Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Lead Time
Basically, we can dispatch the products out in 1-3 working days after receiving your orders. Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.

Target Background

Reversible hydration of carbon dioxide. Can hydrates cyanamide to urea.
Gene References into Functions
  1. Anti-CA I and II antibody levels were investigated using ELISA in serum samples from 30 patients with Acute Myeloid Leukemia (AML) and 30 healthy peers. Anti-CA I and II antibody titers in the AML group were significantly higher compared with the control group (p=0.0001 and 0.018, respectively). PMID: 28270370
  2. These six-membered carbocycles showed nice inhibitory action against AChE and human carbonic anhydrase (hCA) II and I isoforms. The hCA I, II, and AChE were efficiently inhibited by these molecules, with Ki values in the range of 6.70-35.85 nM for hCA I, 18.77-60.84 nM for hCA II, and 0.74-4.60 for AChE, respectively PMID: 28613396
  3. These results showed that flavonoids especially malvin and oenin effectively inhibited hCA I and II isoenzymes. PMID: 28445001
  4. Discovery of potent carbonic anhydrase, acetylcholinesterase, and butyrylcholinesterase enzymes inhibitors: The new amides and thiazolidine-4-ones synthesized on an acetophenone base. PMID: 28544359

  8. We demonstrated that resveratrol, caffeic acid, and tannic acid in stored blood could decrease the sensitivity to oxidation of erythrocytes in vitro but did not exhibit such effects on Carbonic Anhydrase activity. PMID: 27413740
  9. CA1 is a potential oncogene and that it contributes to abnormal cell calcification, apoptosis and migration in breast cancer. PMID: 26459317
  10. We report on the competitive zinc metalation of apo-carbonic anhydrase [CA; metal-free CA (apo-CA)] in the presence of apo-metallothionein 1A domain fragments to identify domain specific determinants of zinc binding and zinc donation PMID: 26475450
  11. The gene encoding CA1 is susceptible to ankylosing spondylitis and plays a role in the process of bone formation. PMID: 22838845
  12. Structure-activity relationships study showed that indolylchalcone derivatives have higher inhibitory activities than pyrido[2,3-d]pyrimidine derivatives on hCA I and hCA II. PMID: 25165709
  13. Myocardial carbonic anhydrase 1/2 activation is significantly elevated in diabetic ischemic cardiomyopathy. PMID: 24670789

  15. The new prognostic biomarkers GRP78, Fructose-bisphosphate Aldolase A (ALDOA), Carbonic Anhydrase I (CA1) and Peptidyl-prolyl cis-trans isomerase A or Cyclophilin A (PPIA)) provided good survival prediction for TNM stage I-IV patients. PMID: 22996014
  16. A significant correlation was found between positive carbonic anhydrase I staining and oral squamous cell carcinoma for more advanced clinical stage and larger tumor size, but not for positive lymph node metastasis, distal metastasis, and recurrence. PMID: 22416960
  17. carbonic anhydrase I, phosphoglycerate kinase 1 and apolipoprotein A-I appeared to be the most significant variations of proteins in patients with osteopenia and osteoarthritis PMID: 22619369
  18. A protein encoded by this locus was found to be differentially expressed in postmortem brains from patients with atypical frontotemporal lobar degeneration. PMID: 22360420
  19. Overexpression of CA1 in the synovial tissues of ankylosing spondylitis (AS) patients may promote improper calcification and bone resorption in AS. PMID: 21143847
  20. single mutation of an amino acid not considered essential to catalysis (Phe91Asn) in carbonic anhydrase I, but is near substrate binding pocket, led to increase of catalytic activity; mutant CA I also showed higher affinity for sulfonamide inhibitors PMID: 20624682
  21. The X-ray crystallographic structure of the CA I Michigan 1 variant isozyme is reported, both in the presence and absence of a second bound zinc ion coordinated to His 64, His 200, and Arg 67. PMID: 12009884
