• 

  WB analysis using 80218-1-RR

  Non-treated and Calyculin A treated PC-3 cells were subjected to SDS PAGE followed by western blot with 80218-1-RR (Phospho-ULK1 (Ser556) antibody) at dilution of 1:5000 incubated at room temperature for 1.5 hours. The membrane was tripped and re-blotted with mouse anti-mTOR antibody 66888-1-Ig as loading control.

  WB analysis using 80218-1-RR

  Non-treated and Calyculin A treated HeLa cells were subjected to SDS PAGE followed by western blot with 80218-1-RR (Phospho-ULK1 (Ser556) antibody) at dilution of 1:5000 incubated at room temperature for 1.5 hours. The membrane was tripped and re-blotted with mouse anti-mTOR antibody 66888-1-Ig as loading control.

  FC experiment of PC-3 using 80218-1-RR

  1X10^6 PC-3 cells untreated (dashed lines) or treated with Calyculin A (red) were intracellularly stained with 0.5 ug Anti-Human Phospho-ULK1 (Ser556) (80218-1-RR, Clone:2F5) and CoraLite®488-Conjugated Goat Anti-Rabbit IgG(H+L) at dilution 1:1000, or 0.5 ug Control Antibody (blue). Cells were fixed with 4% PFA and permeabilized with 90% MeOH.

Tested Applications

• Positive WB detected in: PC-3 cells, HeLa cells, Calyculin A treated HeLa cells, Calyculin A treated PC-3 cells
• Positive FC (Intra) detected in: Calyculin A treated PC-3 cells

This antibody is equivalent to Ser555 in mice.

Recommended dilution

• Western Blot (WB): WB : 1:2000-1:10000
• Flow Cytometry (FC) (INTRA): FC (INTRA) : 0.50 ug per 10^6 cells in a 100 µl suspension

It is recommended that this reagent should be titrated in each testing system to obtain optimal results.

Background Information

Unc-51-like-kinase 1 (ULK1) is a target of both the mechanistic target of rapamycin (mTOR) and AMP activated protein kinase (AMPK), whose role is to facilitate the initiation of autophagy in response to starvation. ULK1 is phosphorylated on serine 638 and 758 sites by mTOR in nutrient-rich conditions, inhibiting ULK1 activation by disrupting its binding to AMPK. Upon glucose starvation, dissociation of mTOR from ULK1 and phosphorylation by AMPK leads to the activation of ULK1 activity. The S556 site of ULK1 is one of the major AMPK-dependent phosphorylation sites. (PMID: 30517873, PMID: 21258367)
