Decal formula question

From:Mass Histology Service

Hi everyone,

Here's two questions from a client in which I couldn't answer.  Can anyone
help me with them?

1)  Why is the formic acid-sodium citrate method stored in two stock
solutions and mixed just before use?

2)  Once mixed, how long is it good for?  Hours, days or weeks?
