Cell-ID™ IdU, 100 µL—300 Tests

IdU (5-Iodo-2′-deoxyuridine) contains pyrimidine nucleoside that is recognized as a thymidine substitute in DNA synthesis. IdU incorporates into DNA of proliferating cells and is a marker of S phase of the cell cycle. Since IdU incorporation can be measured directly in S phase cells, the need for an antibody or DNA denaturation can be bypassed. Cell-ID 127 IdU is ideally detected in the 127I (iodine) channel of the CyTOF mass cytometer.
