Myelotracker(R), Cy5 conjugate Kit

Myelotracker is a cross-species fluorescent marker which targets lactoferrin to enable precise detection of neutrophils in blood, tissues, and inflammation research. Myelotracker is a peptide-based fluorescent probe designed for the labeling of neutrophils in human and animal samples. By binding to lactoferrin, the major protein stored in neutrophil-specific granules, Myelotracker provides reliable and selective detection of this key immune cell population. Validated in human, mouse, rabbit, and guinea pig neutrophils, Myelotracker is available conjugated to Cy3 or Cy5 fluorophores, enabling seamless use in fluorescence microscopy and flow cytometry. Its dual functionality allows the detection of intracellular granules in fixed samples as well as extracellular lactoferrin released during neutrophil activation, offering unique insights into immune dynamics during infection and inflammation. Importantly, Myelotracker does not activate neutrophils, ensuring that labeling faithfully reflects physiological states without inducing artificial responses. While optimized for neutrophils, Myelotracker has also been observed to label basophils and eosinophils, providing additional opportunities for studying granulocyte biology in inflammatory and allergic conditions.
