Physical form

Format: Purified
Subsequent thiophilic adsorption and size exclusion chromatography
lyophilized in 2X PBS containing 0.09% sodium azide, PEG, and sucrose.

Preparation Note

2 years at -20°C from date of shipment. Reconstitute prior to use. Reconstitute with 1 mL H2O for 15 min at room temperature. Reconstituted aliquots should be stored frozen at -80°C. Thawed aliquots may be stored at 4°C for up to 3 months. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance.

Analysis Note

Control
EGF treated SKOV-3 lysates
Routinely evaluated by immunoblot.

Human epidermal growth factor receptor 2 (HER2) is an oncogenic driver and key therapeutic target for human cancers. Current therapies targeting HER2 are primarily based on overexpression of the wild-type form of HER2. However, kinase domain mutations have been identified

Autocrine EGF-receptor (EGFR) ligands are normally made as membrane-anchored precursors that are proteolytically processed to yield mature, soluble peptides. To explore the function of the membrane-anchoring domain of EGF, we expressed artificial EGF genes either with or without this structure
