a relatively large body of literature data involving a variety of membrane proteins , membrane types , and irradiation conditions ( electron accelerators or 60co sources , and proteins irradiated in lyophilized form or frozen solution ) was examined , and it was concluded that target sizes of membrane proteins , irradiated in the presence of triton x-100 , should be diminished by a factor of about 24 % to obtain the molecular weight value .
