus of cells and has the molecular.It was observed the 54KDa and 58 Kda bands in A549.
