Target Details This protein is an inflammatory chemokine that belongs to the CXC chemokine family. This chemokine is produced concomitantly with interleukin-8 (IL8) in response to stimulation with either interleukin-1 (IL1) or tumor necrosis factor-alpha (TNFA). This chemokine is a potent chemotaxin involved in neutrophil activation.

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 human ENA-78/CXCL5 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 % 98    
Range % 94-103    
1:2 Average % 102    
Range % 97-105    
1:4 Average % 86
