Background: G-CSF

Granulocyte-colony stimulating factor (G-CSF) is a 24-25 kDa monomeric glycoprotein that regulates the proliferation, differentiation, and activation of hematopoietic cells in the neutrophilic granulocyte lineage. Mature human G-CSF is a 178 amino acid (aa) O-glycosylated protein that contains two intrachain disulfide bridges. In humans, alternate splicing generates a second minor isoform with a 3 aa deletion. Mouse and human G-CSF share 76% aa sequence identity, and the two proteins show species cross-reactivity. G-CSF is produced by activated monocytes and macrophages, fibroblasts, endothelial cells, astrocytes, neurons, and bone marrow stroma cells. In addition, various tumor cells express G-CSF constitutively.   

Human G-CSF receptor (G-CSF R) is a 120 kDa type I transmembrane glycoprotein that belongs to the hematopoietin receptor superfamily. The mature protein consists of a 603 aa extracellular domain (ECD), a 23 aa transmembrane segment, and a 186 aa cytoplasmic domain. The ECD contains an N-terminal Ig-like domain, a cytokine receptor homology domain, and three fibronectin type III domains. Alternate splicing of human G-CSF R generates additional isoforms including a potentially soluble form of the receptor. The ECDs of mouse and human G-CSF R share 63% aa sequence identity. G-CSF R forms a complex with the ligand in a 2:2 ratio. It is expressed on monocytes, neutrophils, megakaryocytes, platelets, myeloid progenitors, trophoblasts and placenta, endothelial cells, and various tumor cell types.   

G-CSF is an important regulator for granulopoiesis in vivo, and mutations in G-CSF R are associated with congenital neutropenia. G-CSF can support the growth of multilineage hematopoietic progenitor cells and mobilize them from the bone marrow into the bloodstream. G-CSF enhances the functional capacity of mature neutrophils and supports their survival by limiting the rate of apoptosis. G-CSF also enhances M-CSF induced monocytopoiesis from hematopoietic progenitor cells and stimulates the proliferation of peripheral Th2-inducing dendritic cells (30, 31). It promotes the development of T cell immune tolerance as well as tissue recovery following myocardial infarction and cerebral ischemia.

Assay Procedure


Plate Preparation

  1. Dilute the Capture Antibody to the working concentration in PBS without carrier protein. Immediately coat a 96-well microplate with 100 μL per well of the diluted Capture Antibody. Seal the plate and incubate overnight at room temperature.
  2. Aspirate each well and wash with Wash Buffer, repeating the process two times for a total of three washes. Wash by filling each well with Wash Buffer (400 μL) using a squirt bottle, manifold dispenser, or autowasher. Complete removal of liquid at each step is essential for good performance. After the last wash, remove any remaining Wash Buffer by aspirating or by inverting the plate and blotting it against clean paper towels.
  3. Block plates by adding 300 μL Reagent Diluent to each well. Incubate at room temperature for a minimum of 1 hour.
  4. Repeat the aspiration/wash as in step 2. The plates are now ready for sample addition.

Assay Procedure

  1. Add 100 μL of sample or standards in Reagent Diluent, or an appropriate diluent, per well. Cover with an adhesive strip and incubate 2 hours at room temperature.
  2. Repeat the aspiration/wash as in step 2 of Plate Preparation.
  3. Add 100 μL of the Detection Antibody, diluted in Reagent Diluent with NGS, to each well. Cover with a new adhesive strip and incubate 2 hours at room temperature.
  4. Repeat the aspiration/wash as in step 2 of Plate Preparation.
  5. Add 100 μL of the working dilution of Streptavidin-HRP to each well. Cover the plate and incubate for 20 minutes at room temperature. Avoid placing the plate in direct light.
  6. Repeat the aspiration/wash as in step 2.
  7. Add 100 μL of Substrate Solution to each well. Incubate for 20 minutes at room temperature. Avoid placing the plate in direct light.
  8. Add 50 μL of Stop Solution to each well. Gently tap the plate to ensure thorough mixing.
  9. Determine the optical density of each well immediately, using a microplate reader set to 450 nm. If wavelength correction is available, set to 540 nm or 570 nm. If wavelength correction is not available, subtract readings at 540 nm or 570 nm from the readings at 450 nm. This subtraction will correct for optical imperfections in the plate. Readings made directly at 450 nm without correction may be higher and less accurate.
