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
ITGA4（CD49D）信号通路、病理作用与靶向治疗药物研究梳理
整合素alpha 4（ITGA4），又称CD49D，是整合素家族的关键亚基。它通过与β1或β7亚基结合，形成功能性异二聚体α4β1（VLA-4）和α4β7，在免疫细胞的黏附、运输及迁移中扮演核心角色。VLA-4还能介导白细胞在活化内皮细胞上的聚集。鉴于ITGA4在多发性硬化、炎症性肠病等多种自身免疫性疾病的病理过程中发挥关键作用，它已成为治疗干预的重要靶点。 ITGA4的表达分布 ITGA4主要分布于巨核细胞、红细胞、干细胞、NK细胞以及T细胞中。在T细胞亚群中，CD49D主要在CD
