Depositor Comments

This plasmid is a variant of pGfa2-nLac (Addgene plasmid #53126) constructed by inserting 3 copies of the gfa2 B segment (Besnard et al. 1991) into the Sma I site just upstream of the basal promoter. It has about 75 times higher activity than pGfa2-nLac in transfected cells, but does not work in transgenic mice; possibly the high level of expression it produces is toxic.
