Specificity
Detects human sFRP-2 in direct ELISAs and Western blots. In direct ELISAs, 100% cross-reactivity with recombinant mouse (rm) sFRP-2 is observed and no cross-reactivity with recombinant human (rh) sFRP-1 or rhsFRP-5 is observed. In Western blots, no cross-reactivity with rhsFRP-1, -4, -5, or rmsFRP-2 is observed. 100% cross-reactivity with rhsFRP-3 is observed under non-reducing conditions only.
