Manstein crouched in the animal room for a long time, so long that when Fritz returned from the low-temperature freezer room, he thought Manstein had fallen asleep.
"Manstein?" Fritz stood at the door, holding a frost-covered foam box, "Are you okay?"
Manstein stood up, his knee clicking. He stretched his numb leg and took the foam box from Fritz's hand. "All of M21's tissues are here?"
"All here, seventeen wax blocks, eight tubes of frozen tissues, and three slides not fully stained yet." Fritz opened the foam box, neatly packed inside were the labeled embedding boxes and centrifuge tubes, "What do you need me to do?"
"Re-slice, re-stain, use double labeling with Dibutylyte and NeuroD, and add DAPI for nuclear staining. I want to see clearly what these cells really are."
