IC₅₀ & Target

Complement C1s

In Vitro

Co-incubation of DNTH103 (0.1 μM, 1 μM) with complement-containing serum from AChR-positive myasthenia gravis patients significantly reduces the muscle contraction fatigue index and improves neuromuscular transmission function in a human iPSC-derived motor neuron-muscle cell co-culture myasthenia gravis model. Its efficacy is superior to that of anti-C5 antibody at the same concentration, and it exerts no significant effect on serum samples from healthy individuals^[3].

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.
