Fetuin-B Human Recombinant produced in HEK cells is a single, glycosylated, polypeptide chain containing a total of 377 amino acids, having a molecular mass of 41.8kDa (calculated) though it migrates at approximately 55kDa on SDS PAGE, the Fetuin-B is also composed of a 4 a.a N-terminal linker and fused to a 6 a.a His tag at C-Terminus.The Human FETUB is purified by proprietary chromatographic techniques.
Fetuin-B (FETUB) belongs to the fetuin family, part of the cystatin superfamily proteins and comprised of 2 cystatin domains. Fetuin-B is found in a secreted form in the serum, it is expressed in the liver, tongue and placenta. FETUB regulates osteogenesis by inhibition effect on mineralization. Fetuins are implicated in a number of various functions, including osteogenesis and bone resorption, regulation of the insulin and hepatocyte growth factor receptors, and response to systemic inflammation. FETUB also has a role in oocyte maturation. Fetuin-B is essential in preventing premature zona pellucida hardening before fertilization, probably by inhibiting the protease activity of ASTL, which is a protease that mediates the cleavage of ZP2 and triggers zona pellucida hardening.
It is recommended to add deionized water to a working concentration of 0.5mg/ml and let the lyophilized pellet dissolve completely. FETUB is not sterile! Please filter the product by an appropriate sterile filter before using it in the cell culture.
