产品描述：The transforming Growth Factors beta (TGF beta) family of cytokines are ubiquitous, multifunctional, and essential to survival. They play the central roles in growth, development, inflammation, repair, and host immunity. The mammalian TGF beta isoforms (TGF beta 1, beta 2 and beta 3) are secreted as potential precursors and possess a variety of cell surface receptors and produces at least two mediate signal transductions.

别名：transforming growth factor beta 1, Differentiation inhibiting factor, Cartilage-inducing factor, Tgfb-1

蛋白编号：P04202(Mouse), P17246(Rat)

表达系统：Escherichia coli

纯度：>98% as determined by SDS-PAGE.

别名：Interleukin-1 Beta; IL-1 Beta; Il1b

生物活性：Measure by its ability to inhibit the IL-4 dependent proliferation in HT-2 cells. The ED₅₀ for this effect is <0.1 ng/mL.

分子量：The protein has a calculated MW of 13.8 kDa. The protein migrates as 16 kDa under reducing condition (SDS-PAGE analysis).

标签：His Tag (C-term)

产品形式：The protein was lyophilized from a 0.2 µm filtered solution containing 20 mM sodium citrate, 0.2 M NaCl, pH 3.5.

干粉复溶：

Always centrifuge tubes before opening.Do not mix by vortex or pipetting.

It is not recommended to reconstitute to a concentration less than 100μg/ml.

Dissolve the lyophilized protein in distilled water.

Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
