Background and Aims: DNA cloning, sub-cloning and site directed mutagenesis are the most common strategies in nearly all projects of recombinant protein production. The classical method of restriction site cloning is unsatisfactory due to the need for supply of restriction enzymes and the inefficiency of the digestion reaction. Many new methods, including recombinatorial cloning and ligation in...
Direct cloning of PCR fragments by TA cloning or blunt end ligation are two simple methods which would greatly benefit high-throughput (HTP) cloning constructions if the efficiency can be improved. In this study, we have developed a ribosomal binding site (RBS) switching strategy for direct cloning of PCR fragments. RBS is an A/G rich region upstream of the translational start codon and is esse...
background:the premature termination of high producer clones, which will be killed due to cell proliferation and proteins production antagonism, is one of the basic drawback in recombinant proteins technology. furtheremore, it is supposed some toxic proteins like interferon which we intended to clone and express, inhibit host cells’ proliferation. so, it is necessary to tightly control ifn-γ pr...
Re c e n t a dva n c e s in m o l e c u l a r b io l og y t ech n i q u e s p er m i t scientists to identify genetic contributions to alcoholism. Two main types of technology are commonly used to identify genes that cause or predispose a person to a disease: positional cloning techniques and candidate gene techniques. Positional cloning techniques allow disease genes to be identified based sol...
Multiple Sclerosis (MS) is a chronic neurological disease of the central nervous system (CNS), characterised by a cellular immune response in early stages and demyelination of the CNS later. Although the cause of MS is unknown, there is much evidence that points to MS as an autoimmune disease. To test the hypotheses that an Autoantigen is involved in MS, we screened a ?gt11 human foetal spinal ...
Neuropeptides are known to be important signaling molecules in several neural systems of the pond snail Lymnaea stagnalis. Although the functions of these peptides have been studied in many neurons, the nature of the postsynaptic signal transduction is mainly unknown. The cloning and characterization of neuropeptide receptors in Lymnaea thus would be very valuable in further elucidating peptide...
