MagArray has developed a simple, ultra-sensitive, multiplex immunoassay system. Incorporating a novel magneto-nanoparticle technology derived from the disk drive industry, MagArray biosensors provide numerous advantages over conventional immunoassay systems. A featured application is APIFINY® PRO, the only cancer specific, non-PSA blood test that may aid clinicians in deciding to perform an initial or repeat biopsy by providing insight into a patient’s risk for aggressive prostate cancer.
