5-Acetamidofluorescein di-(β-D-galactopyranoside) ≥95%

Dodavatel: Apollo Scientific

Popis: 5-Acetamidofluorescein di-(β-D-galactopyranoside) ≥95%

Fluorescein di-b-D-galactopyranoside (FDG) ≥95%

Katalogové číslo: (AATB14001)

Dodavatel: AAT BIOQUEST

Popis: Although chromogenic assays of beta-galactosidase activity (i.e. X-Gal) are still widely used, the recent advance in fluorescence instrumentation has made fluorogenic substrates (such as FDG and MUG) be several orders of magnitude more sensitive. FDG is considered to be one of the most sensitive fluorogenic substrates available for detecting beta-galactosidase.

X-Gal ≥98.0%

Katalogové číslo: (437132J)

Dodavatel: VWR Chemicals

Popis: X-Gal is a chromogenic substrate for ß-Galactosidase that forms an intense blue precipitate. Used in conjunction with IPTG in a colorimetric assay, X-Gal allows differentiation of recombinants from non recombinants in cloning experiments with vectors containing the lacZ gene. It is also used in microbiology to detect microorganisms which have ß-Galactosidase activity.
