||"Single-cell transcriptome analyses, which can be
achieved through the use of various platforms, such as
microarrays, massively parallel sequencers and bead arrays
[12-17], are able to identify cell-type markers and/or rare
cell types in tissues."
||"These platforms [mentined in Method above] require nanogram
quantities of DNA as the starting material. However, a
typical single cell has approximately 10 pg of total RNA
and often contains only 0.1 pg of polyadenylated RNA,
hence, to obtain the amount of DNA starting material that
is required by these platforms, it is necessary to perform
whole-transcript amplification (WTA)."
