SEMA3A抗体(A-12)是一种IgG2b κ小鼠单克隆SEMA3A抗体(也被称为信号素-3A抗体或SEMAD抗体),可通过WB、IP、IF、IHC(P)和ELISA检测小鼠、大鼠和人源的SEMA3A蛋白。SEMA3A抗体(A-12)既有非偶联形式的抗SEMA3A抗体,也有多种偶联形式的抗SEMA3A抗体,包括琼脂糖、HRP、PE、FITC和多种Alexa Fluor®偶联物。信号素(SEMAs)由一系列从昆虫到人类都保守存在的细胞表面和分泌蛋白组成。该家族蛋白的成员大约由750个氨基酸组成(包括信号序列),其定义为一个保守的细胞外"信号素"结构域,大约由500个氨基酸组成,包含14-16个半胱氨酸,许多保守序列块,且没有明显的重复。已知分泌型和细胞结合型信号素在化学上可以吸引和排斥神经轴突的生长,引导复杂神经网络的发展。除了它们在轴突导向中的作用外,信号素也与癌症的发展有关。许多信号素与受体神经纤毛蛋白和神经纤毛蛋白-2结合,从而与VEGF竞争这种相互作用,最终导致血管生成的抑制。功能型信号素的丧失与VEGF的竞争可能在肿瘤发展中起重要作用。

Instead of old c-17 antibody, this new antibody, as it's written that the molecular weight of sema family is around 80-140kDa. Does it mean this antibody is not specific to sema3a? which protein the 140kDa represent for?

Asked by: luoyuan123
Thank you for your question. The Sema3a protein can also show up at higher molecular weights than the different human and murine isoforms between 80 and 90 kDa. More information can be found in PMID 15485501: “The 125 kDa form detected in hippocampus probably originates in cells bearing the dendritic punctate surface pattern that are observed in subiculum. The 160 kDa and higher mass forms were observed mainly in adult aged hippocampus and may be related to Sema3A bands of similar mass observed [in PMID 9118808] in lectin‐enriched extracts from adult chicken brain” For more information please contact our technical service directly.

Can SEMA (A-12): sc-74554 monoclonal antibody be used in IF or IHC with mouse tissue or cells? Will there be non-specific staining?

Asked by: Cweed
Thank you for your inquiry. The use of mouse monoclonal antibodies with mouse samples is very common and typically poses no problem. To eliminate any potential cross-reactivity of an anti-mouse secondary detection reagent, SEMA (A-12): sc-74554 is available in a variety of direct conjugations, such as HRP, PE, FITC and AlexaFluors.
