背景資料

Omentin is a recently recognized gene highly localized to the mental tissue （visceral adipose tissue）. Omentin is present in the stromal vascular cells in the adipose tissue rather than in the adipocytes. Omentin is predominantly expressed in the visceral adipose tissue than the subcutaneous tissue，with the omentin mRNA being 150 times higher in the visceral adipose tissue. Omentin has also been detected in human blood using western blot analysis，and seems to increase insulin-stimulated glucose uptake in 3T3-L1 adipocytes in mice. Omentin seems to increase Akt phosphorylation irrespective of insulin presence. Its role in glucose metabolism and obesity remains to be described； an insulin-sensitizing action is possible.Differences in Omentin expression has been noted in adipose tissue from normals and patients with inflammatory bowel disease although its significance is unknown.

溶解建議

提供的人網(wǎng)膜素（Omentin）產(chǎn)品為過(guò)濾滅菌的白色凍干粉末；該凍干粉末中每毫克人網(wǎng)膜素（Omentin）是從5mM 磷酸鈉緩沖液（pH 7.5）和0.5%甘露醇中凍干產(chǎn)生的.我們建議加無(wú)菌的18MΩ-cm水以配制工作儲(chǔ)存液到不低于100ug/ml，后繼實(shí)驗(yàn)過(guò)程中可根據(jù)實(shí)驗(yàn)要求進(jìn)一步稀釋.

保存建議

人網(wǎng)膜素（Omentin）在室溫可保存3周，或置于-18℃凍存用于長(zhǎng)期保存.重新溶解后可以在4℃冷藏保存至少2-7天；如果想延長(zhǎng)保存時(shí)間，建議分裝（加載體蛋白如0.1% HSA或 BSA）后置于-18℃凍存.請(qǐng)避免反復(fù)凍融.
