[Histonet] decalcification of articular cartilage

You could always get formical which fixes and decals at the same time.  This would eliminate the waiting for fixation.  Although I do usually let it fix in straight formalin overnight first.

We do a lot of IHC staining on bone and cartilage samples and we use 10% formic acid for decalcification for immunohistochemistry.  I'm afraid you may not be able to turnaround this in a week.  The tissue needs to be adequately fixed prior to decalcification, and properly decaled.  I would trim the tissue to about 4 mm thick if you can on a saw you might be able to turn this around in  your time frame, but I have learned from experience if you rush decalcification you have a greater chance of running into problems.

Dear Members,

We're planning to study sheep knee articular cartilage with histochemistry and immunohistchemistry. Proximal parts of the tibia bones fixing in formaldehyde at the moment. We need an effective, quick and cartilage tissue protective decalcification method. We'll perform only light microscopic examination in this study and we have to complete the study within one week. In these circumstances what are your advices?
Thanks in advance.
