==General Notes==
*'''Stock Oligos''': reconstituted (50uM for non-biotinylated oligos, 200uM for biotinylated) oligos in wells or tubes
*'''Pre-working Stocks''': mixtures of 10uM of each oligo needed for a "class" of oligos (ex. core, barrel, lid1, lid2); for non-biot oligos, this requires 10uL of each of the necessary stock oligos, for biot-oligos, this requires 2.5uL of stock oligos + 7.5uL dH2O
*'''Working Stocks''': mixtures of however-many-oligos-are-in-each-class uL (ex. if there are 94 oligos in the core class of 3.2's design, use 94uL of the core pre-working stock), diluted to a total of 200uL of solution (each individual oligo will be at 250nM)

General Notes

  • Stock Oligos: reconstituted (50uM for non-biotinylated oligos, 200uM for biotinylated) oligos in wells or tubes
  • Pre-working Stocks: mixtures of 10uM of each oligo needed for a "class" of oligos (ex. core, barrel, lid1, lid2); for non-biot oligos, this requires 10uL of each of the necessary stock oligos, for biot-oligos, this requires 2.5uL of stock oligos + 7.5uL dH2O
  • Working Stocks: mixtures of however-many-oligos-are-in-each-class uL (ex. if there are 94 oligos in the core class of 3.2's design, use 94uL of the core pre-working stock), diluted to a total of 200uL of solution (each individual oligo will be at 250nM)

Brainstorming and future projects

Thrombin-aptamer experiments
