Description

Protobioside is a steroidal saponin found in the dry bulbs of Fritillaria pallidiflora Schrenk. Protobioside shows no significant cytotoxic activity against human cancer cells[1].

In Vitro

Protobioside (3-100 μM; 48 h) shows no in vitro cytotoxic activity against human C6 brain glioma cells and human HeLa cervix cancer cells, with an IC50 value greater than 100 μM[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
