A new promising "capping agent" (x) was synthesized by use of a lipophilic amino protecting group and an activatable pyrophosphate protecting group. This agent reacted homogeneously with 5;rnucleotides in the presence of AgN03 to afford the cap structures (m7G pppNu).

β¦ Synopsis
A relatively simple and inexpensive method has been developed for the preparation of highly purified rabbit reticulocyte globin mRNA. After phenol extraction, polysomal RNA was chromatographed on Sigmacell type 38 cellulose and Sepharose 4B. The resulting mRNA preparation has a purity in excess of 90%. No selective loss of either alpha or beta globin mRNA is observed.

Pure arachidonic acid ( L ) and docosahexanoic acid ( 2 ) are available by a two-step purification method from commercial 50% acids with high efficiency. Arachidonic acid ( J\_ ) is an important starting material for biochemical studies and for the synthesis of eicosanoids such as leukotrienes and
We describe a straightforward and simple method for obtaining pure and active preparations of type 1 ribosome inactivating proteins (RIPs). The very high isoelectric point values, characteristic of these proteins, allow this purification in a single chromatographic step.
A method is described for the rapid purification of acid deoxyribonucleases. It primarily involves chromatography of the enzyme-containing preparation through a DNA-ECTEOLA-cellulose column. This column retains the DNAse activity but not the inactive protein, and consequently, high degrees of purifi
## Abstract The reaction of one g.βatom sulphur, six g.βatoms bromine and an excess of water has been studied. The reaction takes place in at least two steps, the first being the formation of sulphur monoβbromide, the second the reaction of this compound with bromine and water. The reaction results
