the source mainly include： chemically synthesized enzymatically synthesized plasmid based siRNA expression cassette new method are also accepted。 The type of control include Positive, negative, mismatch and so on mRNA level or Protein level or others PubMed id The range of sequence: 234,253(start position, end position) The seqpostype defined the type of sequence. [Fs|Fa]\|[0-9]+-[0-9]+ Fs from the start Fa from ATG For example: Fs|45-74 Fa|34-53 to easily describe the position of modified base in the antisense sequence, we use the regualar expression to difine the type of modifiedpositon. (([1-9][0-9]*,)*[1-9][0-9]*-)*([1-9][0-9]*,)*[1-9][0-9]* example is : 1-20; 1,3,4-7-11,13 1,2,19,20 the type of strand，sense(+) or antisense(-) strand。 The SeriesID, sometimes one sequence could have more than one experimental results, so the seriesID can discriminate them.
