SpCrossreactivity
There are several variants of amyloid-beta produced by cultured cells. The antibodies employed in the kit are directed against 35-40 (capture antibody) and 1-6 aa of Amyloid beta 1-40 (tracer antibody). Therefore, human AB1-40 variants differing in amino acids at the N-terminus are not detected. Antibody crossreactivity with some AB 1-40 variants was determined:Human AB 1-40 100%Human AB 1-42 <0.1%Human AB 17-40 (P3 form) <0.1%Rat/Mouse AB1-40 <16%Rat/Mouse AB1-42 <1.5%Human ¿ 1-43: DAEFRHDSGYEVHHQKLVFFAEDVGSNKGAIIGLMVGGVVIATSequence of 1-6 aa in AB1-40 is the same in human, pig, monkey, sheep, g. pig, canine, rabbit, bovine, frog and chicken. Since this kit uses 1-6 aa antibody as tracer, it is expected that this kit should detect AB1-40 in these species. Rat/Mouse 1-40 have ?G? at position 5 and it is not detected very well in this kit.
