Filter:
  • Western Blot (WB) analysis of various lysates using Phospho-STK11/LKB1 (Thr189) Recombinant antibody (80127-1-RR)

    WB analysis using 80127-1-RR (same clone as 80127-1-PBS)

    Non-treated PC-3 and Calyculin A treated PC-3 cells were subjected to SDS PAGE followed by western blot with 80127-1-RR (Phospho-STK11/LKB1 (Thr189) antibody) at dilution of 1:5000 incubated at room temperature for 1.5 hours. The membrane was stripped and re-blotted with GAPDH antibody as loading control. This data was developed using the same antibody clone with 80127-1-PBS in a different storage buffer formulation.

  • Western Blot (WB) analysis of various lysates using Phospho-STK11/LKB1 (Thr189) Recombinant antibody (80127-1-RR)

    WB analysis using 80127-1-RR (same clone as 80127-1-PBS)

    Non-treated NIH/3T3 and Calyculin A treated NIH/3T3 cells were subjected to SDS PAGE followed by western blot with 80127-1-RR (Phospho-STK11/LKB1 (Thr189) antibody) at dilution of 1:5000 incubated at room temperature for 1.5 hours. The membrane was stripped and re-blotted with GAPDH antibody as loading control. This data was developed using the same antibody clone with 80127-1-PBS in a different storage buffer formulation.

    Immunofluorescent analysis of (4% PFA) fixed non-treated PC-3 cells and Calyculin A treated PC-3 cells using Phospho-STK11/LKB1 (Thr189) antibody (80127-1-RR, Clone: 5J9 ) at dilution of 1:200 and CoraLite®488-Conjugated Goat Anti-Rabbit IgG(H+L). This data was developed using the same antibody clone with 80127-1-PBS in a different storage buffer formulation.

  • Flow cytometry (FC) experiment of PC-3 cells using Phospho-STK11/LKB1 (Thr189) Recombinant antibody (80127-1-RR)

    FC experiment of PC-3 using 80127-1-RR (same clone as 80127-1-PBS)

    1X10^6 PC-3 cells untreated (dashed lines) or Calyculin A treated (red) were intracellularly stained with 0.25 ug Anti-Human Phospho-STK11 (Thr189) (80127-1-RR, Clone:5J9) and CoraLite®488-Conjugated Goat Anti-Rabbit IgG(H+L) at dilution 1:1000 (red), or 0.25 ug Control Antibody (blue). Cells were fixed with 4% PFA and permeabilized with 90% MeOH. This data was developed using the same antibody clone with 80127-1-PBS in a different storage buffer formulation.

Background Information

STK11(serine/threonine-protein kinase 11) is also named as LKB1, PJS, and belongs to the protein kinase superfamily. It controls the activity of AMP-activated protein kinase (AMPK) family members, thereby playing a role in various processes such as cell metabolism, cell polarity, apoptosis and DNA damage response. The tumour suppressor protein LKB1 is a serine/threonine kinase that has been causally linked to Peutz-Jeghers syndrome (PJS). Defects in STK11 are a cause of Peutz-Jeghers syndrome (PJS) and defects in STK11 have been associated with testicular germ cell tumor (TGCT) and some sporadic cancers, especially lung cancers.
