Lipases/esterases can be used as versatile tools in hydrolytic reactions, esterifications and transesterification reactions in industrial and food applications. The lipase from the yeast Y. lipolytica has a temperature optimum in the 30 - 40 °C range and pH optimum between pH 7 and 8.

Isoamylase (also known as debranching enzyme, systemic name glycogen α-1,6-glucanohydrolase; EC 3.2.1.68) is the enzyme that cleaves α-1,6-glucosidic branch linkages in carbohydrates, namely amylopectin or glycogen.

Lipase 44 recombinantly expressed in E. coli comes in a spray-dried formulation. It has its pH optimum at 7-10 and temp. optimum at 50°C. Lipases belong to the family of esterases and naturally act on triglycerides at lipid-water interfaces catalyzing hydrolytic reactions, esterifications and transesterification reactions in industrial and food applications. Lipase 44 was shown to hydrolyze p-Nitrophenyl esters of butyrate (70 % activity compared to octanoate), octanoate (100 %), laurate (88 %), palmitate (6 %) and stearate (2 %).

Supplied as lyophilisate containing 1% w/w X-Shining™ Luciferase. The improved, thermostable X-Shining™ Luciferase is suitable for any luciferin-luciferase-based assay using D-luciferin (dLuc) or synthetic pro-luciferins (caged luciferins). Examples of its typical applications include ATP tests in hygiene monitoring, ATP tests in drug screenings and bacteria identification in microbial assays. The termostable luciferase X-Shining™ has been optimised by genetic engineering for strongly increased thermostability and storage stability. In temperature stress tests, the enzyme survives temperatures of 60°C for over an hour, whereas a wild type luciferase from firefly is inactivated after only a few minutes. The extraordinary stability makes it user-friendly and eliminates some of the main disadvantages and limitations of the commonly used wild type luciferase. X-Shining™ Luciferase is supplied as a lyophilisate (1% w/w X-Shining™ Luciferase) or as aqueous solution with glycerol (L-8093), and it may be stored for months at room temperature without significant loss of function. Find out more about our innovative X-Shining range here X-Shining | Innovation | Cymit Quimica Carbosynth.
