Protokoll

Primärantikörper: ABIN6261511

Sekundärantikörper: goat anti-rabbit HRP-conjugated antibody (Invitrogen, G21234)

Full Protocol:

• Grow A549 cells (ATCC, CCL-185) in DMEM medium (Corning, 10-013-CV) supplemented with 10% FBS (Atlanta biologicals, S11150) and Penicillin-Streptomycin (Corning, 30-002-CI), at 37°C and 5% CO₂ to 3x10⁴ cells/cm² in 2ml on a 6 well plate (Costar, 3516).
• Wash cells once with 1x PBS treat with trypsin (Corning, 25-053-CI).
• Take cells up in growth medium.
• Wash cells once with 1x PBS.
• Resuspend approximately 2.05x10⁵cells/well in 50-100µl 1x LDS sample buffer (Life Technologies, B0007). As positive control, take 20µg recombinant ELF1 (Abnova, H00001997-P01) in 1x LDS sample buffer.
• Denature samples for 3min at 95°C and subsequently keep them on ice.
• Separate samples on a Bolt 4-12% Bis-Tris Plus Gel (Invitrogen, NW04122) in an electrophoresis chamber (Mini Gel Tank, Invitrogen, A25977) for 30min at 80V and then for 60min at 120V.
• Transfer proteins onto nitrocellulose membrane (Invitrogen, IB23002) using an iBlot 2 Gel Transfer Device (Invitrogen).
• Block the membrane with TBS containing 0.05% Tween (TBST) containing 5% skim milk for 1h at RT.
• Incubation with primary
• • rabbit anti-ELF1 antibody (antibodies-online, ABIN6261511, 4318850) diluted 1:1000 in TBST containing 0.5% skim milk ON at 4°C.
  • loading control mouse anti-beta actin antibody (Invitrogen, MA5-15739) diluted 1:5000 in TBST containing 0.5% skim milk ON at 4°C.
• Wash membrane 3x for 10min with TBST.
• Incubation with secondary
• • goat anti-rabbit HRP-conjugated antibody (Invitrogen, G21234) diluted 1:10000 in TBST containing 0.5% skim milk for 1h at RT.
  • goat anti-mouse HRP-conjugated antibody (Invitrogen, G21040) diluted 1:10000 in TBST containing 0.5% skim milk for 1h at RT.
• Wash membrane 3x for 10min with TBST.
• Reveal protein bands using SuperSignal West Dura Extended Duration Substrate (ThermoFisher Scientific, 34075) and a ChemiDoc MP Imaging System (Bio-Rad).

Anmerkungen:

• ABIN6261511 reveals a protein with an apparent molecular weight of approximately 62kDa. The expected molecular weight for endogenous human ELF1 is approximately 67kDa. The antibody also reveals a recombinant GST-tagged protein at the expected molecular weight (theoretical MW 93.9kDa).

• Other ELF1-antibody dilutions were tested, but a dilution of 1:2500 was found optimal in terms of minimal background and strength of signal.
