- Full Protocol
- Sample preparation:
- Fixation and TMA preparation according to PMID: 22688270.
- Cut 4µm TMA sections using a waterfall microtome (ThermoFisher Scientific, HM355S).
- Dry sections ON at RT and then back them for 12-24h at 50°C.
- Deparaffinization and rehydration in xylene and graded alcohol series:
- xylene twice for 3min.
- 100% ethanol for 1min.
- 95% ethanol for 1min.
- 0.3% H2O2 in 95% ethanol for 5min to block endogenous peroxidase.
- 70% ethanol for 1min.
- 50% ethanol for 1min.
- distilled H2O for 2min.
- Antigen Retrieval by Heat Induced Epitope Retrieval (HIER):
- Boil the sections in Lab Vision Citrate buffer pH6.0 (ThermoFisher Scientific, TA-250-PM1X) for 4min at 125°C in a decloaking chamber (Biocare Medical).
- Allow slides to cool down to 90°C in the decloaking chamber.
- Immunostaining in a Lab Vision Autostainer 480 (ThermorFisher Scientific) at RT with 300µl of reagents for each step:
- Rinse sections in Lab Vision wash buffer with extra tween added to a final concentration of 0.2% (ThermoFisher Scientific, TA-999-TT and TA-125-TW) wash buffer.
- Block sections with Lab Vision Ultra V-Block (ThermoFisher Scientific, TA-125-UB) for 5min.
- Rinse sections 2x in wash buffer.
- Incubate sections with primary rabbit anti-IRS1 antibody (antibodies-online, ABIN3042564) diluted 1:1100 for 30min.
- Rinse sections 3x in wash buffer.
- Incubate sections with labeled HRP polymer (ThermoFisher Scientific, TL-125-PH) for 30min.
- Rinse sections 2x in wash buffer.
- Develop in DAB Quanto solution (ThermoFisher Scientific, TL-125-QHDX) for 5min.
- Rinse sections in distilled H2O.
- Washing, counterstaining, and coverslipping in Autostainer XL (Leica Biosystems, ST5010) at RT:
- Counterstaining in Mayer’s hematoxylin plus (HistoLab, 01820) for 7.5min.
- Rinse sections in tap water for 5min.
- Rinse sections in lithium carbonate water diluted 1:5 for 5min.
- Dehydration in graded ethanol series and Neo-Clear (Merck Millipore, 109843) according to the manufacturer recommendations.
- Automated mounting (Leica Biosystems, CV5030) of coverslip with Pertex (Histolab, 00871).
- Microscopy:
- Image acquisition on a Leica Aperio AT2 and Aperio Scanscope AT at 20x magnification.
- Experimental Notes
- ABIN3042564 shows nice IRS1 staining in endothelial cells in most tissues as is supported by both literature and RNA-seq data. At lower dilutions the antibody does also show some cytoplasmic staining in the tested tissues.

Synonyms: Insulin receptor substrate 1,IRS-1,Irs1,Irs-1,
Tissue Specificity: Expressed in osteoblasts, but not in osteoclasts. .
Background: Insulin receptor substrate 1 (IRS-1) is a signalling adapter protein that in humans is encoded by the IRS-1 gene. It is mapped to 2q36.3. This gene exhibited no intrinsic enzyme activity, and it can serve as a docking protein involved in binding and activating other signal transduction molecules after being phosphorylated on tyrosine by insulin receptor kinase. IRS1 plays a key role in transmitting signals from the insulin and insulin-like growth factor-1 (IGF-1) receptors to intracellular pathways PI3K/Akt and Erk MAP kinase pathways. IRS1 also plays important biological function for both metabolic and mitogenic (growth promoting) pathways. In addition to those, IRS1 is a key regulator of PI3K within malignant cells.
Sequence Similarities: Contains 1 IRS-type PTB domain.
