Knock-out validation of commercial C9orf72 antibodies indicated for Western blot. Immunofluorescent Western blot images showing nine commercial C9orf72 antibodies tested at concentrations recommended by the manufacturer. A band of ~ 52 kDa corresponding to C9orf72 (in green) was present in 2-week-old iPSC-derived motor neurons from a C9orf72 ALS/FTD patient, but absent in the KO line only for antibodies GTX632041, GTX634482, 2575-1-AP and B01-5F2. C9 = Pooled technical replicates (wells) of 2-week-old C9 ALS/FTD patient iPSC-derived motor neurons. KO = Pooled technical replicates (wells) of 2-week-old homozygous KO iPSC-derived motor neurons. Membranes were co-incubated with beta-actin loading control (42 kDa, in red).
