In Vitro

Panitumumab (2 nM-2 μM, 3 h) inhibits ligand-dependent autophosphorylation in EGFR-expressing NCI-H1975 cells, NCI-H1650 cells and CHO cells^[3].
Panitumumab (0-200 μg/mL, 48 h) inhibits the proliferation of DLD-1 cells^[4].
Panitumumab (80 μg/mL, 24 h) increase beclin-1 (a marker of autophagy) levels in Caco-2 cells and DLD-1 cells^[4].

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

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.
