Descripciòn

In Vitro

CBA-4 (39 μM; 15 min) fully acylates purified Ldt_fm and forms a stable acyl-enzyme adduct that shows no detectable hydrolysis after 3 h of incubation^[1].
CBA-4 (30 min) undergoes copper-catalyzed azide–alkyne cycloaddition (CuAAC) with 3-azido-7-hydroxycoumarin at an initial rate of 0.56 μM min⁻¹, reaching 21% conversion after 30 min of incubation at room temperature^[1].

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.
