This specimen is obtained from a quick frozen, isometrically contracting asynchronous insect flight muscle that has been freeze substituted, plastic embedded, and thin sectioned
tissue 8 myofibril
The sample was enblock stained using uranyl acetate and tannic acid, and post stained with lead citrate and potassium permanganate
muscle fibril false Lethocerus indicus Water bug asynchronous dorsal longitudinal flight muscle myofibril myooplasm tomography
20 mM MOPS buffer, 5 mM NaN3, and MgCl2, ATP, CaCl2, and EGTA in varying millimolar concentrations
 NEGATIVE
Freeze slammed fibers were freeze-substituted in acetone using a tannic aciduranyl acetate sequence, and ultimately embedded in Araldite-506 for thin-section electron microscopy. Ultrathin (25-30 nm) longitudinal sections were stained by permanganate-lead.

Two tilt series at 90 degrees to one another were first independently aligned using marker-free alignment and area matching. The two resulting tomograms were then merged by patch correlation and volume warp using IMOD. Tomogram computed using weighted back projection.
