背景資料: Fetuin is a liver-produced negative acute phase protein composed of two subunits， the A and B chains.
Fetuin homologs have been identified in several species including rat， sheep， pig， rabbit， guinea pig， cattle， mouse and human. Multiple physiological roles for these homologs have been suggested， including ability to bind to hydroxyapatite crystals and to specifically inhibit the tyrosine kinase （TK） activity of the insulin receptor （IR）.
Fetuin-A （alpha2-Heremans-Schmid glycoprotein； AHSG） is an important circulating inhibitor of calcification in vivo， and is downregulated during the acute-phase response.
Sera from patients on long-term dialysis with low AHSG concentrations showed impaired ex-vivo capacity to inhibit CaxPO4 precipitation.
Fetuin may influence the resolution of inflammation by modulating the phagocytosis of apoptotic cells by macrophages.
ASHG blocks TGF-beta-dependent signaling in osteoblastic cells， and mice lacking ASHG display growth plate defects， increased bone formation with age， and enhanced cytokine-dependent osteogenesis.

溶解建議: Filtered White lyophilized （freeze-dried） powder. Filtered （0.4um） and lyophilized from 0.5 mg/ml in PBS pH 7.4. It is recommended to add deionized water to prepare a working stock solution of approximately 0.5mg/ml and let the lyophilized pellet dissolve completely. Product is not sterile! Please filter the product by an appropriate sterile filter before using it in the cell culture.

保存建議: Store the lyophilized protein at -20℃. Aliquot the product after reconstitution to avoid repeated freezing/thawing cycles. Reconstituted protein can be stored at 4℃ for a limited period of time； it does not show any change after two weeks at 4℃. The lyophilized protein remains stable until the expiry date when stored at -20℃.

其他: ProSpec 是一家全球著名細(xì)胞因子蛋白生產(chǎn)和研發(fā)的公司，具有20多年的生產(chǎn)經(jīng)驗(yàn)，專注于蛋白（重組及合成）生產(chǎn)研發(fā)。我們的核心產(chǎn)品包括：干擾素、白介素、骨蛋白、腫瘤壞死因子、成纖維生長(zhǎng)因子、瘦素、干細(xì)胞因子、催乳素、表皮生長(zhǎng)因子、胰島素樣生長(zhǎng)因子、神經(jīng)生長(zhǎng)因子、集落刺激因子、激素、酶、病毒抗原以及各種重組蛋白等。領(lǐng)先的生產(chǎn)工藝和規(guī)模使其可以提供毫克到克級(jí)蛋白，價(jià)格優(yōu)于同類公司。絕大部分產(chǎn)品是天然成熟型蛋白，而不含有標(biāo)簽蛋白。考慮到大部分研究者希望能更靈活地配制蛋白溶液，ProSpec-Tany絕大部分產(chǎn)品沒有添加保護(hù)劑或鹽，這就對(duì)工藝提出了更高的要求。同時(shí)，ProSpec-Tany絕大部分產(chǎn)品為凍干粉，因此易于運(yùn)輸和保存。
