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.
神经调节素1(NRG1)重组蛋白Ready-to-use: No need to heat, dilute or add reducing agents before use.

文献和实验从罕见病到“不限癌种”,NRG1靶点凭什么一年内连斩三大适应症?
2026年5月,FDA批准Partner Therapeutics的Bizengri(zenocutuzumab)扩展适应症,用于治疗携带NRG1基因融合的晚期胆管癌患者,成为全球首--款专门针对NRG1阳性胆管癌的靶向疗法。此前,Bizengri已获批用于NRG1融合阳性的胰腺癌和非小细胞肺癌,此次拓展进一步验证了该靶点作为“不限癌种”罕见驱动基因的临床价值。NRG1——这一曾在神经系统发育、心脏功能维持中备受关注的神经调节蛋白,如今在肿瘤精准治疗领域迎来高光时刻
神经调节蛋白基因之后,会重新获得保护层(protective layer)。 (Fig: Schematic Summary of Abnormalities in Nerves with Altered NRG1 Type III Levels) 参看英文原文: Neuregulin-1 Type III Determines the Ensheathment Fate of Axons Volume 47, Issue
采用6xHistidine-tag进行第一步的收集。由于6xHistidine-tag对Ni-NTA matrix具有极高的亲和能力,通过分批纯化,重组蛋白可以高效收集。作为阳性负对照, 生物 素与Strep-tag纯化系统不兼容,其通常存在于培养基中,经过6xHistidine-tag的收集,生物素可以除去。如果由必要,可以采用Strep-tag作为第二步纯化以获得更高纯度的蛋白。
