Product information
Overview
Also known as CSF2 (colony-stimulating factor 2), GM-CSF (granulocyte-macrophage colony-stimulating factor) is a hematopoietic growth factor and an immune modulator. Under immune stimuli, it is produced by T lymphocytes, macrophages, endolial cells, and fibroblasts. It acts on precursor cells in bone marrow to initiate ir proliferation and differentiation into mature granulocytes and macrophages. GM-CSF stimulates multipotent progenitor cells.
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.

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 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.
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.

Assay validation
GM-CSF secretion by PBMC co-stimulated with ionomycin and PMA
PBMCs, plated at 100,000 cells/well in a 96 well plate, were stimulated for 24h with 1µg/ml of ionomycin and with various concentrations of PMA. 16µl of supernatant were transferred into a 384 well (small volume) white detection plate to be analyzed by the Human GM-CSF Assay.
