Purity of Synthetic Peptide Preparations

Criteria for Purity of Chlorophyll Preparations*

It is inevitable that the separation in pure state of substances which cannot be purified by recrystallization or by other common methods should prove difficult, and that criteria of purity should be correspondingly less convincing. The primary purpose of this paper is to establish satisfactory criteria for several chlorophyll preparations, especially with reference to their absorption of light...

Purity of synthetic cannabinoids sold online for recreational use.

The recreational use of synthetic cannabinoids has recently increased. This increase is due, in part, to the recent availability of inexpensive compound sold legally online in bulk. In particular, JWH-018 (1-pentyl-3-(1-naphthoyl)indole) and JWH-073 (1-butyl-3-(1-naphthoyl)indole) have been found in herbal blends marketed as alternatives to cannabis. Although these particular compounds have rec...

Peptide-based synthetic vaccines

Classically all vaccines were produced using live or attenuated microorganisms or parts of them. However, the use of whole organisms, their components or the biological process for vaccine production has several weaknesses. The presence of immunologically redundant biological components or biological impurities in such vaccines might cause major problems. All the disadvantageous of traditional ...

[Synthetic peptide vaccines].

This review considers the stages of the development of synthetic peptide vaccines against infectious agents, novel approaches and technologies employed in this process, including bioinformatics, genomics, proteomics, large-scale peptide synthesis, high-throughput screening methods, the use of transgenic animals for modelling human infections. An important role for the development and selection ...
