Additional file 1 of Rapid quantification of trastuzumab and bevacizumab in serum using magnetic bead immuno-enrichment coupled with LC–MS/MS

Supplementary Material 1: Fig. S1. Linearity Assessment of Calibration Curves for Trastuzumab and Bevacizumab. Calibration curves for trastuzumab and bevacizumab (1–500 µg/mL). Both curves are linear with R² >0.999 (equations shown inset), confirming the method’s broad linear range.
