Bosma-Steiner Method:


-Uranium nitrate-mastix solution:
	Uranyl nitrate	2g
	Alcohol 100%	45 ml
	Mastix stock solution (Chroma art. 3D045)	20 ml
-Silver nitrate solution:
	Silver nitrate	0.7g
	DH20			70 ml
	Alcohol 100%	60 ml
	Mastix stock 	40 ml
-Brenzcatechin solution:
Brenzcatechin	3.5 g
DH20			70 m
-Amylase solution:
	'alpha-amylase' type VI (Sigma #A6880) 0.7 g
	DH20			70 ml

Fixation:	10% formalin

Technique:	Paraffin sections cut at 3um, or plastic at 2um.

Staining procedure:

1.	Deparaffinize and hydrate to DH20.
2.	Place slides in plastic staining jar containing amylase solution at
37 degree C, heat in oven for 1 hour.
3.	Rinse slides briefly in DH20, place slides in alcohol 95% for 1 min
and in 100% for 2 min.
4.	Place slides in uranium nitrate-mastix solution for 5-10 min.
5.	Rinse in DH20 for 1-2 min.
6.	Place slides in a plastic staining jar containing 70 ml of silver
nitrate solution and irradiate at 450 W (*80%), at 90 degree C for 6-10 min.
Allow the sections to remain in the solution for at least 20 min. until the
proper staining intensity is achieved.
7.	Rinse slides briefly in alcohol 80%, rinse in alcohol 95% for 1 min.
8.	Wash in alcohol 100%, 3x2 min.
9.	Place slides in alcohol-mastix solution for 5 min.
10.	Place slides in a plastic staining jar containing 70 ml of
brenzcatechin solution and irradiate at 450 W, at 90 degree C for 6 min.
11.	Rinse slides in DH20 for 1 min.
12.	Dehydrate, clear and mount.

Note:	Uranyl nitrate is radioactive!

Result:	Spirochete:black
		Backround:yellow or brown-yellow
