Glutaraldehyde Fixative (4%, For Electron Microscopy)

Guideline (The following is our recommended protocol. This protocol is only a guideline and should be modified according to your specific needs).
1. Take fresh samples and immediately add them to Glutaraldehyde Fixative. Fix at 4°C for 1-4 hours. If the sample is thick, the fixation time can be appropriately extended.
2. Fixed samples can be tested immediately or stored at 4°C.
Note:
1. Glutaraldehyde Fixative is corrosive. Please handle in a well-ventilated environment and avoid contact and inhalation.
2. Routine samples generally require a thickness of 2-4 mm, preferably not exceeding 6 mm.
3. The volume ratio of fixative to sample tissue block should be greater than 10:1 to ensure the sample is completely immersed in the fixative.
4. Glutaraldehyde Fixative is normally colorless or light yellow. If the color deepens, it should be discarded.
