In vitro evaluation of mAb62 for efficient targeting and monitoring of tumours was performed with the MDA-MB-435S cell line, which is known to express Kv10.1 and which was used by our group in previous in vivo studies (Gomez-Varela et al. 2007; Downie et al. 2008; Hartung and Pardo 2016). Here, KCNH1 is linked to neoplasm.
