Based on 1 Customer Validation

Montelukast (Standard) is the analytical standard of Montelukast. This product is intended for research and analytical applications. Montelukast (MK0476 free base) is a potent, selective and orally active antagonist of cysteinyl leukotriene receptor 1 (CysLT₁). Montelukast can be used for the reseach of asthma and liver injury. Montelukast also has an antioxidant effect in intestinal ischemia-reperfusion injury, and could reduce cardiac damage. Montelukast decreases eosinophil infiltration into the asthmatic airways. Montelukast can also be used for COVID-19 research.

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.
