特異性:This assay has high sensitivity and excellent specificity for detection of Human CK-18/KRT18. No significant cross-reactivity or interference between Human CK-18/KRT18 and analogues was observed. Note: Limited by current skills and knowledge, it is impossible for us to complete the cross- reactivity detection between Human CK-18/KRT18 and all the analogues, therefore, cross reaction may still exist.
