Biotium MUC5AC (Mucin 5AC / Gastric Mucin)(2-12M1), CF740 conjugate, 0.1mg/mL

This MAb recognizes the peptide core of gastric mucin M1 (recently identified as Mucin 5AC). Its epitope is located in the N-terminal cysteine rich part of the peptide core of MUC5AC, which is heavily glycosylated. Its epitope is destroyed by beta-mercaptoethanol but not by periodate treatment. MAb 2-11M1 reacts with the protein backbone exclusively; it only reacts with fully deglycosylated MUC5AC. Therefore, the material under test should also be fully deglycosylated. This can be achieved with standard periodate oxidation method. The success of the deglycosylation can be checked with routine PAS (Periodic Acid Shiff) staining. After deglycosylation, the preparation should no longer be stainable with PAS reagent. Only then 2-11M1 will react should MUC5AC be present. This mucin is present in primary ovarian mucinous cancer but usually absent in colorectal adenocarcinoma, thus showing an expression pattern opposite to MUC2. Together with a panel of antibodies, Anti-MUC5AC may b

endo-BCN-PEG2-C2-NHS ester is a PEG-based PROTAC linker used in the synthesis of PROTACs. PROTACs consist of two different ligands connected by a linker, where one ligand targets an E3 ubiquitin ligase and the other targets a protein of interest. This mechanism exploits the intracellular ubiquitin-proteasome system to selectively degrade target proteins.

• PEG-based PROTAC linker
• Used in the synthesis of PROTACs
• Exploits intracellular ubiquitin-proteasome system
• Selectively degrades target proteins
