A novel TLC spectrofluorometric method for identification and determination of selenium in different food samples of animal and vegetable origin has been proposed [30]. The procedure involves the digestion of food sample (1 to 5 g) in the presence of cone. HNO3 (5 ml), 70% HCIO4 (10 ml), and FIjO (10 ml) in a 250-ml Kjeldahl flask reduction of Se(VI) into Se(IV) complexation of the isolated selenium with 23-diaminonaphthene (DAN) extraction of the resultant Se—DAN complex with cyclohexane and spectrofluorometric determination followed by confirmation of the presence of Se in the sample by TLC using thin layers of MN-300 cellulose powder.

SFC-based methods still need to show their potential, in spite of past great promise. pSFC-APCI-MS is a powerful method for identification of polymer additives, provided that a library of mass spectra of polymer additives using this technique is available. SFC-MS appears less performing than originally announced nevertheless, SFE-SFC-EIMS is an interesting niche approach to additive analysis. On the other hand, we notice the lack of real breakthrough in SFE-SFC-FTIR.

It should be emphasized that the nature of all presented protocols is very general and, thus, their application for a comprehensive characterization of your favorite multiprotein complex (YFMPC) in yeast might require only minor modifications. The logical sequence of all required steps is schematically shown in Fig. 2.1. The initial large-scale Ni affinity isolation of eIF3 followed by mass spectrometry (MS) of its subunit composition has already been described (Asano et al, 2002), and methods for identification of protein-protein interactions such as yeast two-hybrid (Y2H) and in vitro glutathione-S-transferase (GST) pull-down analysis are presented in volume 429. This chapter focuses on a description of the small-scale one-step in vivo affinity purification techniques that were used to determine the effects of deletions and...

Szabo et al (39) described method for identification and determination of methimazole by conversion into its coloured 1 1 Cu+ complex which has an absorption max. at 614 nm. The complex is not stable, but on treatment with HC1, a 2 1 methimazole CuCl complex is precipitated as white crystals. 

Immunohistochemistry is a powerful method for identification of proteins in cells and tissues, but control procedures are necessary. The specificity of the results depends on two independent criteria the specificity of the antibody and of the method used (Burry 2000). The antibody specificity is best determined by immu-noblot and/or immunoprecipitation. The specificity of the method is best determined by both a negative control, replacing the primary antibody with the corresponding IgG (must be the same species as primary antibody at the same concentration), and a positive control, testing the primary antibody with tissues known to contain the antigen. 

As in many countries where maximum levels are set for the use of intense sweeteners in foods, analytical methods for identification and quantitative determination are required. Although a wide variety of methods is described, the European Standards for sweetener analysis deserve special attention. They were based on the most widely used analytical methods available and also demonstrated applicability and reliability in collaborative studies in several laboratories.
