LP-005

LP-005 is a bifunctional anti-C5 antibody fusion protein with pH-dependent C5 binding properties. LP-005 can simultaneously inhibit activation of the terminal complement pathway and the alternative pathway. LP-005 can be used for research on paroxysmal nocturnal hemoglobinuria (PNH).

For research use only. We do not sell to patients.

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.
