PyroMark Q24 MDx User Manual 01/2016

Comments and suggestions

m) Unusually high

consumption of
substrate (noted as

a high
presequencing
signal)

Prepare samples according to the instructions in

Section 5.3.
Change buffers and do not use any other buffers
than those supplied by QIAGEN.
Check if any peaks have been generated using
the zoom in function (select a stretch of Pyrogram

with the left mouse button).

n) Crosstalk (light from

one well appears in

the neighboring
well)

Avoid placing assays with high signals close to
assays with low signals.

o) Dispensation error Replace the reagent cartridge. If the problem

remains, contact QIAGEN Technical Services.

p) Unknown SNP in

sample

Insert the SNP in the sequence to analyze and

regenerate the dispensation order. Rerun the
sample with the new dispensation order.

q) dUTP used in the

PCR reaction

Replace dUTP with dTTP since the A nucleotide

used in Pyrosequencing reactions binds less
stringently to dUTP.

r) Plus shift

Change the dispensation order.

s) Minus shift

Ensure that homopolymers are followed by an

extra dispensation.
