Check if the same lab product or an alternative is used in the 5 most similar protocols
Lysates made from quadriceps skeletal muscles collected from GEMM KPC mice and the sex‐matched and age‐matched genotype control mice at early and late tumour stages were subjected to western blotting. The primary antibodies used were ubiquitin (3933) and phosphor‐Stat3 (9145) from Cell Signalling Technology, Danvers, MA, USA, and GAPDH (ab9484) from Abcam, Cambridge, MA, USA. The secondary antibodies used were IRDye 800CW goat anti‐rabbit IgG (926‐32211) and IRDye 680LT goat anti‐mouse IgG2b‐specific (926‐68052) from LICOR Biosciences, Lincoln, NE, USA. Signal was detected using a LI‐COR Odyssey system.

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.
