Western blot analysis of Phospho-STING (S366) on different lysates with Rabbit anti-Phospho-STING (S366) antibody at 1/2,000 dilution.
Lane 1: THP-1 treated with 80nM TPA for 16 hours cell lysate,
Lane 2: THP-1 treated with 80nM TPA for 16 hours then transfected with 5μg/mL Poly (dA:dT) for 3 hours cell lysate,
Lane 3: THP-1 treated with 80nM TPA for 16 hours then transfected with 5μg/mL Poly (dA:dT) for 3 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 1/2,000 dilution was used in 5% NFDM/TBST at 4℃ overnight. Goat Anti-Rabbit IgG - HRP Secondary Antibody at 1/50,000 dilution was used for 1 hour at room temperature.

Phospho-STING (S366) was immunoprecipitated from 0.2 mg THP-1 treated with 80nM TPA for 16 hours then transfected with 5μg/mL Poly (dA:dT) for 3 hours cell lysate with Rabbit anti-Phospho-STING (S366) antibody at 2 µg/10 µl beads. Western blot was performed from the immunoprecipitate using Rabbit anti-Phospho-STING (S366) antibody at 1/1,000 dilution. Mouse Anti-Rabbit IgG kappa light chain secondary antibody at 1/5,000 dilution was used for 1 hour at room temperature.
