Updated project metadata. This project aims to identify the proteins present in RNA granules of brown adipose tissue upon exposure to cold challenge. Wild type C57BL/6J mice were born and raised at thermoneutrality and were then subjected to cold exposure for 90 minutes. Brown adipose tissues were collected, and the protein lysates of RNA granules isolated from the brown adipose tissues were separated using SDS-PAGE gels and visualized with Coomassie stain. The protein bands were subsequently excised for downstream sample processing.
