The CD32b receptor negatively modulates the Antibody-Dependent Cell-Phagocytosis (ADCP) pathway. This assay, based on our innovative Tag-lite technology, can easily be automated to create a high-throughput solution for predicting ADCP.\u003cbr\u003e\nHTRF assays offer many advantages over other technologies:\u003c\/p\u003e\n\n\u003cp\u003eHomogeneous add-and-read format\u003cbr\u003e\nNo wash steps\u003cbr\u003e\nLow background\u003cbr\u003e\nStraightforward miniaturization from 96- or 384-well microplates to high density assay formats such as 384-well low volume and 1536-well plates\u003cbr\u003e\nStable signal, providing flexibility in time of readout or size of assays\u003cbr\u003e\nHow it works\u003cbr\u003e\nAssay principle\u003cbr\u003e\nThe CD32b receptor cellular binding assay is a competitive assay involving HEK293 cells expressing a specific CD32b variant conjugated to Lumi4-terbium Cryptate, and human IgG1 labelled with d2. The unlabeled antibody or Fc tagged drug competes with the d2 labelled IgG1 for binding to the receptor, resulting in a decrease of FRET signal.\u003c\/p\u003e\n\n\n\n\n  \u003cbr\u003e\n        \n\n\n\t\u003cbr\u003e\n  \u003cbr\u003e\n        \u003cbr\u003e\n  \n\n      \u003cbr\u003e\n  \u003cbr\u003e\n  \u003cbr\u003e\n    \u003cbr\u003e\n      \u003cbr\u003e\n        \u003cbr\u003e\n        \u003cbr\u003e\n        \u003cbr\u003e\n        \u003cbr\u003e\n      \u003cbr\u003e\n    \n\n    \u003cbr\u003e\n      \n\n      \u003cbr\u003e\n        \n\n      \u003cbr\u003e\n    \n\n  \n\n\n\n\n\n\n\n\n\u003cp\u003eAssay protocol\u003cbr\u003e\nThe CD32b receptor cellular binding assays (FcgIIb) present only 1 incubation step after reagents distribution. Lumi4-terbium Cryptate pre-labelled cells are dispensed, followed by the addition of IgG1 labelled with d2 and the sample. After 2h incubation at RT, the signal can be read.
