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-MADCAM1 antibody (antibodies-online, ABIN3044076) diluted 1:900 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.

Background: MADCAM1(Mucosal Vascular Addressin Cell Adhesion Molecule 1), also known as MACAM1, is a protein that in humans is encoded by the MADCAM1 gene. By PCR-based analysis of somatic cell hybrids, Leung et al.(1997) mapped the MACAM1 gene to chromosome 19. The protein encoded by this gene is an endothelil cell adhesion molecule that interacts preferentially with the leukocyte beta7 integrin LPAM-1(alpha4 / beta7), L-selectin, and VLA-4(alpha4/beta1) on myeloid cells to direct leukocytes into mucosal and inflamed tissues. It is a member of the immunoglobulin superfamily and is similar to ICAM-1 and VCAM-1.
