  • Optimized probe design for aCGH application

    • Compatible with current Agilent microarray platform

      How is different from G4410A ?

    • Add ~2500 biological probes (New genes from Build 35 and additional gap fillers)

    • Retain all biological probes from G4410A with exception of 27 probes

    • Implement CGH eQC grid

Part number: G4410B

Probe Design Methodology

Goal: Provide a utility tool for high throughput, high resolution genome-wide survey and molecular profiling of genomic aberrations.

To construct an array with good coverage of the whole human genome with representation of all known genes emphasizing cancer-related genes and expressed sequences with optimal probe performance.


Slide5 l.jpg

Probe Design Methodology

  • Tiled candidate probes across non-repeat masked regions across the genome in 30 bp steps between cut sites for restriction enzymes (RsaI and AluI)

  • Performed homology search and retained highly specific probes

  • Learned rules for probe performance dependencies on in silico parameters (thermodynamics, complexity, etc.) using chrX probes and M/F cell-line samples

  • Filtered homology-searched probe set on in silico parameters

  • Performed empirical validation on 120,000 semifinal probes using normal M/F cell-line samples and outliers were eliminated

  • Selected the best set of probes biasing toward genes & exons

  • Final probe set within a narrow Tm range


Human genome cgh microarray kit 44b designed for cgh validated with samples of known aberrations6 l.jpg
Human Genome CGH Microarray Kit 44BDesigned for CGH, Validated with samples of known aberrations

  • Consisting of ~43,000 60-mer oligonucleotide probes on 1”x3” slide

  • Genome-wide coverage with average resolution ~35kb*

  • Content source: UCSC Genome Browser hg17 (NCBI Build 35)

  • Probe selection biased toward genes

    1 probe per well known gene

    2 or more probes for each of ~1100 cancer genes

    Intragenic probes (84%); intergenic probes (16%)

    • Optimized probe design for CGH application

    • Ability to detect single copy and homozygous deletions as well as low and high level amplifications

    • Compatible with current Agilent microarray platform

* Calculated by using the total size of the non-repeated genome divided by the total # of features

Genomic Coverage and Probe Distribution

  • NEW CONTENT FROM PREVIOUS G4410A

  • 1. Add ~2500 biologicial probes

    • increase coverage within genomic gaps

    • cover some missing genes base on Build 35

  • 2. Remove 26 probes from 44A

  • 3. Implement a new eQC grid
