DNA Microarray Facility Back

( Prithviraj Chavan, Ch. Mohan Rao & M. B. Madhavi)

Microarray is a high-throughput technique for analyzing expression levels of thousands of genes or genotyping large numbers of SNPs in a single experiment.

Facility is equipped to do genome wide analysis with applications in basic research as well as in biomedicine and agro-biotechnology. Microarrays (also known as DNA/Gene chips) are generated by a technology that integrates molecular biology and information technology.  

We have both major array platforms:

  • Spotted Array
  • Affymetrix

Spotted Array System:

  • Generation III Array Spotter (can spot 9,216 features on 36 slides)
  • Axon Gene Pix 4000B Scanner
  • Instrument Control DELL Optiplex 755 (Pentium 1.8GHz, 2GB RAM, XP Prof. 2002-OS)
  • GenepixPro 7.0 (Image Analysis s/w)
  • Analysis HP xw8600 Wks (Xeon 2.0GHz, 8GB RAM, XP Prof. x64 2003-OS)
  • Acuity 4.0 (Data Analysis s/w)

Affymetrix System:

It is being extensively used for genotyping applications and gene expression studies.

  • Hybridization Oven 640
  • Fluidics Station 450
  • Scanner 450
  • Instrument Control DELL Workstation (Xeon 3GHz, 2GB RAM, XP Prof. 2002-OS).
  • Affymetrix Genechip Command Console (Image/Data Analysis s/w)
  • Genespring 11.5 (Data Analysis s/w)
  • Analysis HP z600 Wks (Xeon 2.67GHz, 16GB RAM, x64 Win.Prof.7-OS).
