| SpCrossreactivity | Mouse and human CS antigenic peptides are highly conserved in many species: 100% in human, chimp, monkey, rabbit, opossum, canine, feline, horse, bovine, pig, zebra fish, drosophila, frog etc. Antibody cross-reactivity in various species has not been studied. Control peptide, because of its low mol. Wt (<3 kDa), is not suitable for Western. It should be used for ELISA or antibody blocking experiments (use 5-10 ug control peptide per 1 ug of aff pure IgG or 1 ul antiserum) to confirm antibody specificity |
