Antigenic correlations between chicken brain organelles, thymocytes and bursacytes.

Rabbit antisera to chicken whole brain and brain microsomes, synaptic membranes, and synaptic vesicles were used in cytotoxicity and immunofluorescence assays against chicken bursacytes and thymocytes. Brain organelles, bursacytes and thymocytes have shown to possess common antigenic determinants. The common antigen is present in small amounts on thymocytes and can be demonstrated only by immunofluorescence.
