    Full Protocol
    • Isolate monocytes from healthy donor from PBMCsprepared by Ficoll-Hypaque density gradient and enriched by plastic adherence in 3ml volume on a 6 well-platefor 90min at 37°C in RPMI (Gibco, 21875-034, lot 1926384) supplemented with 1.5% of human serum (pooled serum from healthy donors). Cultivate adherent cells for 24h in RPMIsupplemented with 10% human serum and PenStrep (Sigma, P0781, lot 077M4843V), at 37°C and 5% CO2 in 3ml volume on a 6 well-plate to 60-70% confluency.
    • Cultivate 293T cells, AML cells and Ma-Mel86B cells in RPMI (Gibco, 21875-034, lot 1926384) supplemented with FCS (Sigma, F7524, lot BCBS0318V) and PenStrep (Sigma, P0781, lot 077M4843V) at 37°C and 5% CO2 in cell culture bottles or in petri-dishes to 60-70% confluency.
    • Cultivate MRC-5 cells in RPMI supplemented with 20% FCS and 1% PenStrep.
    • Cultivate HUVEC cells in EGM-2 (Lonza) supplemented with 1% PenStrep.
    • Cultivate CAF cells (MEM Eagle 10% FCS, 1% PenStrep, Na-Pyruvate, non essential amino acids, L-Glutamin).
    • Transfect cells with 300ng of the pcDNA3.1-human VTN-cDNA construct using Lipofectamin 2000 (Invitrogen, 11668-019, lot 1641316) following the manufacturer´s instructions.
    • Wash cells with FACS buffer.
    • Centrifuge cells at 500xg for 5min at RT, aspirate the supernatant.
    • Resuspend cells in 2ml ice-cold FACS buffer (PBS, 0.1% BSA, 2mM EDTA).
    • Wash the cells 1x with FACS buffer and centrifuge them for 500xg for 5min at RT.
    • Primary antibody:
      • Prepare three different dilutions (1:20, 1:100 and 1:200) of the mouse anti-human VTN antibody (antibodies-online, ABIN2477109, lot 300615) in FACS buffer. Add 50µl of each antibody dilution directly on the cell pellet and incubate for 30min at 4°C.
      • Resuspend the cell pellet with 100µl of FACS buffer with IgG1 isotype control antibody (Beckmann Coulter, product no IM0571, lot 35). Add 5µl directly on the pellet and incubate for 30min at 4°C.
    • Wash cells 1x with FACS buffer and centrifuge them for 500xg for 5 min at RT.
    • Resuspend the cell pellet with 50µl of FACS buffer with in secondary Goat- anti-mouse FITC antibody (antibodies-online, ABIN4323449, lot 132660) diluted 1:50 in FACS buffer and incubate for 30min at 4°C.
    • Wash cells 1x with FACS buffer and centrifuge them for 500xg for 5min at RT.
    • Resuspend pellet in 200µl 1% Paraformaldehyde solution to fix cells.
    • Data acquisition in a BD FACSCanto II flow cytometer using Blue laser 488nm and filter 530/30.
    Notes
    • Total RNA was isolated from different cell lines and primary cells and transcribed into cDNA. The full-length VTN ORF was amplified by PCR with specific primers and the PCR product was sequence-verified. PCR-positive Ma-Mel-86B cells served as positive control. Freshly isolated monocytes, MUTZ-3 cells, human primary AML cells and 293T cells served as negative controls.

    • ABIN2477109 (1:20 dilution) reveals a specific fluorescence signal in Ma-Mel-86B positive control cells in 60% of the registered events. Although freshly isolated monocytes were negative by PCR, they show 21% cell surface expression of Vitronectin by FACS staining (low surface expression defined by a shift of the total cell population).

    • The percentage of VTN positive cells could not be increased by transient transfection of monocytes with pcDNA3.1-human VTN-cDNA construct. Nevertheless, it seems that the surface expression of Vitronectin in the VTN positive population is higher and more concentrated to a part of cell population. This might indicate that ABIN2477109 specifically bind to VTN expressed on the transfected cells.

    • No signal was registered in different primary cells: MRC-5 (primary fibroblast cells), HUVEC (primary endothelial cells) and CAF (cancer associated fibroblast cells).

    • The antibody titration experiment reveals that the optimal dilution of the antibody for FACS staining was 1:20. Due to the small volume (25µl) of antibody provided, we did not have enough material to test other cells lines/primary cells.
