Summary electrophoretic data base on human embryonic kidney cell strain 8514

To properly plan the electrophoresis equipment verification test (EEVT) and continuous flow electrophoresis system (CFES) experiments with human embryonic kidney cells, first a candidate cell lot had to be chosen on the basis of electrophoretic heterogeneity, growth potential, cytogenetics, and urokinase production. Cell lot 8514 from MA Bioproducts, Inc. was chosen for this purpose, and several essential analytical electrophoresis experiments were performed to test its final suitability for these experiments.

Simultaneous measurement of multiple radiation-induced protein expression profiles using the Luminex(TM) system

Space flight results in the exposure of astronauts to a mixed field of radiation composed of energetic particles of varying energies, and biological indicators of space radiation exposure provides a better understanding of the associated long-term health risks. Current methods of biodosimetry have employed the use of cytogenetic analysis for biodosimetry, and more recently the advent of technological progression has led to advanced research in the use of genomic and proteomic expression profiling to simultaneously assess biomarkers of radiation exposure. We describe here the technical advantages of the Luminex(TM) 100 system relative to traditional methods and its potential as a tool to simultaneously profile multiple proteins induced by ionizing radiation. The development of such a bioassay would provide more relevant post-translational dynamics of stress response and will impart important implications in the advancement of space and other radiation contact monitoring. c2004 COSPAR.
