RE: [Histonet] hyaluronidase digestion for aggrecan staining

From:"Hermina Borgerink"


Many years ago when I was still routinely doing immuno staining on bone
and articular cartilage, this is the formula for hyaluronidase digestion
I used:


0.1mg/ml bovine testicular hyaluronidase

0.05M Tris-HCl pH 7.6
0.15M NaCl
0.1% CaCl2
deionized water

Incubate sections at room temperature for 30 minutes prior to primary
antibody incubation.

Hello All


We have been working on aggrecan immunostain on articular cartiage and
wanted to perform a hyaluronidase digestion prior.  I have searched
extensively and have come up with few methods, none of which is
Does anyone out there have a method that includes the molarity of the
buffer, the pH of the buffer and the amount of hyaluronidase used and
the length of time and temp, etc..  Any advice would be helpful.


Thanks in advance
