I intend to label monosaccharide (eg: fucose) so that I can quantify
them eventually. However, I only came across DTAF from Molecular
Probes which can label polysaccharides. Does anyone, by any chance,
used this labeling process before or know of other ways of labeling

what does a CO2-Incubator serve for?
For what is the CO2-zero-cycle?

Dear colleagues,
Hello,I am new to this group,i wonder if some one could guide me in
basic of PLANKTON growth in water( sea ,brackish and Fresh water)
Sodium nitrate

I'm a Greenhorn to this group but I hope anyway that you can help me.
At the moment I deal with yeast (esp. Saccharomyces cerevisiae) and I
have quite a big problem to get any data about heat inactivation of
their Ascospores.

Mesdames, messieurs les biologistes et techniciens,
Je suis à la recherche de lames de parasites sanguicoles ou autres
pour montrer à mes étudiants de BTS analyses biologiques pour la
rentrée scolaire prochaine.

Hello
Just have a question that is related to bio chemistry. Some people I
know have a chemical or bacteria that is eather in liquid of gas form
that after it is released it makes the person scratch their nose or

Why is it that cold (but NOT freezing) kills so many animals and
plants?
Why would a cold-induced slowing of metabolism cause the catastropic
break-down of cellular functions necessary for continued life?

How does low, but not freezing, temperatures kill cells & organisms?
Just curious.

Hey everyone. Thanks to everyone who offered advice on how to make thin
sections of thalli. I ended up using my forceps as a crude vise to hold
the thallus in position, and I used a sharp, thin, steel razor blade to
slice it. The added advantage of the forceps was that they acted ...

I need some articles on latest techniques used in Bacterial
Identification that are used in Clinical Pathology lab and are capable
of definitive diagnosis of eye infections.  Thanks

My lab is currently conducting assays to estimate antibiotic depletion
in various tissues. The method, however, seems clumsy and a bit
imprecise. Essentially, we inoculate agar with _Bacillus cereus_ and
then sink penicylinders into it (by hand, so how deep they go is

Would someone actually send along the name of a laboratory or names of laboratories
that would test needles, syringes for infectious organisms, a laboratory where a doctor
could have a needle, syringe tested in a case where the test results make a
difference in treating the patient ...

Can you tell me a metodology to determinate the expiration date for food by
micobiological side (by total count, water activity, pH etc.)
thanks
