What alternatives to epinephrine/norepinephrine could be used for contracting pigments in zebrafish?

03 August 2017 0 4K Report

I want to count pigments on AB strain zebrafish and I've been looking at literature for the same. Epinephrine appears to be the chemical of choice but Sigma Aldrich labels it as highly toxic. Combined with the stringent health and safety laws in UK universities, it is proving to be hard for me to acquire the chemical. Are there any alternatives that will contract pigment granules to facilitate counting?
