Individual Quick Frozen products are produced in one of two ways, they can be placed in an immersion of liquid nitrogen at the very low temperature of minus 196 C to freeze the main outer surface. Department of Pathology, School of Medicine, Chiba University, Chiba 260, Japan. File away any burrs on the side of the steel you plan to etch with acid. Mol. We also noticed that SH1–SH2 cross-linked myosin gives an aberrant appearance similar to the above structure. Quick‐Freeze, deep‐etch studies of renal basement membranes. Air abrasion technique was significantly better than This site, and the information here, is primarily the inspiration of Norm & Ruth Dobbins of Professional Glass Consultants and EtchMaster in Santa Fe, New Mexico, USA. Briefly, the tissue is very rapidly frozen, fractured and then ‘‘etched’’ by a process in which vitrified water is sublimated away at the fractured surfaceTechniques For Studying Cytoskeleton Electron Microscopy. Quick-freeze/deep-etch is a technique that has been shown to better preserve the ultrastructure of the extracellular matrix as compared to conventional techniques @8#. The membranes of adjacent secretory granules were partially fused at their contact sites where intergranular strands were no longer seen, while there existed intergranular strands between unfused portions of the granule membranes. 26 . actin gels [18] and steroid=cyclohexane gels [2~].

Whether these through-going holes were pre-existing flaws or artifacts of the freeze-fracturing is uncertain. Method 1/thin sectioning +/- immuno. Example: A fibroblast cell is prepared by the quick-freeze-deep-etch method. J. (1983) 169, 97-122 Actin-Myosin Interactions Visualized by the Quick-freeze, Deep-etch Replica Technique J. E. AND R. The quick-freeze, deep-etch, rotary-replication technique effectively bridges the gap between thin-section and freeze–fracture views. After quick-freezing of whole cells, cell fragments (bacteria) or isolated organelles, they need not be cryofractured and replicated with platinum, but instead can be freeze- substituted at –80 C and imbedded in plastics for traditional thin sectioning. Quick-freeze deep-etch electron microscopy of the dynamin-microtubule complex showed that dynamin decorates the surface of microtubules helically, like a screw bolt, very orderly and tightly with 11.
