Jodi Kantor correctly notes that postage-stamp-sized television screens are incapable of displaying much detail, then asserts that "what the tiny new televisions lose in spectacle, they make up in intimacy" ["The Extra-Large, Ultra-Small Medium," Oct. 30].
Landon Rafe Zumwalt opened up about his decision to resign from Grindr in an open letter published on Medium Dec. 7. .
They were then rinsed in PBS and embedded in tissue freezing medium (OCT), frozen and stored at −70°C until sectioning.
After 7 days, Matrigel plugs were removed, embedded in OCT medium (OCT, Tissue-Teck, USA) and immunohistochemistry was performed using Vectastain Elite ABC kit (Vector Laboratories) followed by anti-CD31 reaction with for microvessel staining.
The tissue was frozen in embedding medium (OCT) by immersion in isopentane cooled in dry ice.
Cryoprotected tissues were embedded in Tissue-Tek embedding medium (OCT compound, Sakura Finetek Inc., Torrance, CA, USA) on dry ice.
The right hemisphere was mounted in optimal cutting temperature medium (OCT, Sakura Finetek, Thatcham, UK) for immunohistochemistry. Brains were cut into 10 micron sections using a cryostat.
The brain tissues were removed, then embedded in tissue-freezing medium (OCT) at –80°C, and stored at –20°C in a refrigerator.
Tissue blocks were frozen in Optimal Cutting Temperature embedding medium (OCT, Sakura Finetek, Torrance, CA, USA) and used to prepare 20 μm sections on a Reichert-Jung 1800 cryostat microtome.
The muscle sample was mounted on embedding medium (OCT compound) and serial transverse sections (10 μm) were cut in a cryostat (2800 Frigocut E, Reichert-Jung, Leica Microsystems GmbH) at -20°C.
The remaining waste tissue from the optimal controlled temperature medium (OCT -embedded cytOCT -embeddedor frozen secytomoldsong with frozen samples of ipsilateral and contralateral benign breast tissusedwere the materials used for this study.
