Intra-assay Precision (Precision within an assay) Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision.

Inter-assay Precision (Precision between assays) Three samples of known concentration were tested six times on one plate to assess intra-assay precision.

スパイク回収

The spike recovery was evaluated by spiking 3 levels of human G-CSF into health human serum sample. The un-spiked serum was used as blank in this experiment.
The recovery ranged from 80% to 119% with an overall mean recovery of 101%.

機能

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. It promotes the development of T cell immune tolerance as well as tissue recovery following myocardial infarction and cerebral ischemia.
