Patti- We're in the process of switching our histology staff to 5 8hr days from the 4 10hr days system. Originally it was implemented to account for long staining and slicing procedures that we specialize in, but improved technology makes that less of an issue and staggered times of arrival (8-4 or 9-5) take care of it. From the histologists' viewpoint the 4 10s were great because they could choose a Friday or Monday to take off and often they could take 4 day weekends, switching off weekends. (One or two part-timers cover any necessary weekend work, with full-timers available as needed.) It was great for morale and there was a nice coffee-and-doughnut kinship among the 7am crew (management/administration has always worked 5 8's... or 5 10s as it often turns into!). From the management perspective it got too difficult to work at half-staff for 2 days of the week. For a long time the part-timers filled in on those days, but as a small company, most of our histologists are senior and are very involved with project management... not having them in to supervise the part-time techs and communicate with clients pushed us over the edge. Plus, with increasing volumes, scheduling the work/specimen flow got too complex. Another note: on the 4-day system it is much more noticeable and hard to recover from someone taking a sick or personal day. In a larger company some of these issues may not exist... but there's my $0.04.

Hello to HistoLand.

Dear histonet contributors,

I would greatly appreciate any advice about antibodies that work well with
ferret tissue (and any related processing tips).  We are particularly interested
in antibodies to markers for fibroblasts, myofibroblasts, endothelial, smooth
muscle and inflammatory cells, as well as extracellular matrix.  Thanks very
much,

Hi, 

Does any know from where to buy ready-to-use ethanol (100%, 95%, 70%)
molecular biology grade and RNase-free, compatible for Laser Capture
microdissection staining protocol?. Thank you very much.

Sonya,

You can try PLP immersion fixation followed by sucrose cryoprotection, but 
the publication I read (reference was in a Histonet message yesterday) did 
a fixation study with PLP and other fixatives.  They had little success 
with the NK1.1 (P136) antibody following immersion fixation with all 
fixatives, before snap freezing or after fresh tissue frozen sections were 
cut.  They had nice staining following PERFUSION (with PLP) of the 
mouse.  After perfusion, and once the tissues are dissected out, then 
immersion into this fixative should ensure complete fixation.  You may want 
to do final fixation in PLP  overnight, some do it for 5 - 6 hours longer 
here, then do the 30% sucrose cryoprotection at 4C. Just remove the tissue 
from fixative and go to the sucrose solution as Bruce suggested.  Small 
fixed tissues often float on top of the sucrose solution.  A general rule 
of thumb the that cryoprotection is done, tissues sink to the bottom of the 
container.

Some people use a sucrose gradient, often seen in the literature, but we 
have never found that necessary.  We blot off the excess sucrose solution 
before embedding in OCT.

Hopefully you have access to a perfusion methods IF your immersion fails.

I am looking for cryomold adapters and I hope someone can help.  The
ones we are using have a round center and are a white, hard plastic.  I
can find adapters that have a square center but that isn't what we want.
I have tried the usual vendors but was hoping someone could help me.
Thanks in advance for  your help.

Hi Everyone,

We are interested in hearing about different procedures for recovering
small cytology aspirates (any fluid really!) ... and making a cell block
from them using some type of coagulative process/fluid/etc. ... so that
virtually all of the cells are retained!

 

There may be some commercial products available ... would like to hear
about those as well.!!

 

Thanks!!!!

I have tried it.
  Cons: If yu don't have a flow of specimens in 4 days equivalent to the flow on 5 days, the personnel will be idling some time each day. If specimens or workload is available everybody will have work to do.
  Pros: it is fantastic having 3 days off weekly. Everybody likes that!
