BeyoIHC™系列抗体是经过测试适用于免疫组织化学(Immunohistochemistry, IHC)的高品质抗体,也称病理抗体,很大一部分为重组兔单克隆抗体(Recombinant Rabbit Monoclonal Antibody),通过先进的兔单克隆抗体技术平台研发并生产,无需获取动物的脾脏,仅需分离抗原特异性B细胞并通过基因工程方法克隆抗体基因,然后在哺乳动物细胞中重组表达并最终纯化获得[1-2]。
BeyoIHC™抗体灵敏度更高,背景更低,染色更清晰,定位更精准。BeyoIHC™系列抗体通过反复的筛选和测试,确保灵敏度高、背景低、染色效果好[3]。
BeyoIHC™抗体特异性更强,染色结果更为准确。BeyoIHC™系列抗体大部分都是精心筛选的高效价单克隆抗体,是由单个B细胞淋巴瘤表达,只针对一个抗原表位发生特定的免疫反应,应用于免疫组化时特异性更强,染色结果更为准确[3]。
BeyoIHC™抗体一致性更好,批次间差异更小,结果重复性更好。BeyoIHC™系列抗体很大一部分是重组抗体,具有确定的抗体序列,使用不含任何动物源性物质培养液的哺乳细胞表达体系,生产的可重复性、一致性高,批次间差异小,可避免杂交瘤细胞制备过程中的基因丢失、基因突变和细胞株漂移等问题,所制备的重组抗体的重复性更好[3]。
BeyoIHC™系列抗体主要用于福尔马林固定石蜡包埋(Formalin fixed paraffin embedded, FFPE)样品的免疫组织化学染色(Immunohistochemistry-paraffin or Immunohistochemistry paraffin-embedded, IHC-P)。对于冰冻切片免疫组织化学(Immunohistochemistry frozen sections, IHC-Fr)、细胞免疫荧光(Immunofluorescence, IF)或免疫细胞化学(Immunocytochemistry, ICC)未经测试(Not determined)。同时,BeyoIHC™系列抗体可识别人的相应蛋白,对于小鼠等其它种属很大一部分未经测试。对于未经测试的应用及种属样品,理论上有可能是可以检测的,但须用户自行测试。
BeyoIHC™系列抗体配套提供了免疫染色一抗稀释液,可以用于IHC检测或其它适当用途时的一抗稀释。为进一步提高信噪比,推荐使用QuickBlock™免疫染色一抗稀释液(P0262)、SignalUp™免疫染色一抗稀释液(P0277)用于IHC检测。

Background | Anaplastic lymphoma kinase (ALK) is a tyrosine kinase receptor for pleiotrophin (PTN), a growth factor involved in embryonic brain development. In ALK-expressing cells, PTN induces phosphorylation of both ALK and the downstream effectors IRS-1, Shc, PLCγ, and PI3 kinase. ALK was originally discovered as a nucleophosmin (NPM)-ALK fusion protein produced by a translocation. Investigators have found that the NPM-ALK fusion protein is a constitutively active, oncogenic tyrosine kinase associated with anaplastic lymphoma. Research literature suggests that activation of PLCγ by NPM-ALK may be a crucial step for its mitogenic activity and involved in the pathogenesis of anaplastic lymphomas. A distinct ALK oncogenic fusion protein involving ALK and echinoderm microtubule-associated protein like 4 (EML4) has been described in the research literature from a non-small cell lung cancer (NSCLC) cell line, with corresponding fusion transcripts present in some cases of lung adenocarcinoma. The short, amino-terminal region of the microtubule-associated protein EML4 is fused to the kinase domain of ALK. Investigators have identified ALK translocations with other fusion partners, such as TRK-fused gene (TFG) and KIF5B, which have also been associated with NSCLC. In particular, the EML4-ALK fusion protein has been found in 3-7% of NSCLC samples. |

-20℃保存,一年有效。免疫染色一抗稀释液也可以4℃保存,长期不使用推荐-20℃保存,但冻融可能会导致出现轻微的浑浊和少量不溶物。
注意事项:如果本抗体用于免疫组化(IHC)等实验,请注意回收使用过的稀释抗体。回收的抗体通常可以重复使用1-5次。稀释后的抗体,包括已经使用过的稀释抗体,请4℃保存。
回收后重复使用的抗体,使用方法同新鲜稀释的抗体。如果在重复使用过程中发现抗体出现轻微混浊现象,可以10,000×g离心1-3分钟,取上清用于后续检测。如果回收的抗体出现明显的絮状物或长霉长菌等情况,则可以考虑废弃该抗体。
提供的免疫染色一抗稀释液也可以用于Western blot (WB)等适当用途。如果希望获得最佳的检测效果,推荐使用Western一抗稀释液(P0023)。
抗原修复过程中应防止缓冲液过度蒸发,切勿干片。
