Numéro du lot: 110517

Application validée: Western Blotting

Contrôle positif: primary mouse microglia

Contrôle négative: siRNA knock-down of CREB1 in primary mouse microglia

Conclusion: Passed. ABIN969061 specifically recognizes Creb1 in primary mouse microglia lysates.

Validation Images

Primary mouse microglia were transfected with Creb1 siRNA and Creb1 was revealed using ABIN969061 as described in the protocol section (lanes 1, 2, and 3). Lysates from cells transfected with scrambled siRNA (lane 4) and untransfected cells (lane 5) served as negative controls.

Protocole

Anticorps primaire: ABIN969061

Anticorps secondaire: anti-mouse HRP-conjugated antibody (DakoCytomation, P0447, lot 00058737)

Full Protocol:

• Primary mouse microglia are grown in DMEM (Invitrogen), supplemented with 10% foetal bovine serum (Gibco), 10% horse serum and penicillin and streptomycin (Gibco), at 37°C and 5% CO2 in a 12-well dish.
• Transfect cells with 0.05nmol mouse Creb1 Silencer Select siRNA (ThermoFisher Scientific, ASO1093M, ASO10982 and ASO109CG, lot AMO04BXD) using Lipofectamine 3000 (Invitrogen) following the manufacturer’s instructions.
• Lyse cells in 25µl per well cold lysis buffer (10mM Tris-HCl pH 8.0, 150mM NaCl, 1% Nonidet-P40, 1mM EDTA, 10mM NaF, 1mM Na₃VO₄, containing protease inhibitors (Sigma)).
• Determine total protein content of the lysates using Bradford assay (Bio-Rad, 500-0006, lot 111832).
• Denature 5µg of total protein for 5min at 95°C in 5µl Laemmli SDS sample buffer and subsequently separate them on a denaturing, freshly cast 10% SDS-PAGE for 1h at 140V.
• Transfer proteins onto PVDF membrane (Pall Life Sciences, 75696G, lot TO3225) with a semi-dry Western blotting system for 50min at 60mA.
• Block the membrane with TBST (TBS, 0.1% Tween) containing 5% milk ON at 4°C.
• Incubation with primary mouse anti-CREB1 antibody (antibodies-online, ABIN969061, lot 110517) diluted 1:10000 in TBST containing 5% milk for 1h at RT.
• Wash membrane 5x 5min with TBST.
• Incubation with anti-mouse horseradish peroxidase-conjugated secondary antibody (DakoCytomation, P0447, lot 00058737) diluted 1:2000 in TBST containing 5% milk for 1h at RT.
• Wash membrane 5x 5min with TBST and 3x 5min with TBS.
• Reveal protein bands using self-made ECL Western Blotting Detection Reagent with Curix RP2 Plus medical X-ray films (AGFA Health Care, ENKMV, lot 79040074) on an AGFA Health Care Curix60-developer.
• Strip membranes using RestoreTM Western Blot Stripping Buffer (Thermo Scientific, 21059, lot NA 164269) and subsequently incubate with a GAPDH loading control antibody (Sigma, G9545, lot 049K4787) diluted 1:10000 and with anti-rabbit horseradish peroxidase-conjugated secondary antibodies (DakoCytomation, P0448, lot 00055814) diluted 1:2000.
• Wash and reveal the membrane as described above.

Notes: The CREB1 antibody ABIN969061 reveals a protein of the expected molecular weight of murine Creb1 in lysates of primary mouse microglia. The protein band’s intensity decreases upon siRNA knockdown.

Sujet:

Description: This gene encodes a transcription factor that is a member of the leucine zipper family of DNA binding proteins. This protein binds as a homodimer to the cAMP-responsive element, an octameric palindrome. The protein is phosphorylated by several protein kinases, and induces transcription of genes in response to hormonal stimulation of the cAMP pathway. Alternate splicing of this gene results in two transcript variants encoding different isoforms. (provided by RefSeq)
