This video demonstrates a protocol for detecting serum-specific immunoglobulin E using a microfluidic cartridge-based chemiluminescence system. Serum IgEs interact with distinct allergens immobilized in the reaction zone of the cartridge, which are subsequently detected with peroxidase-conjugated anti-IgE antibodies and a chemiluminescent substrate, allowing simultaneous detection of multiple allergen-specific IgEs.

Protocol

All procedures involving sample collection have been performed in accordance with the institute's IRB guidelines. 1. Basic information of the study group NOTE: The Allergy Information Repository of the State Key Laboratory of Respiratory Disease (AIR-SKLRD) is a large serum bank established inside the Guangzhou Institute of Respiratory Hospital (GIRH). Initiated in the last decade, the AIR-SKLRD has already started collecting and …
