Catalyzed Reported Deposition-Fluorescence In Situ Hybridization Protocol To Evaluate Phagotrophy in Mixotrophic Protists
Abstract We describe a catalyzed reported deposition-fluorescence in situ hybridization (CARD-FISH) protocol particularly suited to assess the phagotrophy of mixotrophic protists on prokaryotes, since it maintains cell and plastid integrity, avoids cell loss and egestion of prey, and allows visualization of labeled prey against plastid autofluorescence.
This protocol, which includes steps such as Lugol's-formaldehyde-thiosulfate fixation, agarose cell attachment, cell wall permeabilization with lysozyme plus achromopeptidase, and signal amplification with Alexa-Fluor 488, allowed us to detect almost 100% of planktonic prokaryotes ( Bacteria and Archaea ) and, for the first time, to show archaeal cells ingested by mixotrophic protists.
Over the last decade, fluorescent in situ hybridization (FISH) has been increasingly used to identify microorganisms without previous cultivation in aquatic environments (2, 7, 41 ).
A variant of this method, the catalyzed reported deposition (CARD)-FISH, has improved the detection of small bacteria with low ribosome content by using horseradish peroxidase (HRP)-labeled probes (28, 32 ).
FISH techniques have also been applied in studies on endosymbiontic prokaryotes in protozoans (3, 13, 19 ) and phytoplankton (1, 5 ) and to assess protist grazing by quantifying the bacteria in food vacuoles of both ciliates (8, 9, 16 ) and heterotrophic flagellates (21 ).

Fish Protocol roundup
So here is a roundup of the thread: Pavel Machek pointed to "README.fish in vfs/." Joerg Walter wrote: A copy of the original documentation is in the README.
I made some minor extensions to the protocol which should be easy to figure out if you take a look at the perl server.
Pavel Roskin wrote: I believe that the protocol implemented by mc allows the other side to be controlled by a dedicated server instead of a shell, but the fish server has never been implemented.
By the way, if you cannot easily find some software (like fish server), you should not consider it secure even when you find it.
And Pavel replied: I believe that the idea of "fish server" was something that would interpret the shell comments, not the shell commands.
Look for "command" in vfs/fish.c and you will find all you need.

KDE passwords for FISH protocol
At one point, I typed in the wrong password during a FISH session, and checked the "Remember password" box.
Generally the storing between sessions is a great feature, but in this case it keeps me permanently out! This may be an ssh problem, but I can access the remote system using ssh and sftp with no problem; it's just the fish protocol that's using the stored password.

Laboratory Investigation - Improved Sensitivity for Cell Mapping of Hepatitis C Virus RNA Sequences and Cellular Surface Antigens in Blood Cells
When analyzing blood cells, erythroblast-specific markers may be used for flow sorting and then, isolated cells may be studied for the presence of a specific RNA by fluorescent in situ hybridization (FISH).
To solve these problems we have developed an alternative method that allows for the simultaneous detection of nucleic acids by FISH and cell-specific proteins by conventional immunocytochemistry in unfixed agarose gel trapped cells (AGTC).
The second aliquot of cells was processed for the AGTC-FISH protocol.
The specificity of the FISH was assessed by digestion of the cell preparations with RNase A (0.2 mg/ml) (Sigma, St.
After the successful detection of the targeted cells was confirmed by fluorescence microscopy, the slides were processed for AGTC-FISH, as described above..
However, the AGTC-FISH shows that the virus invariably maps on the cell cytoplasm.
The area and the fluorescence intensity rendered by AGTC-FISH was 50 times higher than in cells fixed in paraformaldehyde (data not shown).
