[0002] In the field of modern medical detection, tumor gene detection has become an important means for early diagnosis of tumors, individualized treatment and prognosis evaluation, and tumor gene detection reagents usually contain nucleic acid probes, fluorescent markers, enzymes, buffers and other biological active substances.

In addition, the existing storage boxes are often not optimized for the special requirements of tumor gene detection reagents, such as preventing reagent degradation, avoiding cross contamination and improving accessibility, etc.
