Iron staining
« on: June 12, 2014, 12:08:53 PM »
Hello,

We have been using Potassium Hexacyanoferrate (II) Trihydrate for our iron staining, and we recently found out that this product has expired a year ago in our lab. Our positive control remained positive for the last batch of stainings done, but can we trust the results of the test slides? I wonder how stable this product is long after its expiration date -- will it be a cause for loss of efficiency in staining and therefore resulting to weaker to negative stain?

Thanks in advance for your thoughts.

Potassium Hexacyanoferrate (II) Trihydrate might be oxidized.
