In this procedure, we describe a high‐throughput absolute quantification protocol for the protein‐bound sulfur amino acids, cysteine (Cys) and methionine (Met), from plant seeds. This procedure consists of performic acid oxidation that transforms bound Cys into cysteic acid (CysA) and bound Met into methionine sulfone (MetS) followed by acid hydrolysis. The absolute quantification step is performed by multiple reaction monitoring tandem mass spectrometry (LC‐MS/MS). The approach facilitates the analysis of a few hundred samples per week by using a 96‐well plate extraction setup. Importantly, the method uses only ∼4 mg of tissue per sample and uses the common acid hydrolysis protocol, followed by water extraction that includes DL‐Ser‐d3 and L‐Met‐d3 as internal standards to enable the quantification of the absolute levels of the protein‐bound Cys and Met with high precision, accuracy, and reproducibility. The protocol described herein has been optimized for seed samples fromArabidopsis thaliana,Glycine max, andZea maysbut could be applied to other plant tissues. © 2023 Wiley Periodicals LLC.Basic Protocol: Analysis of protein‐bound cysteine and methionine from seeds
