The mouse has less serum, which is easy to form hemolysis. Blood needs to be taken from the celiac artery, and the serum can be separated after standing for detection. The mouse can be divided into many subspecies, including nude mouse, black mouse and white mouse. Taking the white mice as an example, there are strains of A, AKR, BALB/c, RF, SWR, etc. The test kits of mouse-specific strains should be optimized as far as possible.
