Applications
Used as a pharmaceutical intermediate to reduce toxicity and as an enzyme substrate in diagnostic reagents. Salmon-gal is used in conjunction with IPTG for detection of β-galactosidase activity in bacterial colonies in a colometric assay to detect recombinants (white) from the non-recombinants (SALMON). In conjunction with X-glu, salmon-gal is useful for simultaneous detection of GUS and Lac activities on the same plate.

Solubility
Insoluble in water. Soluble in DMSO and DMFO, methanol.

Notes
Moisture sensitive. Store away from water/moisture, heat and oxidizing agents. Keep the container tightly closed and place it in a cool, dry and well ventilated condition. Store under inert gas.
