Mucin Chemical

S2.2 aptamer sodium is a nucleic acid-based MUC1-binding aptamer with high affinity and low toxicity. Upon binding to its target, S2.2 aptamer sodium undergoes a conformational switch and restores fluorescence signal, serving as a targeted imaging agent for MUC1-positive cancer cells. S2.2 aptamer sodium enables targeted delivery to breast cancer cells with overexpressed MUC1. When formulated as the S2.2-PEG-MZF molecular probe, S2.2 aptamer sodium possesses the functions of T2 signal inhibition, magnetic field-induced hyperthermia and targeted magnetic resonance molecular imaging. In the S2.2-PEG-MZF/DOX nanoliposome, S2.2 aptamer sodium supports targeted thermochemotherapy, effectively inhibiting cancer cell proliferation and invasion as well as inducing apoptosis, and is widely used in studies related to breast cancer.

MA3 aptamer sodium is an 86-base long DNA aptamer targeting the mucin MUC1. MA3 aptamer sodium binds to the peptide epitope of mucin 1 (MUC1) with a Kd of 38.3 nM and has minimal cross-reactivity with albumin.
