Ordering Information

Biological Activity

Isorhamnetin 3-O-neohesperoside is a bioactive flavonoid constituent isolated from Pollen Typhae (Puhuang) with potent antioxidant, antiatherogenic, and antimicrobial activities. It modulates oxidative stress and inflammatory signaling pathways, suppressing ROS accumulation and downregulating pro-inflammatory cytokine expression. These downstream actions mitigate vascular endothelial injury and attenuate atherosclerotic plaque progression, contributing to its protective cardiovascular and antimicrobial phenotypes. [1]

FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
