- SynonymCA14,CA-XIV
- SourceHuman Carbonic Anhydrase XIV, His Tag (CA4-H5227) is expressed from human 293 cells (HEK293). It contains AA Ala 16 - Met 290 (Accession # AAH34412).Predicted N-terminus: Ala 16Request for sequence
- Molecular Characterization
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 31.8 kDa. The protein migrates as 45-50 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
- EndotoxinLess than 1.0 EU per μg by the LAL method.
- Purity
>95% as determined by SDS-PAGE.
- Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

Human Carbonic Anhydrase XIV, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.
- BackgroundCarbonic anhydrase XIV (CA14),a member of the alpha-carbonic anhydrase family, is also known as carbonate dehydratase XIV, which is a single-pass type I membrane protein. Carbonic anhydrases (CAs) are a large family of zinc metalloenzymes that catalyze the reversible hydration of carbon dioxide. CA14 shares highest sequence similarity with the other transmembrane CA isoform, CA XII; however, they have different patterns of tissue-specific expression and thus may play different physiologic roles. As for tissue specificity,CA14 is high expressed in all parts of the central nervous system and lower expressed in adult liver, heart, small intestine, colon, kidney, urinary bladder and skeletal muscle.
