In contrast, purification by PEI-beads was fast, facile, and, barring high-ionic strength media, flexible with conditions for probe removal.
The filters were then hybridized using Cy3-labeled probes under appropriate hybridization condition for each probe and washed using appropriate washing buffers.
The capturing condition for each probe set is indicated in brackets after the probe name, where C, G, A, B, L, R, stand for cement surface, grass surface, shoe type A, shoe type B, left view, and right view, respectively.
Temperature and salt concentration are very helpful experimental conditions for a probe to hybridize uniquely to its intended target.
To this end, "difference maps" were computed which plot the difference in response rate between the 2 attentional conditions for each probe position.
Slides were coverslipped, sealed by immersion in mineral oil, and incubated overnight at between 63-67°C 63-67°Cting the optimal in situ conditions foreflectingbe.
In reality, finding unique probes for every target is a difficult task because of the strong similarity of closely related targets, for example, virus subtypes, though temperature and salt concentration are helpful experimental conditions for a probe to uniquely hybridize to its intended target.
Nine filtering conditions were used for probe sets based on their annotations, estimated gene expression levels, splicing index (SI), detection above back ground (DABG) values, and predictions of alternative splicing.
The following PCR conditions were used for probe preparation: 1× PCR buffer (Invitrogen), 1.5 mmol MgCl2/L (Invitrogen), 0.2 mmol/L each of the four dNTPs (Invitrogen), 15 pmol each forward and reverse primers, 1.2 U Taq polymerase.
For each treatment condition, for all 14555 probe sets, the calculated signal log ratios (in base 2) were converted into fold change of mRNA level relative to untreated or control cultures, to make interpretation more intuitive.
