Description:
Methoxy-X04 is a fluorescent amyloid β (Aβ) probe for the detection and quantification of plaques, tangles and cerebrovascular amyloid with good specificity. It is a derivative of Congo red and Chrysamine-G that contains no acid groups and is therefore smaller and much more lipophilic than Congo red or Chrysamine-G. Methoxy-X04 retains in vitro binding affinity for amyloid beta (Abeta) fibrils (Ki = 26.8 nM) very similar to that of Chrysamine-G. Using multiphoton microscopy to obtain high-resolution (1 microm) fluorescent images from the brains of living PSI/APP mice, individual plaques could be distinguished within 30 to 60 min after a single IV injection or a single IP injection of Methoxy-X04.
