Anti-ratConc/Titer: 1:1200-1:2000(FITC)Located in the cell membrane of thyroid cells. NIS can open or close the gates to allow a sodium and iodine flow across the membrane. This antiserum raised in rabbit against the C-terminal of rat NIS (which cross-reacts with human NIS) may be useful for studying thyroid tumor sensitivity to radioactive iodine treatment.
