PreAMP cDNA Synthesis Primer Mix - Rat Cytokines & Chemokines

Catalog Number Product Description Price
PBR-150Z For 12 samples
Description
The RT² PreAMP cDNA Synthesis Primer Mixes are used for pre-amplification of cDNA from nanogram amounts of RNA (1-100ng) for multi-gene expression analysis with RT² Profiler PCR Arrays. The RT² PreAMP Rat Cytokines & Chemokines Primer Mix, together with the RT² PreAMP cDNA Synthesis Kit, utilizes multiplex PCR-based pre-amplification to provide amplification of 89 gene-specific cDNA target templates with minimal bias for analysis with the RT² Profiler Rat Cytokines & Chemokines PCR Arrays.

See the Gene List for the RT² Profiler Rat Cytokines & Chemokines PCR Array.

Brief Protocol
Read carefully the User Manual of the RT² PreAMP cDNA Synthesis Kit prior to first-time use. Refer to the instructions in the User Manual every time you use the RT² PreAMP cDNA Synthesis Kit (catalog #330451).
  1. Ensure that you do not contaminate the RT² PreAMP cDNA Synthesis Primer Mix by using a fresh pipette tip every time you draw an aliquot from the tube.

  2. Perform first strand synthesis using the RT² PreAMP cDNA Synthesis Kit as follows:

    A. Add 2 Ál of GE to 8 Ál of RNA (1-100ng). Incubate at 42░C for 5 min and immediately chill on ice.
    B. Mix a master mix for the RT reaction as below:
    For 1 reaction
    BC3 4 µl
    RE 1 µl
    RI 1 µl
    P2 1 µl
    RNase/DNase free H23 µl
    Total10 µl

    C. Add 10 µl of the RT master mix to 10 µl GE-treated RNA.
    D. Incubate at 42ºC for 30 min and heat at 95ºC for 5 min. Chill on ice or store at -20ºC until proceeding to the next step.

  3. For the normal standard reaction, mix the following components in a PCR tube:
     12.5   µl  2X RT² PreAMP PCR Master Mix
     7.5   µl   RT² PreAMP cDNA Primer Mix specific for the RT² Profiler™ PCR Array of your choice
     5.0  µl  Template undiluted cDNA from the 20-µl first strand synthesis reaction (step 2D)
      25.0  µl  final volume

  4. Perform 12 cycles of PCR in a thermal cycler:
    NOTE: The 10 min step at 95ºC is required to activate the HotStart Taq DNA polymerase.
    95ºC, 10 min; 12 cycles of (95ºC, 15 sec; and 60ºC, 2 min); 4ºC forever
  5. Add 2 µl of the Side Reaction Reducer to each pre-amplified reaction, and incubate at 37ºC for 15 min followed by heat inactivation at 95ºC for 5 min.
  6. Dilute the 27-µl pre-amplified templates to 111 µl by adding 84 µl of dd H2O. For immediate use, keep on ice prior to loading onto the RT² Profiler™ PCR Array, or store at -20ºC until ready.
  7. For use in the RT² Profiler™ PCR Array, prepare the Experimental Cocktail with the following components in 15-mL conical tube:
     1275 µl 2X SABiosciences RT² qPCR SYBR Green Master Mix (Note: Use the appropriate master mix specific for your real-time PCR instrument)
     102 µl  diluted PreAMP PCR reaction
    1173 µl ddH2O
      2550 µl  final volume
  8. Add 25 µl of the above Experimental Cocktail to each well of the PCR Array, preferably from a reservoir with an eight-channel pipettor (or a twelve-channel pipettor but only using eight tips).
  9. Run the following real-time thermal cycler program:
    NOTE: The 10 min step at 95ºC is required to activate the HotStart Taq DNA polymerase.
    95ºC, 10 min; 40 cycles of (95ºC, 15 sec; and 60ºC, 60 sec)
  10. Program the real-time thermal cycler to detect and record the SYBR« Green I signal from every reaction during the annealing step of each cycle.
