چکیده

Since the advent of cryo-electron microscopy (cryo-EM), the close-to-life and fine structure preservation of biological samples has become a realized procurement, surpassing the fixation quality and avoiding the numerous artifacts inherent to conventional chemical preservation methods. Cryo-EM techniques such as high-pressure freezing followed by freezesubstitution (HPF/FS) have facilitated the simultaneous immobilization of all supramolecular complexes within a sample within milliseconds, providing a true snapshot of the cell at the moment of freezing.

Tandem high-pressure freezing and quick freeze substitution of plant tissues for transmission electron microscopy.

Since the 1940s transmission electron microscopy (TEM) has been providing biologists with ultra-high resolution images of biological materials. Yet, because of laborious and time-consuming protocols that also demand experience in preparation of artifact-free samples, TEM is not considered a user-friendly technique. Traditional sample preparation for TEM used chemical fixatives to preserve cellu...

Aclar discs: a versatile substrate for routine high-pressure freezing of mammalian cell monolayers.

High-pressure freezing avoids the artefacts induced by conventional chemical fixation, and, in combination with freeze-substitution and plastic embedding, is a reliable method for the ultrastructural analysis of mammalian cell monolayers. In order to high-pressure freeze mammalian cell monolayers, cells have to be seeded on a suitable substrate. Unfortunately, electron microscopy analysis is of...

Ultrastructure of Fat Body Cells of Freeze-susceptible and Freeze-tolerant Eurosta solidaginis Larvae After Chemical Fixation and High Pressure Freezing

In response to low environmental temperatures third instar larvae of the goldenrod gall fly, Eurosta solidaginis, undergo the process of cold-hardening in which they acquire freeze-tolerance. Cold-hardening includes the elevation of the supercooling point, the temperature at which body water spontaneously freezes, and the accumulation of the low-molecular-mass cryoprotectants, glycerol, sorbito...

Evaluation of freeze-substitution and conventional embedding protocols for routine electron microscopic processing of eubacteria.

Freeze-substitution and more conventional embedding protocols were evaluated for their accurate preservation of eubacterial ultrastructure. Radioisotopes were specifically incorporated into the RNA, DNA, peptidoglycan, and lipopolysaccharide of two isogenic derivatives of Escherichia coli K-12 as representative gram-negative eubacteria and into the RNA and peptidoglycan of Bacillus subtilis str...

High Pressure Freezing/Freeze Substitution Fixation Improves the Ultrastructural Assessment of Wolbachia Endosymbiont – Filarial Nematode Host Interaction

BACKGROUND Wolbachia α-proteobacteria are essential for growth, reproduction and survival for many filarial nematode parasites of medical and veterinary importance. Endobacteria were discovered in filarial parasites by transmission electron microscopy in the 1970's using chemically fixed specimens. Despite improvements of fixation and electron microscopy techniques during the last decades, meth...
