This Article contains a typographical error in the Materials and Methods section under subheading ‘Immunohistochemistry and scoring’ where,

“Formalin-fixed, paraffin-embedded tumor sections or tumor microarrays were processed and stained with anti-CLDN18.2 mAb, followed by detection with EnVision HRP-labeled polymer anti-rabbit second Ab (Dako K4002) based on standard protocol.”

should read:

“Formalin-fixed, paraffin-embedded tumor sections or tumor microarrays were processed and stained with anti-CLDN18.2 mAb, followed by detection with EnVision HRP-labeled polymer anti-mouse second Ab (Dako K4001) based on standard protocol.”
