qPCR – Jake’s O.lurida ctenidia 1hr post-mechanical stress DNased RNA

Ran qPCR on DNased RNA from earlier today to assess whether there was any residual gDNA after the DNase treatment with Oly_Actin_F/R primers (SR IDs: 1505, 1504).

Used 1μL from all templates.

All samples were run in duplicate.

Positive control was HL1 O.lurida DNA isolated by Jake on 20150323.

Cycling params:

  • 95C – 2.5mins
  • 40 cycles of:
    • 95C – 10s
    • 60C – 20s
  • Melt curve

Positive control comes up around cycle ~21.

No amplification in the no template controls.

Two wells of the DNased RNA samples exhibit amplification (E3, F6), however the corresponding respective replicate does not. Will proceed with reverse transcription.

qPCR – Re-run Jake’s O.lurida DNased RNA Samples NC1, SC1, SC2, SC4 from 20150514

The following DNased RNA samples showed inconsistencies between qPCR reps (one rep showed amplification, the other rep did not) on 20150514:

  • NC1
  • SC1
  • SC2
  • SC4

Reran these four samples to obtain a definitive answer as to whether or not they have residual gDNA in them prior to using them to make cDNA.

Used Oly_Actin primers (SR IDs: 1504, 1505)

Used 1μL from all templates.

All samples were run in duplicate.

Positive control was HL1 O.lurida DNA isolated by Jake on 20150323.

Cycling params:

  • 95C – 2.5mins
  • 40 cycles of:
    • 95C – 10s

Excluding the no template controls (NTC), all samples produced amplification. Will require DNasing before making cDNA.

Related to the qPCR I ran earlier today with these same primers, the efficiencies of the reactions on this plate are significantly better (i.e. normal; >80% efficiencies) than the earlier qPCR. The improved efficiency would also explain why the positive control comes up two cycles earlier on this run.

In the amplification plots below, the positive control reps are the two lines coming up at cycle ~20.

Excluding the no template controls (NTC), all samples produced amplification. Will require DNasing before making cDNA.

On a side note, it should be noted that the efficiencies for all of the reactions were pretty bad; probably averaging 50%. Not entirely sure why or what that indicates.

In the amplification plots below, the positive control reps are the two red lines coming up at cycle ~22.
