Simple immunofluorescent method for identification of blood group in human tissues.
An immunofluorescent detection of IgM for visualization of isohemagglutinin absorption in human tissue sections was used for the identification of the blood group of the AB0 system. The method is simple and available for the most part of histological laboratories.
Abstract A study of the effect of alkane gases on the atomic fluorescence signals of some refractory elements has been made, with a low power inductively coupled plasma (ICP) as the atomiser, and a high power ICP as the source. Detection limits are, for some elements, inferior to those obtainable by ICP-Atomic Emission Spectrometry (ICP-AES). However, an improvement by a factor of two has been obtained for tungsten by using ethanolic solutions instead of adding traces of hydrocarbon gases.
