DC4 crosslinker, an 18Å mass spectrometry-cleavable crosslinking reagent, features two intrinsic positive charges facilitating the fragmentation of cross-linked peptides into their constituent peptides through collision-induced dissociation or in-source decay. Initial fragmentation leads to cleavage adjacent to the positive charges, enabling the identification of cross-linked peptides as pairs of ions with precise mass separation. Furthermore, the resultant intact peptide fragments can undergo further fragmentation, producing a sequence of b- and y-ions for peptide identification.
DC41SMe is a DC1 derivative that is cytotoxic to Ramos, Namalwa and HL60 / s with IC50s ranging from 18-25 pM. DC1 is a simplified analogue of CC-1065, an antibody conjugate of cytotoxic DNA alkylation molecules, used for targeted treatment of cancer.

Palmitic acid-13C (C1, C2, C3, and C4 labeled) is intended for use as an internal standard for the quantification of palmitic acid by GC- or LC-MS. Palmitic acid is a common 16-carbon saturated fat that represents 10-20% of human dietary fat intake and comprises approximately 25 and 65% of human total plasma lipids and saturated fatty acids, respectively.1,2Acylation of palmitic acid to proteins facilitates anchoring of membrane-bound proteins to the lipid bilayer and trafficking of intracellular proteins, promotes protein-vesicle interactions, and regulates various G protein-coupled receptor functions.1Red blood cell palmitic acid levels are increased in patients with metabolic syndrome compared to patients without metabolic syndrome and are also increased in the plasma of patients with type 2 diabetes compared to individuals without diabetes.3,4
