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 CA3 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

Target Background

(From Uniprot)
Reversible hydration of carbon dioxide.
Gene References into Functions
  1. CAIII and Hsp70 expressions were higher in LPRD patients that in non-LPRD patients, suggesting the possibility as one of biomomarker in LPRD diagnosis. PMID: 26847302
  2. this study detected the formation and colocalization of 6-nitrotryptophan-containing proteins and CAIII in the skin of atopic dermatitis patients, not only in the lesional part but also in the nonlesional part, through histochemical analyses PMID: 24838180
  3. Report that anti-CAIII antibodies may be useful for diagnosing microscopic polyangiitis. PMID: 23981757
  4. The carbonic anhydrase CA3 isoform displayed an increased abundance during muscle aging, which was independently verified by immunoblotting of differently aged human skeletal muscle samples. PMID: 22797148
  5. The generation of CA III and IV autoantibodies, antioxidant enzymes, and cytokines might influence each other. PMID: 23049597
  6. Crystallization and preliminary X-ray analysis of human carbonic anhydrase III PMID: 11976500
  7. Data show that inserting histidine residues into the active site cavity of carbonic anhydrase II or III results in rates of proton transfer to the zinc-bound hydroxide that are antagonistic or suppressive with respect to the corresponding single mutants. PMID: 12171926
  8. Proton transfer within the active-site cavity of carbonic anhydrase III PMID: 12484342
  9. myoglobin/carbonic anhydrase III ratio in the blood proved to be a more specific indicator for myocardial damage than myoglobin alone after myocardial infarction. PMID: 12745799
  10. CAIII expression is upregulated in kidney cortex samples from the end-stage kidney of a patient with Dent's disease owing to the G506E mutation of CLCN5 PMID: 18322545
  11. CAIII promotes transformation and invasion capability in hepatoma cells through FAK signaling pathway. PMID: 18444244
  12. The level of CAIII is specifically insufficient in the skeletal muscle of myasthenia gravis patients. PMID: 19301202
