Intra-assay Precision (Precision within an assay): CV%<8%        
Three samples of known concentration were tested twenty times on one plate to assess.    
Inter-assay Precision (Precision between assays): CV%<10%        
Three samples of known concentration were tested in twenty assays to assess.      
To assess the linearity of the assay, samples were spiked with high concentrations of mouse GPI in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.  
  Sample Serum(n=4)    
1:1 Average % 95    
Range % 90-99    
1:2 Average % 94    
Range % 87-98    
1:4 Average % 100

Target Background

(From Uniprot)
Besides it's role as a glycolytic enzyme, mammalian GPI can function as a tumor-secreted cytokine and an angiogenic factor (AMF) that stimulates endothelial cell motility. GPI is also a neurotrophic factor (Neuroleukin) for spinal and sensory neurons.
Gene References into Functions
  1. PGI is a moonlighting protein that functions as a cytosolic enzyme involved in glycolysis and gluconeogenesis, and as cytokine through binding to its cell surface receptor. PMID: 8674049
  2. The mGPI-transgenic mice presented GPI more efficiently and showed a dramatic increase in negative selection and an inhibition of arthritis. PMID: 23840022
  3. Data show that silencing of AMF/PGI induced MET and suppressed the tumor growth and pulmonary metastasis of LM8 cells in nude mice. PMID: 20978190
  4. induces hyperpermeability of endothelial and mesothelial cells leading to accumulation of ascites fluid (tumor autocrine motility factor) PMID: 12054583
  5. acid-induced conformational changes in phosphoglucose isomerase result in its increased cell surface association and deposition on fibronectin fibrils PMID: 12888574
  6. Gpi1 immunoreactivity was found in ganglion, amacrine, horizontal and bipolar cells, but not in rods, cones, pigment epithelium and Muller cells. PMID: 15182299
  7. High-resolution crystal structures of the enzyme from mouse have been determined in native form and in complex with the inhibitor erythrose 4-phosphate, and with the substrate glucose 6-phosphate. PMID: 15342241
  8. crystal structure of Autocrine Motility Factor PMID: 15502335
  9. AMF expression significantly contributes to the aggressive phenotype of pancreatic cancer PMID: 15570012
  10. Results report the first high-resolution crystal structure of the inhibitor-free form and the eight types of inhibitor complexes of mouse autocrine motility factor. PMID: 16375918
  11. the receptor molecule for AMF/NLK/MF in leukemic differentiation is not gp78 PMID: 17071500
