The protein is a homo- or heterodimer consisting of two subunits, alpha and beta.
Astroglial cells are the most common cells in brain tissue.
They build up a three-dimensional network which constitutes a supporting framework for neurones. The S-100 amino acid sequence is well preserved between different species suggesting an important but still unsettled physiologic role. Sangtec 100 is thereby highly suitable for detecting cellular injury in the brain. When a brain lesion occurs S-100 is released into both the CSF and the blood. This has been demonstrated in patients suffering from stroke, subarachnoid haemorrhage as well as minor and severe head injury.
