DTME (dithio-bis-maleimidoethane) is a homobifunctional, maleimide crosslinker specifically designed for conjugation between sulfhydryl groups (-SH). DTME, whose molecular structure consists of two maleimide groups connected by an ethylene disulfide bridge, can specifically react with thiol - containing molecules (such as cysteine residues) to form stable covalent bonds. DTME allows crosslinks that can be cleaved with reducing agents such as DTT (HY-15917). DTME is commonly utilized to explore and characterize protein structure, particularly oligomerization, or protein interactions .

Infection

N-Succinimidyl bromoacetate (NHS-Bromoacetate) is a heterobifunctional crosslinking reagent, mainly used to modify the ɛ-amino group of lysine side chains. By covalently linking its bromoacetyl moiety to the ɛ-amino group of lysine in peptidomimetics, N-Succinimidyl bromoacetate enables their conjugation with thiol-modified nanoparticles via thioether bonds. N-Succinimidyl bromoacetate also performs bromoacetylation modification on carrier proteins, which then forms stable thioether bonds with the thiol groups of cysteine in peptides, thus efficiently preparing soluble peptide-protein conjugates with high substitution ratios. N-Succinimidyl bromoacetate can be used to prepare activated Sepharose derivatives for affinity chromatography, protein affinity labeling reagents, and peptide-protein immunogen conjugates with non-immunogenic linkages. N-Succinimidyl bromoacetate is applicable to studies related to HIV-1 infection and glioblastoma multiforme .

DOPE-Mal is an N-maleimide-derived phosphatidylethanolamine. DOPE-Mal does not interfere with fatty acyl chains or alter lipid bilayer permeability; it increases lipid bilayer order, reduces fluidity, induces conformational changes in phospholipid polar heads and enhances their hydration. DOPE-Mal can be used as a component to prepare maleimide-displaying liposomes, enabling peptide conjugation via maleimide-thiol coupling. DOPE-Mal can be used to prepare Liposomes for delivering Doxorubicin (HY-15142A) to hepatocytes. DOPE-Mal is applicable to research related to hepatocellular carcinoma and lung cancer .

BCN-E-BCN is a strained cycloalkyne-based probe designed for detecting protein sulfenylation, the primary intermediate in protein oxidation. This structurally constrained cycloalkyne compound specifically recognizes sulfenic acid groups formed during thiol oxidation, while remaining completely unreactive toward other oxidative states (such as free thiols, sulfinic, or sulfonic acid groups). Researchers can leverage its efficient conjugation with azide-bearing tags through copper-free click chemistry to amplify detection signals. Compared to conventional detection methods, BCN-E-BCN demonstrates superior reaction kinetics and enhanced sensitivity. With these advantages, BCN-E-BCN shows great promise as an effective tool for protein oxidation research .
