Methods Used

• Preparation of washing solution (0.5% Tween 20 in PBS).
• Preparation of blocking solution (3% Blocker A in PBS).
• Filtration sterilization of the blocking solution.
• Preparation of assay diluent solution (1% Blocker A in PBS).

Main Results

• ECLIA provides fast and sensitive quantification of MeCP2.
• Low intra- and inter-assay error observed.
• Wide working range for accurate measurements.
• Protocol is straightforward and user-friendly.

Conclusions
