Product Description
Make blue-white screening faster and clearer. This Zymo Research X-GAL solution comes sterile and ready to use, so you can add it straight to agar plates without weighing powder or dissolving it in DMF, and get vivid blue colonies that stand out from the background.
This listing is for catalog number X1001-25: 5-bromo-4-chloro-3-indolyl β-D-galactopyranoside (X-GAL), 5 x 5 mL. The 2% solution is formulated to reduce false positives during blue-white selection, helping you pick recombinant clones with greater confidence. Spread or mix it into plates for lacZ-based screening of cloning reactions. Available as a single 5 ml vial or a pack of five 5 ml vials.
