Ordering Information

Biological Activity

Ciproxifan Maleate is a potent and selective histamine H3 receptor antagonist with high affinity for the H3 receptor subtype. By blocking presynaptic histamine H3 autoreceptors and heteroreceptors, it enhances histaminergic neurotransmission and promotes the downstream release of neurotransmitters such as acetylcholine and dopamine in the central nervous system. These actions contribute to downstream functional effects including increased wakefulness, enhanced cognitive performance, and modulation of neuronal signaling. [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).
