Found these in the archives.  I thought I remembered this coming up
before. 


Enjoy.

To macerate tissue away, use Biz detergent (local grocery store)- an
enzyme
detergent.  Make a 20% solution and heat bone at 80C until muscle comes,
slides off bone surfaces. The enzyme is the kicker here, eats away at
protein attachments.  It bleachs bones as well, smells better than just
boiling bones.  After Biz treatment, rinse bones well with running tap
water - let them air dry. 


It is a good idea to fix bones with NBF or 70% alcohol, then rinse well
overnight to get rid of formalin - you don't want to inactivate enzyme
in
detergent. Also, fixed bone holds together better (cartilage is removed
by
BIZ!) and if bones (or parts of same) separate, glue with Duco Cement,
Superglue, or a glue gun after total drying.  Nice way to learn bone
anatomy by putting it back together. 


This method came from Journal of Anatomy, many moons ago, 1980's - to
prepare skulls for gross specimen study.

This is for those who would like something whose odor befits its work.

I think Gayle Callis' BIZ might be better, but Gee Whiz folks, we're
talking
about Gross Anatomy here!  These are procedures that one used to be
forced
to carry out on the roof, or out in an open field, away from civilized
folk.
So, I thought I would contribute a recipe from an old, VERY reputable,
source.

"Liquid Soap". Reighard and Jennings, "Anatomy of the Cat" [Oops! Sorry
kitty!], 1935, Holt Reinhart

Soft water		2000ml ("Soft" is not a scientific term!)
Strong ammonia	150ml  (for glazed eyes, opaque NICtitating membranes
and,
of course, alkalinity)
KNO3			12g (for suppression of something? John and
Abigail?)
Hard soap (brown)	75g  (We used to save the shavings of the brown
soap
used in the local Cub Scout carving tutorials.  We liked the brown soap,
because it WAS harder than Ivory!  This soap is still available in a
double
bar with attractive white wrapping with pink printing.  You can't tell a
soap by its cover!)


Heat the mixture to boiling until homogeneous.
Immerse the bone and boil for 40 min
Pour off the liquid and renew it.
Boil another 30min or until the soft parts come away easily.
[Boil too long and the epiphyses will separate.]
The bone can be rinsed in water.
The bone can be defatted, after drying, in bnenzene/zylene.  


Cheers (it almost feels like Friday),

Hi all,

Does anyone know what solution to use to dissolve skeletal
muscle off of bone, so that the bone remains in tact.  This
is not for a histology study, but I thought that someone out
there on the histonet would know how to do this!

Thanks in advance,

Household bleach, 1 part bleach to 4 parts water.
or
Adolph's meat tenderizer is papain, don't know the concentration needed.

You can get papain form Sigma, works well at 37C. I don't know any other

details.
