CHO Lec3.2.8.1 cells have 4 independent mutations in the N and O glycosylation pathways. When cultured with alpha-glucosidase I inhibitor N-butyl-deoxynojirimycin, glycoproteins produced in CHO Lec3.2.8.1 cells are completely susceptible to Endo H digestion. Endo H cleaves chitobiose, leaving a single N-linked N-acetylglucosamine per site which is ideal for maintenance of protein solubility and special carb-protein interactions, such as between the first N-acetyl glucosamine residue and tryp. - [Read Establishment of Stable Transfectant of CHO Lec Cells Protocol]

Laboratory sample cleanup is a necessary part for analytical preparation analysis. The removal of Contaminants such as proteins, cell debris and other materials is an important step. Typically this has been done by using Acetonitrile and then Centrifugation to pellet the debris leaving the clean supernant. After this process supernatant can be used for further analysis by HPLC, GC, MS and other analysis tandem methods. HTS Labs. - [Read Protein Precipitation Microplate]

DNA Ligation Protocol

The DNA Ligation protocol described here contains the steps required to join together using ligase enzyme both plasmid DNA and insert DNA fragments in order to create a new plasmid. This new ligated plasmid can be transformed after into competent bacteria to produce DNA for mini, midi or maxi-prep isolation.
