Description

Description
MW = 29.1 kDa. Full length Carbonic Anhydrase II (Carbonate dehydratase II, Carbonic anhydrase C) cloned from human cDNA and expressed in E.coli. The protein consist of the human Carbonic Anhydrase II with a mutation Ser2Ala. (Swiss prot accession: P00918). Mass spectrometry (MALDI) showed that the first aminoacid (Met) is processed during the expression.

Purity
> 95% by SDS-PAGE. The protein is observed, in denaturing conditions, as a single band migrating at molecular weight at about 30.0 kDa.

Supplied as
2 mg/mL in Tris buffer 20mM pH 7.5, NaCl 150mM. The concentration is calculated by the analysis of the absorbance at 280 nm (ε280 = 54000 M-1cm-1).

Characteristics
Under the above described conditions, the product can be concentrated up to 1 mM.

Storage
-20°C. The protein is stable at 4°C for weeks and at 25°C for days. Avoid repeated freeze/thaw cycles.
