Agilent genomic dna uls labeling kit

Manufactured by Agilent Technologies
Sourced in Netherlands

The Agilent Genomic DNA ULS Labeling Kit is a product designed for the labeling of genomic DNA samples. The kit utilizes the Universal Linkage System (ULS) technology to facilitate the efficient incorporation of labels into DNA fragments, enabling their subsequent detection and analysis.

Genome-wide DNA Copy Number Array for ERG Deletions

Check if the same lab product or an alternative is used in the 5 most similar protocols
To identify ERG deletions, genome-wide DNA copy number arrays were performed as described previously4 (link). Briefly, Agilent SurePrint G3 Hmn 4 × 180 K arrays (Agilent Technologies, Amstelveen, the Netherlands) were co-hybridized with 1 μg patient DNA labeled with ULS-Cy5 and 1 μg reference genomic DNA male pool (G147A, Promega, Leiden, the Netherlands) labeled with ULS-Cy3 (Agilent Genomic DNA ULS Labeling Kit). Using median log ratios, data were normalized using the CGHcall47 (link) version 2.14.0, centralized using CGHnormaliter48 (link) version 1.8.0, and segmented and called using CGHcall default settings (−1 for loss, 0 for diploid, 1 for gain and 2 for amplification) in R version 2.14.1.

Copy number analysis was performed using Agilent SurePrint G3 Hmn 4×180K arrays (Agilent Technologies, Amstelveen, the Netherlands) co-hybridized with 1 μg patient DNA labeled with ULS-Cy5 and 1 μg reference genomic DNA male pool (G147A, Promega, Leiden, the Netherlands) labeled with ULS-Cy3 (Agilent Genomic DNA ULS Labeling Kit). Copy number microarray data were normalized using median log ratio in the CGHcall [27 (link)] version 2.14.0, centralized using CGHnormaliter [28 (link)] version 1.8.0, and segmented and called using CGHcall default settings (−1 for loss, 0 for diploid, 1 for gain and 2 for amplification) in R version 2.14.1.

Oligo Array CGH Analysis of Dedifferentiated Tumors

Check if the same lab product or an alternative is used in the 5 most similar protocols
High-resolution oligo array comparative genomic hybridization analysis was used for a subset of samples of 12 tumors from 9 patients, including three usual (nos. 1, 2, and 6), five malignant (nos. 8, 9, 10, 22a, and 23a), and four dedifferentiated tumors (nos. 22b, 23b, 24a, and 24b). The samples taken from three patients (nos. 22, 23, and 24) were from the primary (no. 22a) or the earliest available lesion (Nos. 23a and 24a) and the subsequent dedifferentiated recurrence (nos. 22b, 23b, and 24b). Genomic DNA was extracted from the frozen samples by using a DNeasy Tissue Kit (Qiagen, Valencia, CA, USA) including RNase treatment, and its quality was assessed by using NanoVue (VWR) and agarose gel electrophoresis. The molecular karyotype of the samples was assessed by using an Agilent 144K array and an Agilent Genomic DNA ULS labeling kit in accordance with the manufacturer's protocol, and the raw data were processed using 'Feature extraction' software (Agilent Technologies, Santa Clara, CA, USA).
The data were analyzed using Agilent's Genomic Workbench Standard Edition 6.5.0.58. Copy-number variations, low-level copy-number abnormalities (0.3 olog2 ratio4 -0.3), and copy-number abnormalities involving chromosomes X and Y were not considered.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
