  • Instructions for Submitting RNA Samples For MicroArray

    Submit cellular total RNA extracts (100ng in 5-10 ul RNase-free H2O or buffer) in sterile, Rnase-free microfuge tubes.

    1. In general, 50-100ng high quality cellular RNA is needed to obtain sufficient quantity of labeled-cRNA using WT-protocol, for hybridization to GeneChip arrays. 
    2. Cellular RNA less than 5ng will be labeled using WT-pico protocol.
    3. For miRNA arrays, submit 0.5-1.0ug cellular RNA in 10ul RNase-free H2O. 

    The core facility staff does not extract and prepare RNA from cells or tissues.

    Note:  The quality of the RNA is essential to the overall success of the GeneChip analysis. Since the most appropriate protocol for the isolation of RNA can be source material-dependent, we recommend using a protocol that has been established for the tissues and cells being used.  Or if you do not have an established protocol, we suggest using one of the commercially available kits designed for RNA isolation, following the manufacturer's instructions.

    Good quality RNA has been obtained using the kits listed below:

    • Total RNA preparation from cells:  QIAGEN's RNeasy Total RNA Isolation kit.
    • Total RNA preparation from tissues:  Invitrogen Life Technologies' TRIzol reagent.
  • What Is MicroArray Analysis?

    Chromosomal microarray analysis (CMA). CMA is a new laboratory test used to detect chromosomal imbalance at a higher resolution than current standard chromosome or FISH techniques.

    A sample of DNA from the individual to be tested and a control DNA sample are arranged in a particular order (array) on a glass slide. Fluorescent dyes are attached to the DNA samples. These slides are then placed in a special scanner that measures the brightness of each fluorescent area.

    This process looks for identification of a change in DNA copy number. These changes in DNA copy number may represent changes seen in the general population that do not cause genetic diseases. However, some changes in copy number may indicate a chromosomal abnormality, such as a chromosomal imbalance, loss, or gain. Types of chromosomal abnormalities may include small chromosomal rearrangements, small duplications of chromosomal material (trisomy), or small deletion of chromosomal material (monosomy).
