It has been used as an analyte in the development of zirconium nanoparticles as probes and matrices for mass spectrometry applications.Formal Name: L-histidyl-L-cysteinyl-L-lysyl-L-phenylalanyl-L-tryptophyl-L-tryptophan,...

D-Ala-D-Ala is the terminal dipeptide moiety of peptidoglycan in bacterial cell walls and a target of certain antibacterial agents. Replacement of D-Ala-D-Ala with D-Ala-D-lactate by the combined activity of the enterococcal gene products VanA, VanH, and VanX reduces the affinity of the antibiotic vancomycin...

M40 is a chimeric galanin-derived peptide and galanin-1 (GAL1) receptor antagonist and GAL2 receptor agonist (Kis = 2.4 and 4.07 nM, respectively). It is selective for the GAL1 and GAL2 receptors over the GAL3 receptor (Ki = 288 nM). M40 induces inositol phosphate accumulation in CHO cells expressing the human GAL2...

Lixisenatide is an agonist of glucagon-like peptide 1 receptor (GLP-1R) and a derivative of exendin-4 (48-86) amide (Cay-11096). It binds to CHO-K1 cells expressing human GLP-1R (IC50 = 1.4 nM). Lixisenatide (100 pM) inhibits Il-1beta- and IFN-gamma-induced apoptosis in INS-1 rat pancreatic beta-cells. It lowers...

Mastoparan 7 is a G protein activator and derivative of the mast cell degranulating peptide mastoparan (Cay-20240). It decreases the affinity of acetylcholine (ACh) to porcine brain muscarinic ACh receptors (mAChRs) when used at a concentration of 30 µM and induces GDP/GTP exchange by Gi in a concentration-dependent...

6XHis-DBCO conjugate is a robust building block to introduce a 6XHis-Tag into a biological molecule through the well-known click chemistry. Both 6XHis alkyne and 6XHis-DBCO conjugate contain an alkynyl group that can be conjugated to azido-modified biomolecules. Compared to 6XHis alkyne, 6XHis-DBCO conjugate...

10XHis succinimidyl ester is an excellent building block to make 10XHis conjugates for developing His tag detection probes and purification tools. It readily reacts with a biomolecule that contains an amino group such as antibodies, peptides and amino-modified oligos. The 10XHis tag is one of the most common His...
