Characteristics: Purified recombinant Human Carbonic anhydrase II protein
Expression System: E.coli
Bioactivity: Specific activity is 50-70 nmoles/min/µg and was obtained by measuring the increase in the amount of p-nitropheno by its esterase activity. Specific activity is defined as the amount of p-nitrophenol that 1ug of enzyme can reduce at 25 °C for 1 minute.
Molecular weight on SDS-PAGE will appear higher.

Purity: > 95 % pure

Application Details

Application Notes: Carbonic anhydrase II protein has been used in SDS PAGE and may be suitable for use in other assays to be determined by the end user.

Assay Procedure:

1. Prepare assay buffer into a suitable container: The final concentrations are 12.5 mM Tris, 75 mM NaCl, pH 7.5.
   2. Dilute 4-Nitrophenyl-Acetate(4-NPA) to 2 mM in Assay Buffer.
   3. Dilute recombinant CA2 protein with various concentrations (1 µg, 1 µg, 1 µg) in 50 µL assay buffer.
   4. Load 50 uL of 2 mM 4-NPA into diluted recombinant CA2 solutions, and start the reaction by adding 50 uL of 2 mM Substrate.
   5. Read at a wavelength of 405 nm (bottom read) in kinetic mode for 5 minutes.

Restrictions: For Research Use only

Background: Carbonic anhydrase 2 (CA2) is one of fourteen forms of human alpha carbonic anhydrases. Carbonic anhydrase catalyzes reversible hydration of carbon dioxide. CA2 is a cytosolic enzyme with the highest activity among all known CAs. Mutations in the CA2 gene result in the CA2 deficiency syndrome, an autosomal recessive disorder that produces osteopetrosis, renal tubular acidosis and cerebral calcification. Recombinant human CA2 was expressed in E. coli and purified by using conventional chromatography.
