XL-1 Blue Competent Cells for routine cloning allow blue-white color screening, single-strand rescue of phagemid DNA, and preparation of high-quality plasmid DNA. Derivatives enable higher transformation efficiency, transformation of methylated DNA, choice of …

XL1-Blue cells are endonuclease (endA) deficient, which greatly improves the quality of miniprep DNA, and are recombination (recA) deficient, improving insert stability. The hsdR mutation prevents the cleavage of cloned DNA by the EcoK endonuclease system. The lacIqZ∆M15 gene on the F ́ episome allows blue-white color screening. 1.

The XL1-Blue strain allows blue-white color screening for recombinant plasmids and is an excellent host strain for routine cloning applications using plasmid or lambda vectors. The XL1-Blue cells are endonuclease (endA) deficient, which greatly improves the quality of miniprep DNA, and are recombination (recA) deficient, improving insert stability.

Stratagene has developed a method* to produce electroporation-competent cells that have the highest transformation efficiencies—greater than 1 × 1010 transformants/μg of DNA. These electroporation-ready cells need only be thawed, mixed with DNA, and electroporated.

アジレント (旧ストラタジーン)の XL1-Blue 株は、プラスミドベクターおよびラムダファージベクターの両ベクターの増幅に利用できる菌株で、高品質のプラスミドDNAの回収に適した EndA (-) 表現型です。 また、青/白スクリーニングやファージミドDNAの一本鎖回収などにも適しています。 F' エピソームには抗生物質耐性があり、最小培地プレートによるセレクションをす …

XL1 and XL2-Blue Competent Cells are versatile for routine cloning and allow blue-white color screening for high efficiency cloning of methylated DNA. Designed to provide a host for optimal propagation of both plasmid and lambda phage vectors

XL1-Blue is the most popular strain for blue/white screening. It is also an excellent host strain for routine cloning application using plasmid or lambda vectors. XL1-Blue cells are endonuclease (endA) deficient, which greatly improve the quality of …
