Validierungsbilder

Flow cytometric analysis of cells stained with ABIN740445 and an AF680-conjugated secondary antibody (A) or the secondary antibody only (B). The top row illustrates the gating for life cells. The second and third row show dots blots and histograms respectively of the positively stained cell populations.

Protokoll

Primärantikörper: ABIN740445

Sekundärantikörper: donkey anti-rabbit Alexa Fluor 680 conjugated antibody (ThermoFisher Scientific, A10043, lot 1812322)

Full Protocol:

• Grow rat adipose-derived mesenchymal stem cells in DMEM high glucose, GLUTAMAX, pyruvate supplemented (Gibco, 31966021, lot 1774921) supplemented with 10% fetal bovine serum (Gibco, 16000044, lot 1774921) 1% penicillin/streptomycin (Gibco, 15140122, lot 1759446), at 37°C and 5% CO₂ in ml on a flask to 95% confluency.
• Wash cells with PBS buffer.
• Detach cells from the flask with trypsin-versene solution (Lonza, H3BE17-161E, lot RB35937) for 3min at 37°C and 5% CO₂.
• Centrifuge cells for at 400xg for 5min at RT, aspirate the supernatant.
• Resuspend cells in 1mL of 1% BSA in PBS per 2x10⁶ cells and incubate 20min at RT.
• Incubate cells with primary rabbit anti-CD137 antibody (antibodies-online, ABIN740445, lot AG05152084) diluted 1:35 in 1% BSA in PBS buffer for 20min on ice. Include a negative control without primary antibody.
• Wash cells 1x with PBS buffer and centrifuge them for 400xg for 5min at RT.
• Resuspend cells in 175μl 1% BSA in PBS buffer.
• Incubate cells with secondary donkey anti-rabbit Alexa Fluor 680 conjugated antibody (ThermoFisher Scientific, A10043, lot 1812322) diluted 1:200 in buffer for 15min in ice.
• Wash cells 2xwith PBS buffer and centrifuge them for 400xg for 5min at RT.
• Resuspend the pellet in 500μl PBS buffer.
• Data acquisition in a BD FACSCanto II flow cytometer, equipped with two laser lines of 488nm and 633nm and two scattered light detectors (FSC and SSC). Detect fluorescence in PMTs with filters suitable for the fluorescence of the fluorophore AF680 (735LP and 780/60BP). Threshold is established in FSC. The data is saved in files in FCS format and analyzed offline with the FACSDiva software (BD).

Anmerkungen:

ABIN740445 reveals a specific fluorescence signal in rat adipose-derived mesenchymal stem cells. This is the first time that flow cytometry is performed in this type of cells using this antibody. No signal was registered in the negative control cells.
