This method of direct cloning takes advantage of the unpaired adenosyl residue added to the 3' terminus of amplified DNAs by Taq and other thermostable polymerases. - [Read Cloning PCR Products into T Vectors Protocol]
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]
Novel strategy of immunizing a phosphorylated peptide or a synthetic phosphopeptide, which corresponds to the protein phosphorylated at a targeted residue. Method has been applied to the production of antibodies that can specifically recognize the other types of site-specific protein modification, such as acetylation, methylation, and proteolysis. - [Read Functional Analyses for Site-Specific Phosphorylation of a Target Protein in Cells]
PDP-Hydrazide 3-(2-pyridyldithio)propionyl hydrazide is heterobifunctional cleavable crosslinker containing a hydrazide group and pyridyl disulfide residue that react with carbohydrates and sulfhydryls, respectively.

Protocol exploits the discovery that Rnase A can efficiently cleave at single rC or rU bases embedded in double-stranded DNA. Entire plasmid vectors are amplified using long, high-fidelity PCR with riboprimers, which carry a single rC residue at their 3' end. Target DNA is amplified using similar primers, which also end in a rC residue. - [Read Ribocloning: DNA Cloning and Gene Construction Using PCR Primers Terminated with a Ribonucleotide]
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.
