FIGURE 5. Integrin expression by the chondrocytes.

FIGURE 5

Primary chondrocyte cell surface proteins were labeled with biotin. The cells were lysed, and integrins were immunoprecipitated using specific integrin antibodies as indicated. The immunoprecipitated integrins were separated by SDS-PAGE followed by transfer to a piece of nitrocellulose membrane. The biotin-labeled integrins were visualized by horseradish peroxidase-conjugated streptavidin incubation followed by enhanced chemiluminescence detection. mIgG, mouse IgG.
