Deletion of asparagine 312 allows for secretion of full-length recombinant α dystroglycan (αDG) from CHO and CHO-LARGE cells.

Deletion of asparagine 312 allows for secretion of full-length recombinant α
dystroglycan (αDG) from CHO and CHO-LARGE cells.

A plasmid encoding a full-length αDG cDNA (wild type, WT) with a FLAG epitope tag at the N-terminus, or various asparagine deletion mutants (dR), were transfected into CHO or CHO-LARGE cells and proteins purified from the supernatant using anti-FLAG agarose. Proteins were detected by immunoblotting for αDG using antibody to FLAG, αDG (IIH6 or VIA4-1) or by laminin α2 (LNα2) protein overlay.
