The utility model provides a frame is preserved to big antibody in batches, include the frame, hang jia liang and hang and press from both sides, hang the both ends of clamp roof beam and connect on the frame, hanging and accompanying a plurality ofly, the equipartition presss from both sides the roof beam around on the two sides hanging. This frame is preserved to big antibody in batches simple structure, the sparingly space utilization of refrigerator -freezer, and heat exchange efficiency is high, has effectively guaranteed the quality of antibody, and the antibody complanation is deposited and is not overstock, and it is convenient that antibody is seeked with stock's information updating.
