Kinetic studies on depurination and detritylation of CPG-bound intermediates during oligonucleotide synthesis.

Fully protected CPG-immobilized monomer, dimer and trimer oligonucleotides were used to study depurination during the chemical synthesis of oligonucleotides. Disappearance of the oligonucleotide during acid exposure time relative to an internal thymidine standard not subject to depurination was monitored by reverse phase HPLC analysis. Depurination half-times obtained for dichloroacetic acid (D...

Acid binding and detritylation during oligonucleotide synthesis.

Under the conditions normally used for detritylation in oligonucleotide synthesis, the haloacetic acid binds strongly to the oligonucleotide. Acetonitrile also forms a complex with the deblocking acid, in competition with the oligonucleotide, and drastically slows detritylation. Incomplete removal of acetonitrile during the deblock step may slow the kinetics enough to result in incomplete detri...

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Acyl-bound Intermediates in Fatty Acid Synthesis.

This over-all equation is thought to consist of the repetition of a series of reactions, each series being initiated by the condensation of malonyl coenzyme A with an unsubstituted straight chain acyl compound to form ,&ketoacyl-S-enzyme (5, 8). A series is then presumably concluded by reactions in which the P-ketoacyl compound is reduced and dehydrated to form an acyl compound 2 carbon atoms l...

postnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)

1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
