Secretory lactoferrins play a crucial rolls at mucosal surfaces as not only antimicrobial molecules in primate as well as human, but as physiological protein. Its multiple functions extended to be one of immunogen could elicited autoimmune disorders. Purified camel lactoferrin (cLfs) from different Saudi camel clans were shown to be a potent immunogen when injected into rabbit. Four rabbit were subcutaneously immunized with different camel clans lactoferrin/Freunds adjuvant. Anti-cLfs potency titration was reach 1:32000 and did not significantly differences between different cLfs. The cross-reactivity level of different anti-Lfs were highly significant, specially between cLfs and bLf/hLf.
