Letosteine (Standard)

Letosteine (Standard) is the analytical standard of Letosteine (HY-107355). This product is intended for research and analytical applications. Letosteine is an orally active, potent and safe expectorant. Letosteine has the effect of scavenging reactive oxygen species (ROS). Letosteine dissolves bronchial mucus and reduces respiratory inflammation symptoms, and restores gas exchanges and natural defense mechanisms in the lung. Letosteine can be used for acute or chronic respiratory diseases (such as bronchopneumopathies) research.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
