In Vitro

NTRK1 is a proto-oncogene in colon cancer, Trk inhibitors have been detected to against a variety of human cancers^[1].
Trk-IN-20 (compound 7mb) (0.031, or 0.018 μM, respectively; 72 h) exhibits strong inhibition against the Larotrectinib-resistant cells with NTRK1-G667C or NTRK3-G696A mutations with IC₅₀s of 0.031 and 0.018 μM, respectively^[1].
Trk-IN-20 (compound 7mb) (9-22 nM; 72 h) inhibits BaF3 murine cells stably transformed with NTRK oncogenic fusions including CD74-NTRK1, ETV6-NTRK2 and ETV6-NTRK3 with IC₅₀s of 15, 22, and 9 nM, respectively^[1].
Trk-IN-20 (compound 7mb) (0.32, 1.6, 8, 40, 200; 6 h) inhibits activation of Trk and its downstream proteins in BaF3-CD74-NTRK1, BaF3-ETV6-NTRK2, BaF3-ETV6-NTRK3 cells^[1].
Trk-IN-20 (compound 7mb) tightly bound to ATP-binding site of TrkA, TrkB, and TrkC with binding constant (K_d) values of 1.6, 3.1 and 4.9 nM, respectively^[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.
