アプリケーション

Our Abpromise guarantee covers the use of ab70784 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

アプリケーション Abreviews 特記事項
ICC/IF Use a concentration of 1 µg/ml.
IHC-P Use a concentration of 1 µg/ml. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
WB Use a concentration of 0.5 - 4 µg/ml. Detects a band of approximately 30, 50 kDa (predicted molecular weight: 30, 50 kDa).Can be blocked with Insig1 peptide (ab126817).

ターゲット情報

  • 機能Mediates feedback control of cholesterol synthesis by controlling SCAP and HMGCR. Functions by blocking the processing of sterol regulatory element-binding proteins (SREBPs). Capable of retaining the SCAP-SREBF2 complex in the ER thus preventing it from escorting SREBPs to the Golgi. Seems to regulate the ubiquitin-mediated proteasomal degradation of HMGCR. May play a role in growth and differentiation of tissues involved in metabolic control. May play a regulatory role during G0/G1 transition of cell growth.
  • 組織特異性Expressed in all tissues tested with highest expression in the liver.
  • 配列類似性Belongs to the INSIG family.
  • 翻訳後修飾Ubiquitinated. Subsequent to sterol deprivation, the SCAP-SREBF2 complex becomes dissociated from INSIG1, is then ubiquitinated and degraded in proteasomes. Although ubiquitination is required for rapid INSIG1 degradation, it is not required for release of the SCAP-SREBP complex. Ubiquitinated by RNF139.

Anti-Insig1 antibody 画像

  • Anti-Insig1 antibody (ab70784) at 0.5 µg/ml + Jurkat cell lysate

    Predicted band size : 30, 50 kDa
    Observed band size : 30,50 kDa
  • ICC/IF image of ab70784 stained HeLa cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab70784, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

  • IHC image of ab70784 staining in Human normal liver 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 ab70784, 10µg/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.

Thank you for your inquiry.

I can confirm that Insig1 (Insulin-induced gene 1 protein) is expressed in many tissues (http://www.ncbi.nlm.nih.gov/pubmed/12202038).

Jurkat cells endogenously express Insig1 which makes them a good (and...
