Figure Lengend Snippet: Figure 2 Expression of VAPB and VAPA proteins in PBL and CSF from healthy (HC) and neurological (NC) controls. (a), (b), (d) Representative immunoblots showing the expression pattern of VAPB (a), (b) and VAPA (d) identified in PBL and CSF. (c) Peptide competition experiments to verify specificity of the anti- VAPB antibody. Western blots were carried out with (a) 100 lg or (b)–(d) 65 lg proteins of extracts. Differences in the molecu- lar sizes of VAPB and VAPA bands are reported in leucocytes. VAPB and VAPA exhibit two close bands that approximate the molecular size of 17 kDa. In CSF, only the 14 kDa band of VAPB was identified in most samples examined, and no VAPA product was detected; in rare instances, a 24 kDa band of VAPB (asterisk) was additionally detected.
