CSF 14-3-3 Western blot




Lanes 1, 2, 3 are positive for CSF 14-3-3

Lanes 4, 5, 6 are weakly positive for CSF 14-3-3

Lanes 7, 8 and 9 are negative for CSF 14-3-3

Lanes 1 and 2 are from two patients with sporadic Creutzfeldt-Jakob disease (CJD)

Lanes 3 and 4 are from patients who have had a stroke

Lanes 5, 6, 7, 8 and 9 contain CSF samples from patients who do not have CJD

In the United Kingdom weakly positive CSF 14-3-3 results are not considered to be supportive of a diagnosis of sporadic CJD.
