Fig 8. Adsorption analysis of cattle saliva proteins.

Fig 8

Adsorption of cattle saliva proteins to cellulose was analyzed using (a) SDS-PAGE and (b) Bradford protein assay. (a) SDS-PAGE analysis. Lane 1: Cattle saliva solution (80%). Lane 2: Supernatant, supernatant after the mixture was incubated at 50°C for an hour. Lane 3: Wash 1, supernatant of Wash buffer 1. Lane 4: Wash 2, supernatant of Wash buffer 2. Lane 5: Wash 3, supernatant of Wash buffer 3. Lane 6: Elute, eluted fraction after the cellulose pellet was mixed with 0.5% SDS and incubated at 96°C for 1 h. (b) Amount of protein in each sample used for SDS-PAGE analysis was quantified by Bradford protein assay. Error bars indicated ± deviations (n = 3).
