Figure S1 from Triple Therapy with MerTK and PD1 Inhibition Plus Radiotherapy Promotes Abscopal Antitumor Immune Responses

High dose RT induced higher apoptosis. Mice were inoculated in the right leg with 344SQ for establishment of primary tumor. Tumors were treated locally by intermediate dose RT (15 Gy in three 5-Gy fractions) or High dose RT (36 Gy in three 12-Gy fractions). Tumors were harvested 7 days after the last fraction of RT then sectioned for Immunohistochemistry using Caspase-3 staining.
