Application
Cromakalim has been used:
- as a potassium channel agonist to study its response to an acute increase in downstream pressure in rat lymphatic vessels.[1]
- as a potassium channel opener to study its effects on the release of transmitters from adrenergic nerves in rat vas deferens.[2]
- as a potassium channel activator to study its effects on the release of transmitters from purinergic and cholinergic nerves in the rat detrusor muscle.[3]

The cardiac electrophysiologic effects of the potassium channel activators cromakalim, pinacidil and nicorandil were determined in anesthetized open-chest normotensive dogs using conventional surface electrogram recording techniques. Intravenous administration of cromakalim (0.025-0.5 mg/kg), pinacidil (0.1-2.0 mg/kg) and nicorandil (0.1-2.5 mg/kg) produced

How does the storage temperature relate to shipping conditions?
1 answer-
The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Ambient temperature shipping helps to control shipping costs for our customers. At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment.
