Assay Principle
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 rat SP-C 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)    
1:1000 Average % 85    
Range % 80-90    
1:2000 Average % 104    
Range % 100-109    
1:4000 Average % 91    
Range % 85-96    
1:8000 Average % 96    
Range % 91-103    
The recovery of rat SP-C spiked to levels throughout the range of the assay in various matrices was evaluated. Samples were diluted prior to assay as directed in the Sample Preparation section.

Target Background

(From Uniprot)
Pulmonary surfactant associated proteins promote alveolar stability by lowering the surface tension at the air-liquid interface in the peripheral air spaces.
Gene References into Functions
  1. SP-C is present on the surface of exocytosed surfactant particles. Antibodies against SP-C stabilize the released particles when contacting the air-liquid interface, precluding their transformation and the formation of surface films. SP-C acts as an essential, preformed molecular key in the initial stages of surfactant unpacking and surface film formation. PMID: 27155084
  2. misfolded surfactant protein C has a role in endoplasmic reticulum stress in epithelial-mesenchymal transition of alveolar epithelial cells PMID: 21169555
  3. Results suggest that there is no primary deficiency of surfactant proteins A, B, or C in the nitrofen-induced rat model of congenital diaphragmatic hernia. PMID: 12904592
  4. surfactant protein C processing requires a type II transmembrane topology directed by juxtamembrane positively charged residues PMID: 12933801
  5. NO mediated the decrease in surfactant protein gene expression PMID: 15640287
  6. Data indicate that heparin can be stimulatory to surfactant protein B and C gene expression depending on concentration, degree of sulfation, and surrounding fibroblast growth factor environment. PMID: 16794256
