New technologies in molecular allergodiagnostics.

The article presents the characteristics of the ALEX2 (MacroArrayDX, Wien, Austria). It is designed for simultaneous detection of IgE total and specific IgE-aB to 120 extracts and 180 molecules by solid-phase enzyme immunoassay. Extracts and allergen molecules combined with nano-particles are sorbed on a solid-phase substrate, forming a macroscopic multiplex matrix - the immune allergy chip.
