Revvity, 64FCRNPET, HTRF FcRn Binding kit, 100 Assay Points

Overview
The neonatal Fc receptor is an Fc receptor found in the placenta. It displays the unique feature of facilitating IgG transport from the mother to the growing fetus. This receptor also has an important role in modulating IgG and albumin half-life in the bloodstream, influencing the pharmacokinetic parameters through an FcRn-mediated transcytosis process. The FcRn kit measures the binding between Fc-based molecules and the FcRn receptor.
HTRF assays offer many advantages over other technologies:

Homogeneous add-and-read format
No wash steps
Low background
Straightforward miniaturization from 96- or 384-well microplates to high density assay formats such as 384-well low volume and 1536-well plates
Stable signal, providing flexibility in time of readout or size of assays
How it works
Assay principle
The FcRn receptor biochemical binding assay is a competitive assay involving the extracellular ectodomain of FcRn that is biotinylated and bound to Terbium cryptate-labeled Streptavidin, and human IgG1 labelled with d2. The unlabeled antibody or Fc fused drug competes with the d2 labelled IgG1 for binding to the receptor, resulting in a decrease in FRET signal.

 

Assay protocol
The FcRn biochemical binding assay needs only 1 incubation step after reagent distribution. Terbium Cryptate pre-labelled FcRn ectodomain is dispensed, followed by the addition of the sample and IgG1 labelled with d2. After 2h of incubation at RT, the signal can be read.
