Product Usage Information

Erlotinib is supplied as a lyophilized powder. For a 10 mM stock, reconstitute the 10 mg in 2.54 ml DMSO. Working concentrations and length of treatment can vary depending on the desired effect, but it is typically used as a pretreatment at 0.1-10 µM for 0.5-2 hours prior to treating with a stimulator. It can also be used alone, with varying treatment times lasting up to 24 hours. Soluble in DMSO at 100 mg/ml, soluble in ethanol at 10 mg/ml with warming; very poorly soluble in water with a maximum solubility ~5-20 µM.

Storage

Store lyophilized or in solution at -20ºC, desiccated. In lyophilized form, the chemical is stable for 24 months. Once in solution, use within 3 months to prevent loss of potency. Aliquot to avoid multiple freeze/thaw cycles.

Background

Erlotinib is a novel and potent ATP-competitive inhibitor of the EGFR kinase pathway. It inhibited EGFR autophosphorylation with an IC₅₀ of 20 nM in vitro and inhibit purified EGFR kinase with an IC₅₀ of 2 nM (1). Erlotonib is greater than 1000-fold more selective for EGFR than c-src and v-abl (1), ErbB-2, and ErbB-4 (2). Studies have shown that erlotinib inhibits growth and induces G1 cell cycle arrest in multiple cell types, many of which overexpress EGFR (1,3-5).

This product has applications to SARS-CoV-2 research into the mechanisms of the Novel Coronavirus, which has caused the COVID-19 pandemic.
