“应用说明”部分 下显示的仅为推荐的起始稀释度;实际最佳的稀释度/浓度应由使用者检定。

应用 Ab评论 说明
WB (1)
1/1000. Detects a band of approximately 11 kDa (predicted molecular weight: 11.5 kDa).
IHC-P
Use at an assay dependent concentration.
ChIP (1)
Use at an assay dependent concentration.

See Abreview submitted on 15 December 2009.

ICC/IF
1/250 - 1/500.

Although this antibody gives a specific signal in Immunofluoresence, we have had suggestions that strong background signals are seen. See review by Robert Hock and IF picture below.

靶标

  • 功能

    HMG-I/Y bind preferentially to the minor groove of A+T rich regions in double stranded DNA. It is suggested that these proteins could function in nucleosome phasing and in the 3'-end processing of mRNA transcripts. They are also involved in the transcription regulation of genes containing, or in close proximity to A+T-rich regions.
  • 疾病相关

    Note=A chromosomal aberration involving HMGA1 is found in pulmonary chondroid hamartoma. Translocation t(6;14)(p21;q23-24) with RAD51L1.
  • 序列相似性

    Belongs to the HMGA family.
    Contains 3 A.T hook DNA-binding domains.
  • 翻译后修饰

    Constitutively phosphorylated on two or three sites. Phosphorylated upon DNA damage, probably by ATM or ATR. Hyperphosphorylated at early stages of apoptosis, followed by dephosphorylation and methylation, which coincides with chromatin condensation. Isoform HMG-Y can be phosphorylated by HIPK2.
    HMG-Y is not methylated.
    Methylation at Arg-58 is mutually exclusive with methylation at Arg-60.
  • 细胞定位

    Nucleus. Chromosome.

    Western blot using ab4078.

    Whole cell lysate from HepG2 cells transfected with plasmids coding for hHMGA1a-, hHMGA1b-, hHMGA2- or NLS- (nuclear localisation signal) GFP fusion proteins.

    ab4078 was diluted 1/1000 in 5% milk/TBS and incubated for 1 hr at room temperature. Secondary HRP anti-rabbit antibody was diluted 1/10000 in 5% milk/TBS and incubated for 1 hr at room temperature.

    Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-HMGA1a / HMGA1b antibody (ab4078)
    IHC image of ab4078 staining in human placenta formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab4078, 1µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

Asked on Sep 14 2011

Answer

I am sorry this product did not perform as stated on the datasheet and for the inconvenience this has caused. As requested, I have issued a free of charge replacement (from a different lot) with the order number 949551. To check the status of the order please contact our Customer Service team and reference this number. Please note that this free of charge replacement vial is also covered by our Abpromise guarantee. Should you still be experiencing difficulties, or if you have any further questions, please do not hesitate to let us know. I wish you the best of luck with your research.
