Go-alpha. Strong reactivity with bovine (100%), human (70%), rat (61%) and mouse (54%). Slight reactivity with guinea pig (27%). Specificity confirmed by Western blot versus bovine G-alpha-t, rat Go-alpha, rat Gi-alpha-1, Gi-alpha-2, rat Gi-alpha-3, bovine Gs-alpha, and murine Go-alpha-A and Go-alpha-B. The carboxy-terminal splice variants of Go-alpha (Go-alpha-A and Go-alpha-B) expressed in bacterial lysates were compared for reactivity and found to be equal . As Go-alpha-A and Go-alpha-B have >95% homology to rat Go-alpha-1 and human Go-alpha-2, MAB3073 will detect these G-proteins also.


Bovine brain Go-alpha purified by the method of Sternweis and Robishaw (J. Biol. Chem. [1984] 259, 13806).
