Rabbit Anti-Human SLC2A3 polyclonal antibody for IHC-P. Glucose is fundamental to the metabolism of mammalian cells. Several glucose transporter protein (Glut) isoforms have been identified and shown to function in response to insulin and IGF-1 induced signaling. GLUT-3 is detectable in a few normal cell type spermatids in testis with active spermatogenesis, placental trophoblast membranes, and neurons in brain. GLUT-3 staining is also detectable in human cancers including those of the ovary, lung, and testis.
