WB
Western blot analysis of Phospho-ELK1 (S383) on different lysates with Rabbit anti-Phospho-ELK1 (S383) antibody at 1/5000 dilution.
Lane 1: RAW264.7 cell lysate,
Lane 2: RAW264.7 treated with 10μg/mL LPS for 8 hours cell lysate,
Lane 3: RAW264.7 treated with 10μg/mL LPS for 8 hours cell lysate, then the membrane treated with λpp for 1 hour,
Lysates/proteins at 20 µg/Lane.
Exposure time: 59 seconds;
4-20% SDS-PAGE gel.
Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody at 1/5000 dilution was used in primary antibody dilution at 4℃ overnight. Goat Anti-Rabbit IgG - HRP Secondary Antibody at 1/50000 dilution was used for 1 hour at room temperature.
IHC
Immunohistochemical analysis of paraffin-embedded human lung tissue untreated / treated with λpp with Rabbit anti-Phospho-ELK1 (S383) antibody at 1/1000 dilution.
The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0) for 20 minutes. The tissues were blocked in 1% BSA for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody at 1/1000 dilution for 1 hour at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.
IP
Phospho-ELK1 (S383) was immunoprecipitated from 0.2 mg RAW264.7 treated with 0.1μg/mL LPS for 6 hours cell lysate with Rabbit anti-Phospho-ELK1 (S383) antibody at 2 µg/10 µl beads. Western blot was performed from the immunoprecipitate using Rabbit anti-Phospho-ELK1 (S383) antibody at 1/25000 dilution. HRP Conjugated Anti-Rabbit IgG for IP Nano-secondary antibody at 1/5,000 dilution was used for 1 hour at room temperature.
Lane 1: RAW264.7 treated with 0.1μg/mL LPS for 6 hours cell lysate (input),
Lane 2: Rabbit anti-Phospho-ELK1 (S383) antibody IP in RAW264.7 treated with 0.1μg/mL LPS for 6 hours cell lysate,
Lane 3: Rabbit IgG instead of Rabbit anti-Phospho-ELK1 (S383) antibody in RAW264.7 treated with 0.1μg/mL LPS for 6 hours cell lysate,
Blocking/Dilution buffer: 5% NFDM/TBST,
Exposure time: 1 minute 2 seconds.
