特異性:Most polyclonal CEA antisera show cross-reactivity with related antigens such as biliary glycoprotein (BGP) and non-specific cross-reacting antigen 1/11 (NCA). PARLAM 4 does not show cross reactivity, neither with BGP nor with NCA. In immunoblotting the antibody recognizes a single band of 180 kD.
形状:Each vial contains 100 ug 1 mg/ml purified antibody in PBS + 0.09% sodium azide.
