News Finding: "If we take XMAP215 out, not a single microtubule forms.
Paper Finding: The experimental results and trends were reproducible exactly, as indicated in respective figure legends.
News Context: Using the pure extractions of each protein, Petry's team was able to see that in a test tube, neither protein can nucleate microtubules without the other. "If we take XMAP215 out, not a single microtubule forms. If you take g-tubulin out, not a single microtubule forms," Petry said.
Paper Context: Therefore choosing one field of view for each reaction was representative and sufficient such that clear differences between samples were observed by imaging these large fields of view. The experimental results and trends were reproducible exactly, as indicated in respective figure legends. All fields of view (132x132um) were homogeneous and measurements from one field of view with another were consistent.
