摘要:Compounds which are capable of generating acid on photolysis are disclosed, and the uses of these compounds, especially for deprotecting the termini of nucleic acid molecules or peptides during synthesis of arrays. The compounds described herein may be employed in the detritylation of 5′-O-dimethoxytrityl (DMT) protected nucleotides by photolysing the compounds to generate an acid capable of removing the DMT group allowing oligonucleotide arrays to be synthesised using readily available 5′-O-DMT-nucleoside-3′-O-phosphoramidite monomers conventionally used in solid phase nucleic acid synthesis. A method of avoiding the effects of stray light in projection lithography techniques is also disclosed.

摘要:A process for preparing bromine-containing dyes labelled with gamma-emitting isotopes of bromine, and the product thereof which is useful as an imaging agent for the hepato-biliary system, particularly in dynamic imaging methods. The dyes prepared are from the class of triarylmethane dyes, and also from the phthalein subclass of the class of xanthene dyes, and the labelling thereof is effected with 76Br, 77Br or 82Br. The process for preparing these dyes involves reacting the non-brominated dye precursor with either 76Br2, 77Br2 or 82Br2. This is a substitution type of reaction in which a ring hydrogen is substituted by either 76Br, 77Br or 82Br.
