In Vitro

SKLB-163 (0-20 μM, 48 h) inhibits proliferation and migration of nasopharyngeal carcinoma (NPC) cells, and sensitizes cells to irradiation^[1].
SKLB-163 (0-20 μM, 48 h) shows cytotoxicity effect in A375, SPC-A1, SW620, HeLa, PC-3 cells^[2].
SKLB-163 (0-2.5 μM, 48 h) induces A375 cell apoptosis and inhibits colony information^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

SKLB-163 (25-100 mg/kg, i.g., once daily for 30 days) inhibits tumor growth and ascites formation, and inhibits liver and lung metastasis in NPC lung metastatic mice model^[1].
SKLB-163 (50 mg/kg, once daily. from the 6th day of SKLB-163 administration, 3 Gy radiation once per day for 3 days) sensitizes NPC tumor to irradiation in CNE-2 and C666-1 subcutaneous xenograft mice models^[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.
