Figure 3: Immunoblots of proteins from latex and washed rubber particles (WRP) from Hevea brasiliensis (H) and Taraxacum kok-saghyz (B) using monoclonal antibodies raised against four allergenic Hevea proteins. M denotes the molecular weight markers, with their molecular weights to the left of each immunoblot. Molecular weights of the hev b proteins are as follows: Hev b1, 14.6 kD; Hev b3, 24-27 kD; Hev b5, 16 kD; Hev b 6.02, 4.7 kD. The red asterisks denote proteins cross-reactive with Hev b 1.
