While we know from our experiments that our AMPKα Antibody #2532 can detect both the alpha1 and alpha2 isoforms of the catalytic subunit, these should both run above 60kDa. We do occasionally see some non-specific banding around 50 kDa or lower. However, this appears to be very sample dependent and can often be titrated out by loading less lysate. The specific AMPKα signal should be a prominent band around 62kDa.

Webinar featuring Reuben Shaw, Professor at the Molecular and Cell Biology Laboratory, Deputy Director of Salk Cancer Center, Salk Institute for Biological Studies.
In this webinar, Dr. Reuben Shaw will explore new findings in the field of AMPK and Autophagy signaling.
Several different assays can be used by scientists to measure metabolism in a variety of contexts. These include methods to determine metabolic rates, key signaling pathways, and environmental cues.
In-house, we tested AMPK Control Cell Extracts #9158 and mouse liver extract, blotting with AMPKα2 Antibody #2757 (approved for human and monkey) and a competitor AMPKα2 antibody (approved for mouse reactivity). We observed no signal with AMPKα2 Antibody #2757 in the mouse extracts, confirming AMPKα2 Antibody #2757 is not approved for mouse reactivity. Blotting with the competitor antibody we observed very weak signal in AMPK Control Cell Extracts #9158 and strong signal in mouse liver extract; therefore, suggesting AMPK Control Cell Extracts #9158 may not be an appropriate control for measuring AMPKα2 levels.
Tumor cells adopt novel mechanisms to acquire nutrients and reprogram metabolic pathways to meet their increased bioenergetics demands. CST provides tools to detect and measure key metabolic changes.
Autophagy helps normal cells maintain homeostasis and acts as a survival mechanism in response to stress, where ULK1 plays an important role in signaling.
If CST recommended buffers are being used for western blotting and high background or additional bands persist when probing for phospho-AMPK (Thr172), the issue could be related to the lysate sample. In general, tissue samples can be prone to high background by western blotting when compared to cultured cell lines, and liver tissue samples (a high expressing model for AMPK) in particular tend to show high background in the form of multiple bands when probing for phospho-AMPK. Sonication and the use of proper buffers for western blotting can help to alleviate this issue in some instances.

Cellular metabolism encompasses all of the chemical processes that occur within cells to maintain homeostasis and define their energetic status. These include anabolism and catabolism.
The Ser485 site detected by our Phospho-AMPKα1 (Ser485) (45F5) Rabbit mAb #2537 has been identified as an inhibitory phosphosite of APMKα1 and will be phosphorylated to a lesser degree when AMPK is activated in response to nutrient-deprived conditions (e.g., serum or glucose starvation). Therefore, you should see a decrease in signal intensity with #2537 in serum-starved samples, such as the positive extract included in our AMPK Control Cell Extracts #9158.

Yes, the flow through from a PTMScan experiment can be saved and stored at -80C for future enrichments. We have performed 5 different PTM enrichments sequentially from one sample. The limitation would be the choice of the initial protease used for the digest. For example, a UbiScan PTMScan requires peptides digested with trypsin and the flow through peptides may not be ideal to capture peptides that require an arginine (R) residue in the phospho-motif as in the AKT or AMPK substrate PTMScan kits.
