Colocalization analysis was performed using the Manders coefficient, which revealed that in glioma cells, similarly to B cells, CD150 was colocalized with the endoplasmic reticulum for both ER markers: kinectin-1 (Manders coefficients 0.65±0.03 and 0.69±0.03 respectively; n = 7) and GRP78 (Manders coefficients 0.61±0.05 and 0.68±0.03 respectively; n = 7). This evidence concerns the gene KTN1 and glioma.
