Source Of Error

Plastic consumables, used universally in bioscience laboratories, are presumed inert with respect to bioassay outcomes. However, it is clear that many pipette tips, microfuge tubes, and other plastic disposables leach bioactive compounds into assay solutions, profoundly affecting data and experimental interpretation. In this paper we discuss the nature and sources of leachates and review several examples of compromised bioassay data that speak to the probable widespread nature of this largely unrecognised source of error. Strategies for minimizing leachate interferences are discussed.

Ribosomes are ribonucleoprotein particles necessary for processing the genetic information of mRNA into proteins. Analogy in composition and function of ribosomes from diverse species, established by biochemical and biological assays, implies their structural similarity. Direct evidence obtained by electron microscopy seems to be of increasing relevance in understanding the structure of ribosomes and the mechanism of their role in protein synthesis.The extent of the structural homology between prokaryotic and eukaryotic ribosomes has been studied on ribosomes of Escherichia coli (E.c.) and Artemia salina (A.s.). Despite the established differences in size and in the amount and proportion of ribosomal proteins and RNAs both types of ribosomes show an overall similarity. The monosomes (stained with 0.5% aqueous uranyl acetate and deposited on a fine carbon support) appear in the electron micrographs as round particles with a diameter of approximately 225Å for the 70S E.c. (Fig. 1) and 260Å for the 80S A.s. monosome (Fig. 2).
