The active RNAi intermediate is the small interfering RNA (siRNA), a discrete nucleic acid duplex that can be generated by several methods and used to directly silence gene expression.
Dendrograms of evolutionary relations of the 5'-NCS were produced by several methods, including: cluster analysis using pairwise C LZ values; evolutionary trees of DIALIGN sequence alignments; and cladistic analysis of conserved blocks.
The specificity of the staining was ascertained by several methods, including the use of PBS or isotypic nonspecific antibodies in lieu of the specific anti-PKC α antibody.
The heads were fastened by several methods, some still in use.
The tumoral CXCR4 expression has been evaluated by several methods, one of which being commonly used is the standard immunohistochemical staining.
