Biological Activity
Sulfalozine sodium is a sulfonamide antiprotozoal agent targeting dihydropteroate synthase in the folate biosynthesis pathway. By competitively inhibiting dihydropteroate synthase, it disrupts protozoal folic acid synthesis, leading to the suppression of purine production and nucleic acid synthesis. Consequently, this blockade impairs parasite replication and cellular viability, rendering it a useful compound for coccidiosis research involving Eimeria species. [1]

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).
