Heterophyllin B is a naturally occurring cyclic peptide isolated from Pseudostellaria heterophylla with potential antitumor properties. It targets human esophageal cancer cells by suppressing cellular proliferation and inducing apoptosis. In vitro studies demonstrate that treatment with Heterophyllin B reduces cell viability and inhibits tumor growth, serving as a promising therapeutic candidate and novel strategy for the management of esophageal carcinoma.

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).
