Product Description
Keep an autolysing E. coli strain on hand for gentle, repeatable lysis. This Zymo Research XJb autolysis glycerol stock provides cells engineered to open after one freeze-thaw cycle, avoiding sonication, French presses and potentially interfering detergents. It is ideal for labs that prefer to grow their own cells.
This listing is for catalog number T5041: XJb Autolysis Glycerol Stock, 1 Tube. During growth, cells mildly express a chromosomal bacteriophage lambda R gene encoding lambda endolysin. The cytoplasmic membrane shields the cell wall until harvest, after which a single brief freeze-thaw cycle triggers efficient lysis. The strain is also well suited to nucleic acid purification, and a DE3 version is offered separately for T7-driven protein expression. Supplied as a single glycerol stock tube for establishing your own cultures and competent cell preparations. Add it to your LIGHT LABS order and keep your bench stocked.
Key Features
- Built-in autolysis – a chromosomal bacteriophage lambda R gene (lambda endolysin) is mildly expressed during growth.
- One freeze-thaw lysis – a single brief freeze-thaw cycle disrupts the membrane and releases contents in minutes.
- Scales easily – process any number of samples without added time or labor, unlike sonication or French press.
- Detergent-free – compatible with a wide range of buffers and avoids potentially interfering lytic additives.
- Nucleic acid prep compatible – gentle lysis also supports DNA and RNA purification.
