    Rabbit polyclonal to IRS2 (phospho S731)
  • 特異性This antibody is specific for human IRS2 phosphorylated at the position of Serine 731. The antibodies were evaluated for specificity with a dot blot assay using synthetically prepared IRS peptides. It only recognizes the phosphorylated serine 731, not other phosphorylated sites or non-phosphorylated IRS 1 or IRS 2.

    Synthetic peptide (YKASSpPAESS), corresponding to amino acids 727-736 of human IRS2 at the phosphorylated site of Serine 731. This synthetic peptide also correlates to amino acids 719-728 of mouse IRS2 at the phosphorylation site of Serine 723 and to amino acids 229-238 of rat IRS2 at the serine phosphorylation site 233.

アプリケーション

Our Abpromise guarantee covers the use of ab3690 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
WB Use a concentration of 0.5 - 2 µg/ml. Detects a band of approximately 200 kDa. in cell lysate derived from mouse serum-treated fibroblasts, which corresponds to the predicted molecular weight of phospho IRS 2. Samples were boiled prior to subject 7.5% SDS-polyacrylamide gelelectrophoresis.
IP Use at an assay dependent concentration. Use at a concentration of 3.0 - 5.0 µg / extract from 107 cells.
ELISA Use a concentration of 0.1 - 1 µg/ml.
IHC-P Use a concentration of 2 µg/ml.

  • IP: 3T3 cell lysate immunoprecipitated with Anti-IRS-2 (pSER731) (ab3690)
  • ab3690 (2µg/ml) staining IRS2 (phospho S731) in human cerebellum using an automated system (DAKO Autostainer Plus). Using this protocol there is strong staining of the cell membrane.
    Sections were rehydrated and antigen retrieved with the Dako 3 in 1 AR buffer EDTA pH 9.0 in a DAKO PT link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 mins. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 min and detected with Dako envision flex amplification kit for 30 minutes. Colorimetric detection was completed with Diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that, for manual staining, optimization of primary antibody concentration and incubation time is recommended. Signal amplification may be required.

Thank you for your reply. I apologize for the confusion, but I figured out what the problem was. The BLAST was picking up a fragment of the protein, where that sequence was within the amino acid range I mentioned. In the full length sequence, you ...

Thank you for your enquiry. I'm not sure I understand your question. On the datasheet, it states that the immunogen peptide sequence "also correlates to amino acids 129-138 of mouse IRS2 at the phosphorylation site of Serine 133 and to amino acids ...
