Also known as CSF3 (colony-stimulating factor 3), G-CSF is a hematopoietic cytokine. It acts on precursor cells in bone marrow to initiate ir proliferation and differentiation into mature granulocytes, on hematopoietic stem cells to induce ir mobilization in blood stream, and on neurons to promote neurogenesis and block apoptosis. In myocardial infarction or ischemia, G-CSF promotes T cells' immune tolerance and tissue recovery. absence of a functional G-CSF receptor is associated with congenital neutropenia.
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.

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.
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. To fully understand how to deal with HTRF data processing and also 4PL 1/y² fitting. Revvity also worked with Myassays.com to help you in your data analysis.
