Based on 8 publication(s) in Google Scholar

Ac2-26 ammonium is the N-terminal peptide of annexin 1, and has anti-inflammatory activity. Ac2-26 ammonium induces a decrease in IKKβ protein in lysosomes by chaperone-mediated autophagy (CMA). Ac2-26 ammonium ameliorates lung ischemia-reperfusion injury. Ac2-26 ammonium also inhibits airway inflammation and hyperresponsiveness in an asthma rat model.

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.
