No, the kit specifies that the *width* of the dot is used to determine
the concentration, not the colour. If it had been colour I would have
assumed amido black too. It also claims to be an absolute scale, with no
standards required - the kit comes with a scaler to size the dots on and
get the concentration from.
The protocol is dilute, spot, fix, develop. Big surprise, there's no
composition given in the on-line documentation for the dilution,
fixative or developing buffers.
