With Qbiogene's XTRA-Blue™ Plus X-Gal/IPTG Solution no DMF/DMSO is required. XTRA-Blue™ Plus is a ready-made solution containing X-Gal and IPTG that maintains its functional activity for months at 4° C. Due to its high stability XTRA-Blue™ Plus can be mixed with agar and antibiotics and poured in plates in advance. For the user this means a valuable savings in time and effort. For researchers using high throughput robotic colony pickers, the stability and intense blue coloration can improve picking efficiency.

XTRA-Blue™ Plus solution contains non-hazardous, non-toxic solvents and so is also suitable for use with cultured mammalian cells.

Storage at 4° C avoids the freeze-thaw cycles that can impair the quality of X-Gal and IPTG leading to greater reliability of results.

Another remarkable advantage of XTRA-Blue™ Plus is its efficiency as a substrate no incubation at 4° C is needed to generate a bright blue coloration for negative colonies.

Quality Control:
Each batch is tested against classical X-Gal/IPTG method, with 2 different strains expressing pUC19 (high copy plasmid) or BAC2 (low copy plasmid).

Sterility:
XTRA-Blue™ Plus is filtered through 0.22 micron membrane.
