Damselfly wing muscle cross section

Post by blepharopsis »

Cross section of a damselfly flight muscle stained for F-actin (Texas Red-phalloidin), DNA (TO-PRO-3) and acetylated tubulin (anti-Ac-Tub mAb).

The radial/lamellar organization of sarcomeres (blue/teal) is typical for an odonate tubular muscle; I haven't observed it in any other insect/invertebrate (yet). Bundles of motorneuron axons trunks are shown in red.

Imaged on Zeiss LSM 880. Objective magnification 63x.

All them are excellent images, most interesting and enjoyable.
Any chance of seeing a longitudinal section showing the striations?

Thanks! Sure - they aren't that interesting though :)
