Specificity / Sensitivity

MAML1 (D3K7B) Rabbit mAb recognizes endogenous levels of total MAML1 protein. This antibody does not detect MAML2 or MAML3.

MAML1 (D3K7B)Rabbit mAb可以识别内源性的总MAML1蛋白。抗体不识别到MAML2或MAML3.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Asp269 of human MAML1 protein.

此单克隆抗体由合成肽段免疫动物产生,该肽段与人MAML1的Asp269邻近氨基酸残基序列一致。

Western Blotting

Western Blotting

Western blot analysis of extracts from various cell lines using MAML1 (D3K7B) Rabbit mAb.

使用MAML1 (D3K7B)Rabbit mAb对多种细胞系提取物进行western blot分析。

IP

IP

Immunoprecipitation of MAML1 protein from 293T cell extracts, using Rabbit (DA1E) mAb IgG XP® Isotype Control #3900 (lane 2) or MAML1 (D3K7B) Rabbit mAb (lane 3). Lane 1 is 10% input. Western blot analysis was performed using MAML1 Antibody #4608.

使用Rabbit (DA1E) mAb IgG XP® Isotype Control #3900 (lane 2)或MAML1 (D3K7B)Rabbit mAb兔单抗(lane3)对293T细胞中的MAML1蛋白进行免疫沉淀实验。Lane1是10%上样量。使用MAML1抗体#4608进行western blot分析。

Chromatin IP

Chromatin IP

CUTLL1 cells were cultured in media with γ-secretase inhibitor (1 μM) for 3 days and then washed and cultured in fresh media for 3 h. Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 106 cells and 5 µl of MAML1 (D3K7B) Rabbit mAb or 2 µl of Normal Rabbit IgG #2729 using SimpleChIP® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003. The enriched DNA was quantified by real-time PCR using human DTX1 intron 3 primers, SimpleChIP® Human HES4 Promoter Primers #7273, and SimpleChIP® Human α Satellite Repeat Primers #4486. The amount of immunoprecipitated DNA in each sample is represented as signal relative to the total amount of input chromatin, which is equivalent to one.

CUTLL1细胞在含有γ-分泌酶抑制剂(1 μM)的培养基中培养三天,清洗后在正常培养基中培养3h。使用SimpleChIP® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003,结合5 µl of MAML1 (D3K7B) Rabbit mAb兔单抗或2 µl Normal Rabbit IgG #2729对已交联的4 x 106细胞的染色质样品进行染色质免疫沉淀实验。 使用human DTX1 intron 3 引物 ,SimpleChIP® Human HES4 Promoter 引物#7273, 和SimpleChIP® Human α Satellite Repeat 引物 #4486对富集的DNA样品进行real-time PCR的定量分析。每个样品的免疫沉淀的DNA量是相对于Input染色质的相对定量,Input染色质量设定值为1。

Background

Mastermind-like (MAML) family of proteins are homologs of Drosophila Mastermind. The family is composed of three members in mammals: MAML1, MAML2, and MAML3 (1,2). MAML proteins form complexes with the intracellular domain of Notch (ICN) and the transcription factor CSL (RBP-Jκ) to regulate Notch target gene expression (3-5). MAML1 also interacts with myocyte enhancer factor 2C (MEF2C) to regulate myogenesis (6). MAML2 is frequently found to be fused with Mucoepidermoid carcinoma translocated gene 1 (MECT1, also know as WAMTP1 or TORC1) in patients with mucoepidermoid carcinomas and Warthin's tumors (7).

Mastermind-like (MAML)家族蛋白是果蝇Mastermind的同源物。该家族在哺乳动物中有3个成员:MAML1,MAML2,和MAML3 (1,2).MAML蛋白与Notch(ICN)的细胞内结构域和转录因子CSL (RBP-Jκ)结合形成复合物调控Notch靶基因表达(3-5)。MAML1可以与肌肉细胞增强因子2C(MEF2C)结合调控肌细胞生成(6)。MAML2经常发现在粘表皮样癌病人和乳头状淋巴性腺囊瘤体内,与粘表皮样癌转位基因1(MECT1,也被称为WAMTP1或TORC1)融合(7)。
