Antibodies Applications

Source of Antigen





The antibody was raised in rabbits by immunization with the recombinant Human Fetuin-B.

Amino Acid Sequence

MW: 41.8 kDa (calculated), migrates at ~ 55 kDa on SDS-PAGE; N-terminal linker (4 extra AA), C-terminal His-tag (6 extra AA).


Species Reactivity

Human. Not yet tested in other species.

Purification Method

Immunoaffinity chromatography on a column with immobilized recombinant Human Fetuin-B.

Antibody Content

0.1 mg (determined by BCA method, BSA was used as a standard)


The antibody is lyophilized in 0.05 M phosphate buffer, 0.1 M NaCl, pH 7.2. 


Add 0.2 ml of deionized water and let the lyophilized pellet dissolve completely. Slight turbidity may occur after reconstitution, which does not affect activity of the antibody. In this case clarify the solution by centrifugation.


At ambient temperature. Upon receipt, store the product at the temperature recommended below.


The lyophilized antibody remains stable and fully active until the expiry date when stored at -20°C. Aliquot the product after reconstitution to avoid repeated freezing/thawing cycles and store frozen at -80°C. Reconstituted antibody can be stored at 4°C for a limited period of time; it does not show decline in activity after one week at 4°C.

Quality Control Test

Indirect ELISA – to determine titer of the antibody SDS PAGE – to determine purity of the antibody BCA - to determine quantity of the antibody


This product is for research use only.


Research topic

Bone and cartilage metabolism, Energy metabolism and body weight regulation, Immune Response, Infection and Inflammation, Oncology, Others


Fetuin B is a member of cystatin superfamily proteins, comprises two cystatin domains. It was found in secreted form in serum, it is expressed in liver, tongue and placenta. It regulates osteogenesis by inhibition effect on mineralization. It plays a role in oocyte maturation.
