ALCAM and kidney injury: To assess the specificity and cross-reactivity profiles of the ALCAM LFA and HVEM LFA tests, ALCAM or HVEM (which should yield positive results in the respective LFAs) and various other LN irrelevant proteins that may be present in kidney injuries and cancer relevant proteins, were tested for their signals when applied to these LFAs (which should yield significantly lower signal than positive strip) in Figure 7A.
