In conclusion, synthesis of labeled derivatives of PhTX-56 provides important tools for future studies of the pore-forming region of AMPA receptors.
PhTX-56 and its labeled derivatives are promising tools for structure function studies of the ion channel of the AMPA receptor.
As described in this report, de novo chemical synthesis has enabled the preparation of fluorescently labeled derivatives of -saxitoxin, STX-Cy5, and STX-DCDHF, which display reversible binding to Na(V s in live cells.
Although the synthesis of peptides labeled with stable isotopes is relatively simple, there are several factors limiting application of these standards in proteomic research: cost of labeled derivatives of amino acids, time needed to obtain labeled peptide and problems with quantification of the standard.
Figure 3 shows results of biodistribution experiments performed at 1, 6, and 24 h after injection of 111In labeled derivatives BN1, BN4, BN7, and BN8.
This has required the preparation of related H labelled derivatives.
Henry and colleagues [ 44] labeled derivatives of the endoderm in the polyplacophoran species Chaetopleura apiculata via injected fluorescent markers in cell lineage experiments.
For fluorescence-activated cell sorting (FACS), BY4741 was used with mCherry labelled derivatives of pHLUM, pHLM- GPDpr-mCherry, and pUM- GPDpr-mCherry (Table 1).
In this study, we used fluorescently labeled derivatives of PGPC and POVPC to measure lipid uptake into cultured RAW 264.7 macrophages and identify their primary protein targets.
This synthetic approach to specifically labeled derivatives offers significant advantages over the established intein method,[ 14c] which is largely limited to the natural amino acids.
