Protocol tips

Upstream tips	Protocol tips	Downstream tips
-Store the unopened kit at 2-8 °C. -Bring all reagents to room temperature before use. -Reconstitute the Human Cytochrome c Standard with deionized or distilled water. Allow the standard to sit for a minimum of 15 minutes with gentle agitation prior to making dilutions.	-When mixing or reconstituting protein solutions, always avoid foaming. -Substrate Solution should remain colorless until added to the plate. -Keep Substrate solution protected from light. -Stop Solution should be added to the plate in the same order as the Substrate Solution. -Wells that are green in color indicate that the Stop Solution has not mixed thoroughly with the Substrate Solution.

Publication protocol

Blood samples of 337 patients who were referred for curative or palliative external beam thoracic radiotherapy for non-small cell lung cancer were collected. The concentration of osteopontin (OPN), vascular endothelial growth factor (VEGF), erythropoetin (EPO), high mobility group box 1 protein (HMGB1), insulin-like growth factor 1 (IGF-1) and platelet-derived growth factor (PDGF) in serum were measured by ELISA assay and the prognostic potential was assessed using univariable and multivariable survival models.
