HTRF Human IL-6 Detection Kit, 96 Assay Points

Assay principle

Cell supernatant, sample, or standard is dispensed directly into the assay plate for the detection by HTRF® reagents (384-well low-volume white plate or Revvity low-volume 96-well plate in 20 µl). The antibodies labeled with the HTRF donor and acceptor are pre-mixed and added in a single dispensing step, to further streamline the assay procedure. The assay can be run up to a 1536-well format by simply resizing each addition volume proportionally.

Intra-assay (n=24)

Each of the 3 samples was measured 24 times, and % CV was calculated for each sample.

Inter-assay (n=4)

Each of the samples was measured in 4 different experiments, and % CV was calculated for each sample.

Inhibition of IL6 secretion in THP1 cells with JTE607

THP1 cells plated at 100 kcells/well were incubated for 18 h with increasing concentrations of JTE 607 in presence of 2 µg/mL LPS. 16 µL of supernatants were then transferred into a white detection plate (384 low volume) to be analyzed by the Human IL6 Assay.

IL6 secretion in PBMCs stimulated with LPS

PBMC were plated at 50, 100 and 400 kcells/well and stimulated for 18 h with increasing concentrations of LPS ( 0, 0.02, 0.2, 2 µg/mL). 16 µL of supernatants were then transferred into a white detection plate (384 low volume) to be analyzed by the Human IL6 Assay.
