Accordingly, RNP preparations were sheared by vigorously vortexing solutions for 1 min. Previous electron microscopic evaluation of RNP preparations showed that such manipulation reduces the range in particle length, resulting in a smaller mean, a smaller standard deviation of the mean, and a reduction in the amplitude of sensorgram spikes (Oglesbee et al., unpublished observation, 25).
Evaluation of the preparations was done using a fluorescent microscope (Axioskop, Zeiss) and a confocal microscope (Olympus Fluoview IX81).
However, surprisingly preclinical or clinical evaluation of such preparations is not available in the literature.
However, preclinical or clinical evaluation of such preparations is surprisingly limited in the literature [ 12– 16].
Microscopic evaluation of histological preparations may be used for investigation of endochondral ossification process in growth plates [ 17].
So far, the methods commonly used for quality evaluation of TCM preparations mainly focused on chemical ingredients.
So far, the commonly used methods for quality evaluation of TCM preparations have mainly focused on chemical ingredient analysis by various chromatographic and spectroscopic methods [3,4].
The isolation and purification of tubulin from kinetoplastids such as T. brucei [ 16] and Leishmania spp. [ 14, 17] have been carried out successfully, and evaluation of such preparations demonstrated their suitability for use in screening of drugs with selective antimitotic activity, such as dinitroaniline herbicides, oryzalin, and derivatives compounds [ 14, 18].
Although the literature is scattered with platform-specific sample preparation procedures, there is a paucity of studies reporting the systematic evaluation of sample preparation across multiple platforms.
The mathematically based information (sedimentation time, kinetics of sedimentation, etc). is essential for an exact evaluation of the preparation of the coating fluid.
