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 AQP-5 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

Target Data

Function Forms a water-specific channel. Implicated in the generation of saliva, tears, and pulmonary secretions. Required for TRPV4 activation by hypotonicity. Together with TRPV4, controls regulatory volume decrease in salivary epithelial cells.
