Stability Test: The thermal stability is described by the loss rate of the target protein. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37oC for 48h, and no obvious degradation and precipitation were observed. (Referring from China Biological Products Standard, which was calculated by the Arrhenius equation.) The loss of this protein is less than 5% within the expiration date under appropriate storage condition.
Protein bands: 10kDa, 14kDa, 18kDa, 22kDa, 26kDa, 33kDa, 44kDa and 70kDa.
Double intensity bands: The 26kDa, 18kDa, 10kDa bands are at double intensity to make location and size approximation of proteins of interest quick and easy.
胸腺素β4(Tβ4)重组蛋白Ready-to-use: No need to heat, dilute or add reducing agents before use.

文献和实验A rapid and sensitive assay for quantification of siRNA efficiency and specificity
activity to provide a quantitative readout of relative RNAi efficacy and specificity. We have tested different siRNAs directed against Thymosin β4 (Tβ4 ); determined their effectiveness at silencing Tβ4 and have both excluded off-target silencing of the Tβ4
Nature 子刊：中国团队在扇贝足丝蛋白仿生材料研究领域取得重要研究进展
327 ± 32%(图 1a)，超过了绝大多数天然的生物纤维（图 1b）。通过对足丝纤维部 (图 1c) 微观结构进行观察，足丝纤维由折叠的片层组成，并且富含 β-sheet 结构 (图 1d)。基于多组学技术从足丝纤维部筛选出关键蛋白组分 Sbp5-2（图 1e）, 该蛋白具有显著的序列特点：含有多个重复模块（TRM）并且富含 Cys（图 1f）。体外重组表达该蛋白的重复模块序列成功制备了仿扇贝足丝的重组蛋白纤维（图 1 g-j）。 图 1. 扇贝足丝机械性能与结构以及重组蛋白纤维制备 体外
茨海默病（AD）老年期常见大脑类疾病，他以进行性记忆力减退和认知功能障碍为主要特征的。目前大脑经过哪些活动会引起阿尔茨海默病仍不十分明确，但 Aβ（β-淀粉样蛋白）的产生和聚集一直被认为是重要因素之一。最新研究发现，在脑的「私生活」中，Aβ存在类似于抗菌肽一样的「正面角色」——保护大脑免于病原体的侵袭。 这么一说，小编就更加不明白了「Aβ到底是好还是坏？」 跟着小编一起涨涨知识，看看 Aβ是个什么神通广大的东西，既能保护大脑还能让全世界 3.5 亿人丧失
