The use of tert-butylphenoxyacetyl for N-protection of nucleoside bases during oligonucleotide synthesis facilitates its removal under mild conditions. This protecting group reduces depurination of deoxyadenosine residues, and minimizes premature desilylation resulting in chain degradation during post-synthesis workup of synthetic RNA.

A direct fluorometric high-performance liquid chromatography (HPLC) method was developed and validated for the analysis of ibuprofen enantiomers in mouse plasma (100 μl) and tissues (brain, liver, kidneys) using liquid-liquid extraction and 4-tertbutylphenoxyacetic acid as an internal standard. Separation of enantiomers

Chemokines are essential mediators of normal leukocyte trafficking as well as of leukocyte recruitment during inflammation. We describe here a novel non-ELR CXC chemokine identified through sequence analysis of cDNAs derived from cytokine-activated primary human astrocytes. This novel chemokine, referred
