SIRP-α抗体(SE7C2)是一种小鼠单克隆IgG1 kappa轻链抗体,可通过蛋白质印迹(WB)、免疫沉淀(IP)和流式细胞术(FCM)检测人源SIRP-α蛋白。SIRP-α (SE7C2) 抗体有非结合型和多种结合型,包括琼脂糖、辣根过氧化物酶 (HRP)、藻红蛋白 (PE)、异硫氰酸荧光素 (FITC) 和多种 Alexa Fluor® 结合物。SIRP-α,也称为SIRP-α1、SIRP-α2或SIRP-α3,是一种跨膜糖蛋白,在调节免疫反应中起着至关重要的作用。SIRP-α包含一个具有三个免疫球蛋白样结构的细胞外结构域和一个具有四个潜在酪氨酸磷酸化位点的细胞质区域。SIRP-α主要位于免疫细胞表面,与CD47相互作用,后者是一种"别吃我"信号,可抑制巨噬细胞的吞噬作用。这种相互作用对于维持免疫平衡和预防自身免疫至关重要,因为SIRP-α有助于调节免疫激活和抑制之间的平衡。此外,SIRP-α已被证明可负调控细胞对生长因子和癌基因的反应,从而影响细胞的存活和运动。SIRP-α能够调节这些途径,这凸显了它在正常免疫功能和包括癌症在内的各种疾病发病机理中的重要性。

Is this anti-SIRP alpha antibody cross-react with SIRP beta?. Specifically, I want detect the expression of SIRPa by flow cytometry but I have a concern of this point. Thanks.

Asked by: Pasut Sasithong
Thank you for your question . SIRP-α (SE7C2) antibody does cross react with SIRP beta. It does not cross react with SIRP a2.

Bonjour, Pourriez-vous me dire si cet anticorps est capable de lier les deux isoformes de SIRPa (SIRPa1 et SIRPa2) ou s'il est spécifique de l'un ou de l'autre? Merci.

Asked by: Magali
Merci pour votre requête. Cet anticorps ne réagit pas en Western Blot avec l'isoforme SIRPa2 mais est spécifique de l'isoforme SIRPa1. Thank you for your inquiry. This antibody does not react in Western Blot with isoform SIRPa2 but is specific for isoform SIRPa1.

Bonjour, J'ai besoin de connaître la séquence du domaine/peptide contre lequel a été générée l'anticorps anti-SIRPa SE7C2. Pourriez-vous m'envoyer cette séquence s'il vous plaît ?

Asked by: Vanessa
Merci pour votre question. L'anticorps a été généré contre une protéine recombinante contenant le domaine extracellulaire de SIRPα1 d'origine humaine. http://www.uniprot.org/uniprot/P78324 Thank you for your question. The antibody was generated against a recombinant protein containing the entire extracellular domain of human SIRPα1. http://www.uniprot.org/uniprot/P78324
