Precision
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.      
               
Linearity
To assess the linearity of the assay, samples were spiked with high concentrations of mouse MASP2 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

Target Background

Function
(From Uniprot)
Serum protease that plays an important role in the activation of the complement system via mannose-binding lectin. After activation by auto-catalytic cleavage it cleaves C2 and C4, leading to their activation and to the formation of C3 convertase.
Gene References into Functions
  1. MASP-2 has an essential role in the mediation of cerebral ischemia-reperfusion injury. PMID: 27577570
  2. this study shows that MASP-2 contributes to the development of collagen Ab-induced arthritis PMID: 28739878
  3. We induced anti-myeloperoxidase vasculitis in mice and showed that neither MASP-2- nor properdin-deficient mice were protected, suggesting that alternative pathway activation does not require properdin or the lectin pathway. PMID: 27235854
  4. Mannan-binding lectin-associated serine protease 2 is critical for the development of renal ischemia reperfusion injury and mediates tissue injury in the absence of complement C4. PMID: 24868011
  5. Gene targeting of mouse TDP-43 negatively affects Masp2 expression. PMID: 24740308
  6. ALI in H5N1-infected mice was caused by excessive complement activation, as demonstrated by deposition of C3, C5b-9, and MBL-C in lung tissue, and by up-regulation of MBL-associated serine protease-2 and the complement receptors C3aR and C5aR. PMID: 23526211
  7. study corroborates the essential function of MASP-2 in the lectin pathway and highlights the importance of mannan-binding lectin-independent lectin pathway activation in the host defense against pneumococci PMID: 22792067
  8. Targeting of mannan-binding lectin-associated serine protease-2 confers protection from myocardial and gastrointestinal ischemia/reperfusion injury. PMID: 21502512
  9. Highly conserved intron sequences. Restricted expression contrasts with the ubiquitous expression of neighboring genes. PMID: 15672593
  10. Recombinant protein of masp2 was made and purified. PMID: 15826378
  11. MASP-2 is essential for the activation of C4 and sMAP plays a regulatory role in the activation of the lectin pathway. PMID: 17142762
