Sheep anti Human carbonic anhydrase II antibody recognizes human carbonic anhydrase II, also known as Carbonate dehydratase II or Carbonic anhydrase C. Carbonic anhydrase II is a 259 amino acid ~30 kDa enzyme essential for bone resorption and osteoclast differrentiation.

Mutations in the CA2 gene has been identified as the cause of osteopetrosis, autosomal recessive 3 (OPTB3), a rare disease characterized by particularly dense bone, cerebral calcification and renal tubular acidosis (Shah et al 2004).

Product identity is confirmed by double diffusion vs human CAII. No reactivity is seen in immunodiffusion against CAI.

Target Species
Product Form

Antiserum Preparation
Antisera to human carbonic anhydrase II were raised by repeated immunisation of sheep with highly purified antigen. Purified IgG was prepared from whole serum by ion exchange chromatography.
Buffer Solution
Glycine buffered saline
Preservative Stabilisers
<0.1% Sodium Azide (NaN3)
0.1% EACA
0.01% Benzamidine
Purified human carbonic anhydrase II (CAII) prepared from erythrocytes.

This product is shipped at ambient temperature. It is recommended to aliquot and store at -20°C on receipt. When thawed, aliquot the sample as needed. Keep aliquots at 2-8°C for short term use (up to 4 weeks) and store the remaining aliquots at -20°C.

Avoid repeated freezing and thawing as this may denature the antibody. Storage in frost-free freezers is not recommended.

This product has been reported to work in the following applications. This information is derived from testing within our laboratories, peer-reviewed publications or personal communications from the originators.
