Revvity, 62HIFNAPEG, HTRF Human IFN-α Detection Kit, 500 Assay Points

Overview
Mainly produced by leukocytes, IFN alpha is involved in innate immunity response to viral infection. IFN alpha activates several intracellular pathways in target cells, which explains its pleiotropic effects on cell differentiation, growth, and immunoregulation.
Assessment of serum samples often requires enhanced sensitivity. In some cases, AlphaLISA assays may have sufficient sensitivity to enable detection of low levels of analytes in serum or plasma.
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
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 Cisbio 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.

Assay data analysis
The 4 Parameter Logistic (4PL) curve is commonly recommended for fitting an ELISA standard curve. This regression enables the accurate measurement of an unknown sample across a wider range of concentrations than linear analysis, making it ideally suited to the analysis of biological systems like cytokine releases.
