Abstract
Clathrin coated vesicles (CV) from bovine brain were analyzed via Western blots for the presence of the alpha and beta subunits of guanine nucleotide regulatory proteins. The results with the common alpha antibody GA/1 revealed the presence of apparently undissociated G-protein subunits migrating at approximately 80 kDa. The predominant band was of about 39-41 kDa, with minor labeling observed in the 41-52 kDa range. Western blot analysis for G beta subunit(s) revealed the presence of a single band of about 35-36 kDa.
