In Vitro

Licarin A is found in plants such as Aristolochia taliscana, Machilus thunbergii and Myristica fragrans, which are used as spices and in folk medicines for nervous and digestive disorders. Licarin A also exhibits anti-inflammatory effects^[1].
Licarin A (5-20 μM) reduces TNF-α and prostaglandin D2 (PGD2) secretion via the inhibition of PKCα/βII and p38 MAPK pathways. Licarin A treatment tends to reduce phosphorylated PKCα/βII and p38 MAPK protein levels^[1].

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.
