These monodispersed dendrimers possess patterns reminiscent of the branching of trees. Asymmetrical Doublers can be synthesized at the time of synthesis. These Dendrimers (1,2) offer the following advantages:

  • Increase in proportion to the number of 5' end when label using γ-32P-ATP and polynucleotide kinase
  • Increased fluorescent signal at 5' end if spacers are incorporated between the labels and the ends of the branches.
  • Dendrimeric bearing primers are resistant to degradation by T7 Gene 6 Exonuclease making it easy to convert the double-stranded product of PCR to a single-stranded probe with multiple labels. 
  • Enhanced stability and useful as building blocks for 'bottom up' nano-assembly.
