Descrizione

CAS: 138182-21-5 | C14H16ClNO6 | 329.73 g/mol

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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
