Anti-total GSK-3β is a primary antibody used to detect the expression of the total glycogen synthase kinase-3 beta (GSK-3β) protein. GSK-3β is a serine/threonine protein kinase that plays a crucial role in diverse cellular processes. This antibody can be used in various immunological techniques, such as Western blotting, to analyze the levels of total GSK-3β in biological samples.

Immunoblotting of Gd-BG Effects on hBMSCs

Check if the same lab product or an alternative is used in the 5 most similar protocols
Immunoblotting was performed to detect the protein expression of hBMSCs. hBMSCs were treated with different concentrations of Gd-BG dissolution for different time points. Briefly, the cells were washed with PBS and then collected in cell lysis buffer. Protein concentration was determined using the bicinchoninic acid assay kit (Cell Signaling Technology, Danvers, MA, USA). For this, 10 µg of the extract was electrophoresed in 10% sodium dodecyl sulfate–polyacrylamide gels and transferred to polyvinylidene difluoride membranes. The membranes were treated with the relative antibodies. Primary antibodies, including anti-β-catenin, anti-p-Akt, anti-total-Akt, anti-p-GSK3β, and anti-total-GSK3β, were provided by Cell Signaling Technology. The membranes were then incubated with a secondary antibody (Cell Signaling Technology). After chemiluminescence, LEICA DM 4000 was used to detect the target bands. The results were normalized to the loading control (GAPDH; BioTNT, Shanghai, China). All samples were measured in triplicate.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
