Mg132 z leu leu leu cho

Manufactured by Peptide Institute
Sourced in Japan

MG132 (Z-Leu-Leu-Leu-CHO) is a proteasome inhibitor that blocks the 26S proteasome, a multi-catalytic proteinase complex responsible for the degradation of most cellular proteins. It is a synthetic peptide aldehyde that acts as a potent, reversible, and cell-permeable inhibitor of the proteasome.

Cells of the HEK293 line, culture medium and supplements added to the medium, anti-GAPDH antibody, HRP-conjugated secondary antibody and Alexa Fluor 488- or 546-conjugated IgG were purchased as described in our previous study 36 . An anti-lysozyme antibody with a recognition site of 37-50 was obtained from Abcam (Cambridge, MA), and we created an anti-lysozyme antibody with a recognition site of 49-65 in our laboratory. The latter was used for N-terminal deletion mutants (see below). Anti-GRP78/BiP antibody was from Santa Cruz Biotechnology (Santa Cruz, CA); anti-FLAG antibody and anti-FLAG M2 Affinity Gel were from Sigma-Aldrich (St. Louis, MO). MG-132 (z-Leu-Leu-Leu-CHO) was purchased from Peptide Institute (Osaka, Japan), and other reagents were obtained from Wako Fine Chemicals (Osaka).

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.
