Species cross-reactivity is determined by western blot.

Applications Key: W=Western Blotting, IP=Immunoprecipitation, F=Flow Cytometry, IF-IC=Immunofluorescence (Immunocytochemistry),

Specificity / Sensitivity

Phospho-AML1 (Ser249) Antibody detects endogenous levels of AML1 protein only when phosphorylated on Ser249.

Phospho-AML1 (Ser249)抗体能够检测内源性Ser249位点磷酸化的AML1蛋白水平。

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to amino acids around Ser249 of human AML1. Antibodies are purified by protein A and peptide affinity chromatography.

此多克隆抗体是通过合成人源对应的AML1 Ser249位点周围的肽段来免疫动物而获得。抗体是通过protein A和多肽亲和层析纯化。

AML1 (also known as Runx1, CBFA2, and PEBP2αB) is a member of the core binding factor (CBF) family of transcription factors (1,2). It is required for normal development of all hematopoietic lineages (3-5). AML1 forms a heterodimeric DNA binding complex with its partner protein CBFβ and regulates the expression of cellular genes by binding to promoter and enhancer elements. AML1 is commonly translocated in hematopoietic cancers: chromosomal translocations include t(8;21) AML1-ETO, t(12;21) TEL-AML and t(8;21) AML-M2 (6). Phosphorylation of AML1 on several potential serine and threonine sites, including Ser249, is thought to occur in an Erk-dependent manner (7,8).

AML1 (也叫做Runx1, CBFA2 或 PEBP2αB)是转录因子核心结合因子(CBF)家族中的一员(1,2)。它对造血细胞系的正常发育是不可缺少的(3-5)。AML1与其伴侣蛋白CBFβ形成异二聚体DNA结合复合体,并通过结合启动子和增强子原件而调控细胞基因的表达。AML1 在造血相关癌症中通常发生染色体易位,易位的位置包括t(8;21) AML1-ETO、t(12;21) TEL-AML 和 t(8;21) AML-M2 (6)。磷酸化AML1的几个潜在丝氨酸和苏氨酸位点包括Ser249, 被认为是通过Erk依赖的方式而发生修饰 (7,8)。
