Calactin

Calactin is a glycoside that can be isolated from Asclepias curassavica L.. Calactin activates caspase-3, caspase-8, caspase-9, and phosphorylates ERK. Calactin induces DNA damage, apoptosis, PARP cleavage, G2/M phase cell cycle arrest, shifts Bax/Bcl-2 expression, and shows anti-proliferation effects in leukemia cells. Calactin can be used for the research of leukemia.

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.
