Background
Mouse
granulocyte-colony stimulating factor (G-CSF) is a 24-25 kDa monomeric
glycoprotein that regulates the proliferation, differentiation and activation
of hematopoietic cells. Mouse G-CSF cDNA encodes a 208 amino acid (aa)
precursor protein with a 30 aa signal sequence that is proteolytically cleaved
to form a 178 aa O-glycosylated mature protein containing two intrachain
disulfide bridges. In humans, two distinct cDNA clones, encoding a 204 aa form
and a minor alternatively spliced 207 aa form of G-CSF precursors, have been
isolated. Mouse and human G-CSF are 76% identical at the aa sequence level and
the two proteins show species cross-reactivity. G-CSF is produced primarily by
monocytes and macrophages upon activation by endotoxin, TNF-alpha or IL-1. Other
cell types, including fibroblasts, endothelial cells, astrocytes and bone
marrow stroma cells, can also secrete G-CSF after activation. In addition,
various tumor cells express G-CSF constitutively.
Mouse G-CSF
receptor (G-CSF R) is a 120 kDa, type I transmembrane glycoprotein that belongs
to the hematopoietin receptor superfamily. The mature protein is 812 amino
acids in length and contains a 601 aa extracellular region, a 24 aa
transmembrane segment, and a 187 aa cytoplasmic domain. The extracellular
region contains multiple modules, including an N-terminal Ig-like domain, a
cytokine receptor homology domain, and three fibronectin type III domains.
Based on crystallographic study, G-CSF receptor forms a complex with the ligand
in a 2:2 ratio. Mouse and human G-CSF receptor share 63% aa sequence identity.
Cells known to express G-CSF R include monocytes and neutrophils,
megakaryocytes and platelets, CD34+ CD33+ and CD34+ CD38+ hematopoietic
progenitors, trophoblasts, endothelial cells and various tumor cell types.
G-CSF is an
important regulator for granulopoiesis in vivo. It has been demonstrated that
G-CSF can support the growth of multi-lineage hematopoietic progenitor cells
without influencing their commitment to the myeloid lineage and mobilize
hematopoietic progenitor cells from the bone marrow into the bloodstream. On
mature neutrophils, G-CSF may regulate neutrophil survival by controlling their
rate of apoptosis. G-CSF has also been shown to enhance the functional capacity
of mature neutrophils. As a consequence of its effects on hematopoietic
progenitor cells, G-CSF has been shown to enhance monocytopoiesis in the
presence M-CSF. Within the peripheral blood stem cell population mobilized with
G-CSF, selective increases in the number of T helper 2-inducing dendritic cells
are found.

What is the difference between the Quantikine and Duoset ELISA kits?
- Our Quantikine kits are fully optimized and validated for the sample types listed on the product specific webpage and datasheet, as this can vary between kits. Each kit is supplied ready to use with one pre-coated 96-well plate, a detection antibody directly conjugated to HRP, and all other necessary reagents. These kits are ideal for researchers who want the convenience of a ready to use and optimized ELISA product. Some of these kits are also available prepackaged in larger 6 and 50 plate sizes.Our DuoSet Kits, in contrast, are ELISA development kits containing the capture and detection antibody, the mass-value calibrated standard, and streptavidin-HRP to prepare approximately 5 or 15 plates. Ancillary reagents will need to be used/purchased, and for most kits, we will recommend one of our Ancillary Reagent Kits, which contain the reagents we use ourselves in-house. DuoSet kits are validated only for cell culture supernatant samples and therefore require further development and validation for accurate measurement in more complex samples such as serum and plasma. Our DuoSet Kits offer an economical, flexible alternative for the experienced ELISA user.
