Description General description HLAM-AβIδ1MεLVproSTγ-13CH3 kit has 13CH3 isotopomer precursors and contains protocol instructions for creation of isotopically-labeled proteins. Application For detection of long-range nOes or for the NMR study of large proteins HLAM-AβIδ1MεLVproSTγ-13CH3 is an optimized kit used to produce proteins with 13CH3 isotopomer on methyl groups of alanine, isoleucine, methionine, leucine and threonine residues. This kit has been tested with protein isotopic labeling in E. coli. It can be used to study large molecular system and complex protein structure in NMR spectroscopy along with other spectroscopic approaches. The sensitivity of the isotopomer can be enhanced by three-fold multiplicity. This kit can also be used to simplify crowded spectra to provide specific probes of dynamic and structural studies in solid state NMR spectroscopy.
