Various whole cell extracts (30 μg) were separated by 5% SDS-PAGE, and the membrane was blotted with LRRK1 antibody [C1C2], Internal (GTX107407) diluted at 1:1000. The HRP-conjugated anti-rabbit IgG antibody (GTX213110-01) was used to detect the primary antibody. Corresponding RNA expression data are based on Human Protein Atlas program.
