Biological Activity
3-Bromotyrosine, a product of protein oxidation, is generated after eosinophil activation during allergic responses. It serves as a biomarker for eosinophil peroxidase-induced protein oxidation both in vitro and in vivo. Beyond its association with eosinophils, 3-bromotyrosine levels are significantly elevated in peritoneal exudate from K. pneumoniae-infected mice, indicating a fivefold increase compared to uninfected controls, which implies that neutrophils may release increased levels of oxidized products during inflammation. Furthermore, in humans, allergen-challenged lung samples from patients with allergen-induced asthma show a tenfold increase in 3-bromotyrosine, highlighting its potential as a marker for oxidative stress in allergic conditions.
Safety & Regulatory
For Research Use Only (RUO). Not for therapeutic, diagnostic, or clinical use. Wear appropriate PPE and consult the Safety Data Sheet (SDS) prior to handling.
Use a bath-type ultrasonic cleaner at standard cleaning frequency (37–40 kHz). Bath sonication is gentler than a probe sonicator and avoids sample overheating. Sonicate in 5–10 second intervals, checking solubility between pulses, for no more than 2–3 minutes total. Warm the bath to 37 °C if solubility remains poor.
Use a bath-type ultrasonic cleaner rather than a high-intensity ultrasonic disruptor. Bath sonicators provide gentle, uniform agitation appropriate for dissolving solid compounds without generating cavitation damage or excessive heat. Ensure the solvent tube is fully submerged and use short sonication pulses of 5–10 seconds.
