  WB analysis using 80919-2-RR (same clone as 80919-2-PBS)

  Various lysates were subjected to SDS PAGE followed by western blot with 80919-2-RR (Ataxin 2 antibody) at dilution of 1:5000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 80919-2-PBS in a different storage buffer formulation.

Background Information

ATXN2 contains a repeat structure with 22 or 23 triplets coding for glutamine and the (CAG)8CAA(CAG)4CAA(CAG)8 sequence; expansion of this domain to a size ≥34 triplets with a pure CAG sequence primarily causes autosomal dominant SCA2 [PMID:18418684], while ATXN2 expansions with CAA interruptions were observed as the cause of Levo-dopa responsive Parkinson's disease [PMID:10668726]. ATXN2 expansions associated with ALS were reported to be interrupted by at least one CAA triplet [PMID:21537950]
