Figure S4 from PSA Secretion from Single Circulating Tumor Cells of Metastatic Castration-Naïve Prostate Cancer Patients

Key Points

• PSA levels were accurately measured from single circulating tumor cells, highlighting precision in detection.
• The calibration demonstrated a strong correlation with R2 = 0.97, affirming the method’s reliability in measuring PSA.
• The approach involved serial dilutions of PSA proteins analyzed for intensity on PVDF membranes, ensuring a precise quantification technique.
• These findings underscore the importance of accurate PSA measurement in metastatic prostate cancer, aiding in clinical decision-making.
