Alkaline lysis is a method used in molecular biology to break cells open to isolate plasmid DNA or other cell components such as protein s. Bacteria containing the plasmid of interest is first grown, then lysed with a strong alkaline buffer consisting of a detergent sodium dodecyl sulfate SDS and a strong base sodium hydroxide . The detergent breaks the membrane s phospholipid bilayer and the alkali denatures proteins involved in maintaining the structure of the cell membrane. Through a series of steps involving agitation, precipitation, centrifugation, and the removal of supernatant , cellular debris is removed and the plasmid is isolated and purified. The protocol may vary slightly from lab to lab. Also, alkaline lysis is sometimes used to extract plant genetic material. The plant cells are subjected to a strongly alkaline solution containing a detergent usually a zwitterionic or nonionic detergent such as polysorbate 20 Tween 20 , and the mixture is incubated at high temperature. This method is not used as often due to the sodium hydroxide s tendency to damage genetic material, reducing DNA fragment size.

The euglobulin lysis time ELT is a test that measures overall fibrinolysis . The test is performed by mixing citrated platelet poor Blood plasma plasma with acid in a glass test tube. This acidification causes the precipitation of certain clotting factors in a complex called the euglobulin fraction . The euglobulin fraction contains the important fibrinolytic factors fibrinogen , PAI 1 , tPA , plasminogen , and to a lesser extent alpha 2 antiplasmin . The euglobulin fraction also contains factor VIII . After precipitation, the euglobulin fraction is resuspended in a borate solution. Clotting is then activated by the addition of calcium chloride at 37 C. Historically, subsequent amount of fibrinolysis was determined by eye, by observing the clot within the test tube at ten minute intervals until complete lysis had occurred. ref cite paper first E. last Kowalski author E.
