XJb(DE3) Autolysis W/1 Glycerol Stock & 1 Ml 500X L-Arabinose

Versatile: Fully compatible with a wide range of buffers for protein purification and other physical methods of lysis.Autolysis: XJb lysis efficiency is 10-20 % lower than XJa. The E. It lacks Lon and OmpT proteases, leading to higher protein yields.Shipping Weight: 0.125 lbsShipping Dimensions: 2.00 x 2.00 x 2.00Research or further manufacturing use only, not for For optimal lysis, more care needs to be taken when selecting the lysis buffer. Cell Growth: A very robust strain, reaching higher OD€s than E. Mild expression of a chromosomally encoded bacteriophage λ R gene, encoding the λ lysozyme, also known as λ endolysin, is induced during growth. Fast: 80 - 90% of E.coli are lysed in only 10 minutes after harvesting.DE3 Lysogen: Encodes the T7 polymerase for expressing recombinant proteins under the control of the T7 promoter. coli K-strains. However, even very low concentrations of detergent may improve lysis significantly. They are also applicable for nucleic acid purification, and available with a DE3 lysogen encoding the T7 polymerase for expressing recombinant proteins driven by the T7 promoter. Cells are harvested intact while the peptidoglycan layer of the cell walls has been protected from digestion by the cytoplasmic membrane. Additionally, it does not require use of any potentially interfering components such as detergents, commonly found in various lytic buffers. The membrane is, however, amenable to disruption by a brief physico-chemical stress such as a freeze-thaw cycle after harvesting the cells. Genotype: F- ompT hsdSB(rB - mB -) gal dcm ΔaraB::λR, cat (CmR), λ(DE3)Processing Time: 10 minutes Product Storage: -70°C to -80°C Protein Expression: XJb is ideal for recombinant protein expression. coli cells. It can be applied to any number of samples without increasing processing time and labor (unlike sonication or French-press), is reliable and repeatable (unlike lysozyme treatment), and finally, is fully compatible with a wide range of buffers. DNA Extraction: XJb is not optimal for DNA extraction.DNA Stability: This strain is RecA positive. coli XJ autolysing strains from Zymo Research were engineered to address this problem. The XJ Autolysis method is highly efficient and takes only minutes (unlike traditional multiple freeze-thaw cycles). While there are many cell lysis methods available to scientists, unfortunately none of these methods combine all the ideal features for simple, efficient, economical, and gentle lysis of E.
