In a biology class once we were shown a video of a toad I believe it
was, that could become frozen and then return to normal functioning
after dethawing.
Could this capacity be given to other species? What practical obstacles

Can someone tell me any web links about downloadable analytical methods for
food microbiology or also some tecnhic guideline?
thanks

I have a question regarding the Endospore staining procedure. We had an
exam in our Microbiology class, and we had to list all functions of
each of the steps in endospore staining. I did not put water as a
decolorizer, because it was never listed as such as all the other

Last year I announced in this group the availability of a new
experimental music video DVD that I produced, entitled "Microscopic
Horrors."  This was a music video - partly educational and partly a
parody of 50's sci-fi / horror flicks - of live microscopic organisms

Sir Alec Jeffries is the British geneticist who discovered the DNA
fingerprint two decades ago. His accidental revelation made it possible to
identify people by detecting variations in their genes, changing forensic
science, criminal justice and paternity cases around the world. ...

I wonder if anyone has a protocol for recombination of genes between
two strains of E. coli by using a standard P1 cross?
Thank you.

Hai!
I have a method to isolate anyones DNA in 2 minutes. I have tried this
out many many times and I want to know how far it will be useful
practically. All you have got to do is gargle your mouth with salt

I recently visited the link:
http://www.koshlandscience.org/exhibitdna/inf01.jsp?referrer=Google.
which describes how the use of a virus chip allowed the SARs virus to
be identified as a common source of illness among the infected.

A bit of advice required - if anyone can help.
Can DNA be stored long term as a dry pellet? Or, what are the best
conditions?

First, thanks to everyone who submitted advice on the PCR lab!
Your comments were helpful and informative.
Perhaps one last question....
Can someone provide either the name of or the recipe for a solution to make

Could someone direct me to link(s) that would help understand the
methods used to identify the SARs virus? I tried googling the topic and
searching it on pbs.org, but the results returned were not immediately
helpful.

Greetings all
I want to express an high activity alkaline phosphatase in E. coli. Anyone has an idea for high activity AP gene that work in E. coli? I know Roche got a recombinant version of the bovine AP but I could not find any reference as to how it was done.
Thanks Yoram

We're looking at buying some new uv/vis specs soon, and I'm looking at
the options at the moment... does anyone know if there's a spec in which
continuous growth curves can be measured and plotted, rather than taking
an aliquot and measuring it at intervals? The bugs we need to ...

I am doing research into the motion of cilia and have been searching for a
video/movie with speed and resolution high enough for me capture images
showing a cilium going through its full stroke. Most of the videos I have
found are too choppy and/or just not filmed at a high ...
