Biological Activity

Carrageenan (kappa-Carrageenan) is a natural sulfated polysaccharide derived from edible red seaweeds that exhibits potent antiviral activity by inhibiting viral entry as well as immunomodulatory and anti-tumor properties. By disrupting viral cell attachment and modulating host immune responses, carrageenan limits pathogen infection and tumor progression, supporting its use in animal models of inflammatory conditions such as prostatitis.

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).
