Furthermore, the engineered cells displayed bothintracellular and secreted LGALS3BP levels comparable to those ofSKNAS neuroblastoma cells, which endogenously express the protein.Importantly, we confirmed 1959 antibody specificity trough confocalmicroscopy analysis in which cell surface and cell milieu were specificallylabeled in hNB LGALS3BP but not in control cells (Figure D). Here, LGALS3BP is linked to neuroblastoma.
