背景资料
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.

溶解建议
提供的人网膜素（Omentin）产品为过滤灭菌的白色冻干粉末；该冻干粉末中每毫克人网膜素（Omentin）是从5mM 磷酸钠缓冲液（pH 7.5）和0.5%甘露醇中冻干产生的.我们建议加无菌的18MΩ-cm水以配制工作储存液到不低于100ug/ml，后继实验过程中可根据实验要求进一步稀释.
保存建议
人网膜素（Omentin）在室温可保存3周，或置于-18℃冻存用于长期保存.重新溶解后可以在4℃冷藏保存至少2-7天；如果想延长保存时间，建议分装（加载体蛋白如0.1% HSA或 BSA）后置于-18℃冻存.请避免反复冻融.
其他
ProSpec 是一家全球著名细胞因子蛋白生产和研发的公司，具有20多年的生产经验，专注于蛋白（重组及合成）生产研发。我们的核心产品包括：干扰素、白介素、骨蛋白、肿瘤坏死因子、成纤维生长因子、瘦素、干细胞因子、催乳素、表皮生长因子、胰岛素样生长因子、神经生长因子、集落刺激因子、激素、酶、病毒抗原以及各种重组蛋白等。 生产工艺和规模使其可以提供毫克到克级蛋白，价格优于同类公司。绝大部分产品是天然成熟型蛋白，而不含有标签蛋白。考虑到大部分研究者希望能更灵活地配制蛋白溶液，ProSpec-Tany绝大部分产品没有添加保护剂或盐，这就对工艺提出了更高的要求。同时，ProSpec-Tany绝大部分产品为冻干粉，因此易于运输和保存。
