產(chǎn)品基本介紹：

DESCRIPTION

Betacellulin Bovine Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 80 amino acids and having a molecular mass of 9003 Dalton.
Betacellulin Bovine Recombinant is purified by proprietary chromatographic techniques.

SOURCE

Escherichia Coli.

PHYSICAL APPEARANCE

Sterile Filtered White lyophilized (freeze-dried) powder.

FORMULATION

The Betacellulin Bovine Recombinant was lyophilized after extensive dialysis against 50mM acetic acid.

SOLUBILITY

It is recommended to reconstitute the lyophilized BTC Bovine in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

BIOLOGICAL ACTIVITY

The ED₅₀, calculated by the dose-dependent proliferation of murine BALB\C 3T3 cells (measured by 3H-thymidine uptake) is < 10.0 ng/ml, corresponding to a Specific Activity 100,000 units/mg.

品牌介紹：

ProSpec是一家全球著名細(xì)胞因子蛋白及相關(guān)抗體生產(chǎn)和研發(fā)品牌。ProSpec的生產(chǎn)和研發(fā)工廠位于以色列，專注于蛋白（重組及合成）生產(chǎn)研發(fā)，其細(xì)菌和哺乳動物表達(dá)和蛋白折疊技術(shù)使其能在17年內(nèi)成長為國際的科研級蛋白供應(yīng)商。目前ProSpec可以提供細(xì)胞因子，生長因子，激素，信號蛋白，病毒抗原等近800種重組蛋白和100多種抗體，是世界上提供蛋白品種最多的公司之一，生產(chǎn)工藝和規(guī)模使其可以提供毫克到克級蛋白，價格優(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，這就對工藝提出了更高的要求。同時，ProSpec-Tany絕大部分產(chǎn)品為凍干粉，因此易于運輸和保存。
