  1. Pull aliquots of some high read count and low read count samples. (Pending new low read samples).

  2. Quantify all samples not including blanks or mock community.

  3. For previously low yielding samples, repeat at typical template amount, and at 2x, and 4x volume added to the reaction (in column 2,3,4, and 6, 7, 8). 6x8 samples in low yield, 8 in high yield, 8 of mock community, 8 of blank (ISD only). 72 reactions with different templates. See template below for clarification.

  4. Template layout is replicated/duplicated, with different barcodes for duplicates.

  5. 1 set of 36 products will not be adjusted for pooling.

  6. 1 set of 36 will be adjusted for pooling per qPCR results.

Red samples (bottom half) will either just be pooled per qPCR numbers or concentrated via SpeedVac, reconstituted to a higher concentration, and pooled by qPCR results. (Pending method instructions).

“ul for pooling” was calculated by multiplying the lowest molarity (3.15) times the maximum V available (35 ul) to get ~110. This result was then divided by each sample’s molarity to obtain the ul needed for equimolar pooling rounded to one decimal place.

iSeq Run

Dilute to 1 nM based off qPCR results. qPCR results are in pM, but 1:1000 dilution used. The results are effectively in nM for pool.

...

  • 1000/Results = ul of Pool to Add

1000/____= ____ 53.7 = 18.6 uL of Pool to Add

  • 1000- ul of Pool to Add = ul of “10 mM Tris 8.5” to Add

1000- ____ = ____ 18.6 = 981.4 uL of 10mM Tris 8.5

Red Pool

  • 1000/Results = ul of Pool to Add

1000/___ = ___ 35.3 = 28.3 uL of Pool to Add

  • 1000- ul of Pool to Add = ul of “10 mM Tris 8.5” to Add

1000- ___= ___ 28.3= 971.7 uL of 10mM Tris 8.5

Combine Blue and Red pools in equal parts once pools are at 1nM
